After 1 second the meter activates the automatic buffer recog-nition feature. If a valid buffer is detected, then its value is shown on the primary display, and REC appears on the secondary LCD. If no valid buffer is detected, the meter keeps the USE indication active for 12 seconds, and then re-places it with WRNG , indicating that the sample being measured is not a valid buffer.•For a single-point calibration with buffers pH 4.01, 9.18 or 10.01, the meter automatically accepts the calibration when the reading is stable; the meter will show on the primary dis-play the accepted buffer, with the message “OK 1” on the secondary display, and an audible signal is produced. After 1 second the meter automatically returns to the normal measur-ing mode.If a single-point calibration with buffers pH 7.01or 6.86 is desired, then after the calibration point has been accepted the ON/OFF/MODE button must be pressed in order to return to the nor-mal measuring mode. After the button is pressed, the meter shows "7.01" (or "6.86") -"OK 1", and an audible signal is produced. Af-ter 1 second, the meter automatically returns to the normal measuring mode.Note : It is always recommended to carry out a two-point calibration for better accuracy.•For a two-point calibration , place the probe in pH 7.01 (or pH 6.86) buffer. After the calibration point has been accepted, the “pH 4.01 USE”message appears. The message is held for 12 seconds, unless a valid buffer is recog-nized. If no valid buffer is recognized, then the WRNG message is shown. If a valid buffer (pH 4.01, pH 10.01 or pH 9.18) is detected, then the meter completes the calibration procedure.When the buffer is accepted, the LCD shows the accepted value with the “OK 2” message on the secondary display. The meter then re-turns to the normal measuring mode.Note : When the calibration procedure is com-pleted, the CAL tag is turned on.To quit calibration and to reset to the de-fault values•After entering the calibration mode and before the first point is accepted, it is possible to quit the procedure and return to the last calibration data by pressing the ON/OFF/MODE button.The secondary LCD displays ESC for 1 sec-ond and the meter returns to normal mode.•T o reset to the default values and clear a previ-ous calibration, press the SET/HOLD button after entering the calibration mode and before the first point is accepted.The meter displays the remaining battery per-centage when turned on. When the level is below 5%, the symbol on the bottom left of the LCD blinks to indicate a low battery condition. If the battery level is low enough to cause erroneous readings, the Battery Error Prevention System (BEPS) turns the meter off.Unscrew the 4 screws located on the back of the meter and carefully replace the 3 AA batteries lo-cated in the battery compartment, while paying attention to their polarity . Reattach the back mak-ing sure that the gasket is in place and tighten the 4 screws to ensure a watertight seal.The secondary LCD displays CLR for 1 sec-ond, the meter resets to the default calibration and the “CAL” tag on the LCD disappears.。

The temperature probe can be used independently to take temperature measurements, or it can be used in conjunction with the pH electrode to utilize the meter's ATC capability. If the probe is disconnected, temperature can also be set manually with the UP and DOWN keys. Toswitch the instrument on, press and hold theON/OFF key for a fraction of a second. The meter has a built-in protection against electro-magnetic interference and the delayed response of the keys assures that the commands are not mistaken for stray signals.HI 9110 and HI 9210:Connect the pH electrode to the BNC connector on the top of the instrument and press the ON/OFF key.HI 9210N and HI 9023CN:Connect the pH/ C electrode to the DIN connector on the top of the instrument and press the ON/OFF key.13pH MEASUREMENTSTo take a pH measurement remove the elec-trode protective cap and simply submerge the tip (4cm/1½") of the electrode and the tem-perature probe (wherever applicable) into the sample to be tested.Turn the instrument ON and if necessary, press RANGE until the display changes to the pH mode.Allow for the electrode to adjust to the solution and stabilize.In order to take more accurate pH measurements, make sure that the instrument is calibrated (see page 16).It is recommended that the electrode is always kept wet and rinsed thoroughly with the sample to be measured before use.The pH reading is directly affected by temperature. In order for the meter to measure the pH accurately, temperature must be taken in consideration. If the sample temperature is quite different from the temperature at which the pH electrode was kept, allow a few minutes for a perfect thermal equilibrium between them.HI 9023C, HI 9024C and HI 9025C:To use the meter's Automatic Temperature Compensation feature,submerge the temperature probe into the sample as close to the electrode as possible and wait for a couple of minutes. If you know the temperature of the sample to be tested you can manually compensate for it.If manual temperature compensation is desired the temperature probe must be disconnected from the instrument .The display will show the default temperature of 25 C or the last recorded temperature read-ing with the "C" indicator blinking.The temperature can now be adjusted with theUP and DOWN keys.14HI 9023C, HI 9023CN and HI 9210NTo use the meter's Automatic Temperature Compensation feature,simply submerge the pH/ C electrode into the sample and wait for a couple of minutes. The pH electrode also houses the temperature sensor which will measure and adjust for the temperature effect automatically.HI 9110, HI 9210:To use the meter’s Manual Temperature Compensation feature:Press the pH/ C key of HI 9110 or the RANGE key of HI 9210 to select the manual temperature mode.Remove the protective cap on top of the meter to access the trimmers. Measure the temperature of the buffer with a Checktemp or an accurate thermometer.Using the calibration screwdriver, turn the temperature trimmer (#5 pages 9-10) to display the measured temperature value.Press the pH/ C key of HI 9110 or the RANGE key of HI 9210 to return to the pH measurement mode.When finished, switch the instrument off and rinse the electrode with clean water. Pour a few drops of HI 70300 storage solution,or in its absence, pH 7 or pH 4 buffers in the protective cap andreplace it before storing away the electrode.15ORP MEASUREMENTS (HI 9023C AND HI 9025C)To enter the "mV" mode (ORP or ISE), turn the instrument ON and press the RANGE key until the display changes to mV.To measure the mV of a solution simply submerge the ORP or ISE electrode tip (4cm/1½") into the sample to be tested. Allow a few minutes for the readings to stabilize. See also "Taking REDOX Measurements" section at page 29.TEMPERATURE MEASUREMENTS (HI 9023C,HI 9023CN, HI 9024C, HI 9025C AND HI 9210N):Taking a temperature measurement is very easy. Turn the instrument ON and press the RANGE key to enter temperature mode.For HI 9023C , HI 9024C and HI 9025C , dip the liquid/general purpose temperature probe HI 7669/2W into the sample. For HI 9023CN and HI 9210N , simply dip the pH/ C electrode which contains the temperature sensor. Then allow a couple of minutes for the reading to stabilize.Note:You can also calibrate the offset point of the HI 9210N tem-perature sensor, if needed. For this purpose, immerse the pH/C electrode in a solution at a known temperature. Then turn the #5 trimmer (see page 10) until the temperature dis-played on the LCD is that of the solution.16It is recommended to calibrate the instrument frequently, especially if high accuracy is required.The instrument should be recalibrated for pH:a)Whenever the pH electrode or temperature probe is replaced.b)At least once a month.c)After testing aggressive chemicals.d)Whenever the batteries have been replaced.e)If greater accuracy is required.PREPARATIONPour small quantities of pH 7.01 and pH 4.01 solution into two clean beakers.For accurate calibration use two beakers for each buffer solution, the first one for rinsing the electrode and the second one for calibration.This way contamination of buffer is minimized.To obtain accurate readings, use pH 7.01 and pH 4.01 buffers if you are going to measure acidic samples, or pH 7.01 and pH 10.01 for alkaline measurements.PROCEDURE FOR HI 9023C AND HI 9023CN:•Make sure that the meter is in the pH mode.•Remove the protective cap from the elec-trode, rinse it with some pH 7.01 solution,then immerse the pH electrode and tem-perature probe (HI 9023C HI 9023C HI 9023C) or the pH/C electrode (HI 9023CN HI 9023CN HI 9023CN) into pH 7.01 buffer solution and stir gently and wait for the reading to stabilize.17Note:The electrode should be submergedapproximately 4 cm (1½") into the solution. With the temperature probelocated as close to it as possible (HIHI 9023C 9023C).•Press the CAL key. The temperature compensated pH value will blink on the display. For example, if the temperature is 25 C the reading will be pH 7.01. If the temperature is 20 C the readingwill be 7.03. The pH/temperature con-version chart is on page 24.Note:If "E4" flashes, the buffer solution iswrong or the probe is defective (see page 25 for trouble-shooting).•Wait for the "pH" symbol to stop flashing and press the CFMkey. The symbol "E5" will flash to indicate that the electrode is still in the pH 7.01 buffer.•Rinse the pH electrode (and the tem-perature probe) with distilled water first and with the pH 4.01 (or 10.01) buffer after.•Dip the electrode (and the temperatureprobe) into the pH 4.01 (or 10.01) buffer solution. Stir gently and wait for the reading to stabilize.•The "E5" symbol should disappear and the temperature com-pensated value will blink on the display.For example, if you are using pH 4.01 as the buffer, the reading will be 4.01 at 25 C.•When the "pH" symbol stops flashing,press CFM to confirm the calibration.The instrument is now calibrated and will remain calibrated even18when it is turned off.Note: The meter will lose the calibration ifthe batteries are removed.HI 9023C only:To calibrate with manual temperature com-pensation , follow this procedure:•Disconnect the temperature probe and switch the instrument ON.•Press RANGE to select the temperature mode.•Place the pH electrode into the 7.01 buffer stir gently and wait for the LCD to stabilize.•Record the buffer temperature by using a Checktemp C or anC).•Press the UP and DOWN to adjust the temperature accordingly.•Press RANGE to display pH and then press the CAL key. The•Wait for the "pH" symbol to stop flash-ing.•Press CFM. The "E5" symbol will flash to indicate that the electrode is still in the 7.01 solution.19•Rinse the electrode with clean or distilled water first and then with pH 4.01 (or 10.01) buffer. Dip the electrode into the pH4.01 (or 10.01) solution and stir gently.•Wait for the "pH" symbol to stop flashing. Press CFM to confirm the calibration.PROCEDURE FOR HI 9024C AND HI 9025C:In order to calibrate HI 9024C and HI 9025C , there is a choice of 5 memorized buffers: 4.01, 6.86, 7.01, 9.18 and 10.01 pH.•Make sure that the meter is in the pH mode.•Remove the protective cap and rinse the electrode with some of the buffer calibration solution that you are going to use first.ONE-POINT CALIBRATION:It is always recommended to perform a two-point calibration for optimum accuracy. In case of necessity, it is possible to carry out only a one-point calibration with the instruments. The offset buffers, that is the Standard 7.01 or the NIST 6.86 are the most appropriate for this purpose even though both meters can be calibrated with any of the 5 memorized calibration solutions.•Immerse the pH electrode into a pHbuffer solution (e.g. pH 6.86) and stir gently.Note: The electrode should be submerged approximately 4 cmas close to it as possible.20•Once the electrode is submerged in the buffer solution, the LCD will notify the user if the reading is not stable by an intermittent "NOT READY". Only when the reading is stable, will it change to a blinking "READY" and "CON".•Press the CFM key to confirm the calibra-tion. If the reading is not close to theselected buffer, "WRONG 1" and "WRONGclose to the selected buffer, the meter stores the reading (and adjusts the offset point). The buffer value is then displayed on the primary LCD and the secondaryLCD will display another buffer value (e.g."4.01").•Press the CAL key and the calibration pro-cess is ended with only the offset of the meter calibrated. For best accuracy how-ever, do not press CAL and proceed with a two-point calibration.TWO-POINT CALIBRATIONAfter calibrating at 6.86 or 7.01 pH (see above), for the second buffer use pH 4.01 if you are going to measure acidic samples,and pH 9.18 or pH 10.01 if you are measuring alkaline solutions.•Proceed as described in “One-point cali-bration above but do not end the calibration by pressing CAL.•After the first calibration point is con-firmed, immerse the pH electrode into the second buffer solution (pH 4.01,9.18 or 10.01) and stir gently.Note: The electrode should be submergedapproximately 4 cm (1½") into the solution with the temperature probe located as close to it as possible.•secondary display by pressing the Ïor Ð C C key.21Note: The electrode should be submergedapproximately 4 cm (1½") into the solution with the temperature probe located as close to it as possible.•Select the second buffer value on the secondary display bypressing the Ï°C or ÐC key.•When the “READY” and “CON” symbols blink on the display,the reading is stable and the calibration can be confirmed.•Press the CFM key. If the reading is not close to the selected buffer solution, “WRONG 2” and “WRONG ” will blink alternatively. If the reading is close to the selected buffer, the slope and the offset are calibrated. The values will be stored in memory and the meter will return to the operating mode.Note:The meter will automatically skip the buffer that was usedfor the first calibration to avoid erroneous calibration. At least 1 full pH unit is required between the two buffers used for the offset and slope calibration. As a result, once calibrated at either pH 6.86 or 7.01, the microprocessor will automatically ignore the other one for the second point calibration. It will do likewise for pH 9.18 and 10.01Note:During calibration, the secondary LCD displays the selectedbuffer value. With HI 9025C, press the RANGE key to display the buffer temperature during calibration.PROCEDURE FOR HI 9110, HI 9210 & HI 9210N:Manual Temperature CompensationNote:The pH/ C electrode of HI 9210N incorporates a tempera-compensation. Consequently, the following 5 paragraphs are irrelevant to HI 9210N and you can just proceed withpH calibration below.22•Press pH/ C SET key for HI 9110 or the RANGE key for HI 9210 to select the manual temperature setting. The "C"symbol will be displayed to indicate the temperature setting mode.•Remove the protective cap on the top of the meter to have access to the calibration trimmers.•an accurate thermometer (e.g.20C).•Using the screwdriver, turn the temperature trimmer (# 5pages 9-10) to display the recorded temperature value.•Press the pH/ C SET key for HI 9110or the RANGE key for HI 9210 to read pH.pH CalibrationAll three meters provide for manual pH cali-bration. As a result, you can perform one or two point calibration at a buffer of your choice. The instructions below explain a typical calibration procedure at pH 7 and then 4 or 10.•Remove the protective cap from the elec-trode, rinse it with some pH 7.01 solution, then dip in pH 7.01 buffer. Stir briefly and wait for one minute for the reading to stabilize.Note:23(1½") into the solution. For HI 9110 andHI 9210, place the thermometer close to the pH electrode.•Adjust the OFFSET trimmer (#3 pages 9-10) until the LCD shows the pH value atthe buffer temperature (see page 24 for pH values at various temperatures). With HI 9210N , press RANGE to read the buffer temperature.•Rinse first with clean or distilled water and then with a small amount of the next buffer (2nd calibration point). Dip the electrode into pH 4.01 (or 10.01) buffer, stir gently and wait until the display has stabilized.•Adjust the SLOPE trimmer (#4 pages 9-10) until the LCD displays the pH value at the second buffer temperature (see page 24).•pH calibration is now complete. Once the calibration process is complete, replace the trimmer cover and tighten it to ensure a proper seal against water and humidity ingress.24Temperature has an effect on pH. The calibration buffer solutions are affected by temperature changes to a lesser degree than normal solutions.For manual temperature calibration (standard with HI 9110 and HI 9210 or optional with HI 9023C , HI 9024C and HI 9025C )please refer to the following chart.For instance, if the buffer temperature is 25 C, the display should show pH 4.01, 7.01 or 10.01 at pH 4, 7 or 10 buffers, respectively.At 20 C, the display should show pH 4.00, 7.03 or 10.06. The meter reading at 50 C will then be 4.06, 6.98 or 9.82.p TEMP pH VALUES °C °F4.01 6.867.019.1810.0151015202530354045505560657032415059687786951041131221311401491584.014.004.004.004.004.014.024.034.044.054.064.074.094.114.126.986.956.926.906.886.866.856.846.846.836.836.846.846.856.857.137.107.077.047.037.017.006.996.986.986.986.986.986.996.999.469.399.339.279.229.189.149.109.079.049.018.998.978.958.9310.3210.2410.1810.1210.0610.019.969.929.889.859.829.799.779.769.752526ELECTRODE CONDITIONING& MAINTENANCEPREPARATIONRemove the protective cap.DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is normal with electrodes and they will disappear when rinsed with water.During transport tiny bubbles of air may form inside the glass bulb affecting proper functioning of the electrode. These bubbles can be removed by "shaking down" the electrode as you would do with a glass thermometer.If the bulb and/or junction is dry, soak the electrode in HI 70300 or HI 80300 Storage Solution for at least one hour.* Not present in gel electrodes.27For refillable electrodes:If the filling solution (electrolyte) is more than 2½ cm (1") below the fill hole, add HI 7082 or HI 8082 3.5M KCl Electrolyte Solution for double junction or HI 7071 or HI 8071 3.5M KCl+AgCl Electrolyte Solution for single junction electrodes.For a faster response, unscrew the fill hole screw during measure-ments.For AmpHel ®electrodes:If the electrode does not respond to pH changes, the battery is run down and the electrode should be replaced.MEASUREMENTRinse the electrode tip with distilled water. Immerse the tip (bottom 4cm /1½") in the sample and stir gently for a few seconds.For a faster response and to avoid cross contamination of the samples,rinse the electrode tip with a few drops of the solution to be tested,before taking measurements.STORAGETo minimize clogging and assure a quick response time, the glass bulb and the junction should be kept moist and not allowed to dry out.Replace the solution in the protective cap with a few drops of HI 70300or HI 80300 Storage Solution or, in its absence, Filling Solution (HI 7071 or HI 8071 for single junction or HI 7082 or HI 8082 for double junction electrodes). Follow the Preparation Procedure above before taking measurements.Note:NEVER STORE THE ELECTRODE IN DISTILLED OR DEIONIZED WA-TER.PERIODIC MAINTENANCEInspect the electrode and the cable. The cable used for connection to the meter must be intact and there must be no points of broken insulation on the cable or cracks on the electrode stem or bulb.Connectors must be perfectly clean and dry. If any scratches or cracks are present, replace the electrode. Rinse off any salt deposits with water.For refillable electrodes:Refill the reference chamber with fresh electrolyte (HI 7071 or HI 8071for single junction or HI 7082 or HI 8082 for double junction elec-trodes). Allow the electrode to stand upright for 1 hour.Follow the Storage Procedure above.AmpHel ® is a registered Trademark of "Hanna Instruments"28CLEANING PROCEDUREGeneralSoak in Hanna HI 7061 or HI 8061 General Clean-ing Solution for approximately ½ hour.Removal of films, dirt or deposits on the membrane/junction:- Protein Soak in Hanna HI 7073 or HI 8073 Protein Clean-ing Solution for 15 minutes.- Inorganic Soak in Hanna HI 7074 or HI 8074 Inorganic Clean-ing Solution for 15 minutes.- Oil/grease Rinse with Hanna HI 7077 or HI 8077 Oil and FatCleaning Solution.IMPORTANT: After performing any of the cleaning procedures rinse the electrode thoroughly with distilled water, refill the refer-ence chamber with fresh electrolyte (not necessary for gel-filled electrodes) and soak the electrode in HI 70300 or HI 80300Storage Solution for at least 1 hour before taking measurements.TROUBLESHOOTINGEvaluate your electrode performance based on the following.•Noise (Readings fluctuate up and down) could be due to:– Clogged/Dirty Junction: Refer to the Cleaning Procedure above.– Loss of shielding due to low electrolyte level (in refillable electrodes only): refill with fresh HI 7071 or HI 8071 for single junction or HI 7082 or HI 8082 for double junction electrodes.•Dry Membrane/Junction: Soak in HI 70300 or HI 80300Storage Solution for at least 1 hour.•Drifting: Soak the electrode tip in warm (approx. 50-60C)Hanna HI 7082 or HI 8082 Solutions for one hour and rinse the tip with distilled water.

to many plants,but some plants may even be affected adversely by concentra-tions lower than 1.0mg/L.The US Department of Agriculture reports the following classifi-cation:ppm of Boron effect on crops <0.5good (except for very sensitivecrops)0.5-2.0some risks (many crops mustbe excluded)>2.0dangerous (may only be usedfor very tolerant crops)Note:mg/L is equivalent to ppm (parts per million).The Hanna Test Kit allows the determination of boron concentration in irrigation waters by direct titration of boric acid.READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT •Calibrate the pH electrode following the instructions in the Checker instrument manual.Range 0to 5mg/L (ppm)as Boron Smallest Increment 0.2ppm Boron Analysis Method Titration Sample Size 50mL Numberof Tests 100Case Dimensions

Checkervessel and measure lower than 7.If pH HI 38074B-0ing after each drop,than 7.•Using one of the Boron Reagent,swirling after each drop.•Keep on adding HI 38074C-0reagent until the pH reaches the 7.8±0.2value.Write down the exact pH value and report it as pH start (e.g.:pH start =7.85).Note 1:If pH stabilizes at a value higher than 8,toomany drops of HI 38074C-0reagent have been added.In this case,add 1drop of HI 38074B-0reagent and swirl,then add again drops of HI 38074C-0to adjust the pH to 7.8±0.2.Note 2:If carbonates are present,the pH readings willshow a drift after each addition.Wait until the pH stabilizes before adding the next drop of HI 38074C-0reagent.•Add 1packet of dissolve.•Measure the pH:-If pH is lower than pH start (e.g.:pH=7.52),use the other plastic pipette to add HI 38074E-0Boron Reagent drop by drop,swirling after each drop,while keeping an accurate count of the number of drops being added to the solution.Keep adding the reagent until pH becomes equal or higher than pH start (7.85).Use the Boron Conversion Table below to convert the number of drops added in mg/L (or ppm)of Boron (e.g.:10drops of HI 38074E-0reagent correspond to 2.0mg/L of Boron).-If pH does not change after addition of the powder packet,boron is absent.As a confirmation,add one drop of HI 38074E-0reagent and pH will immedi-ately increase a lot.x350BORON CONVERSION TABLEnumber mg/L number

in this kit may be hazardous if improperly handled.Read the relevant Health and Safety Data Sheet before performing thistest.P.Sequi,Chimica del suolo ,Patron editore,Ed.1991Interferences•Compounds with buffering capacity (substances that keep the pH of sample at a constant value,e.g.phosphate buffer,ammonia buffer):if after Mannitol reagent has been added pH of sample does not change,verify if pH increases a little (0.05pH units)by adding HI 38074E-0reagent drop by drop.In this case boron may be present,but a buffer interferes with boron determination.It is possible to have only an indication for boron e the Boron Conversion Table below to convert the number of drops added in mg/L (or ppm)of Boron and record the concentration of boron in your sample as lower than the value found (e.g.:2drops correspond to 0.4mg/L of Boron,thus boron concentration in your sample is lower than 0.4mg/L).•Bicarbonates:if hardness of sample is about 150ppm CaCO 3,bicarbonates are present at pH 8.3,and they interfere with boron determination.In this case the sample needs to be pretreated before analysis as de-scribed in the following paragraph.Pretreatment to eliminate carbonate interference •Fill the plastic vessel with 50mL of sample and pour it into the empty bottle.•Add HI 38074B-0reagent until pH is lower than 4.5.Place the cap,but DO NOT SCREW IT.•Heat the sample for about 45seconds in a microwave oven at 500W (do not boil the sample).Swirl several times to eliminate air bubbles and allow the sample to cool down to room temperature.Pour the sample into the plastic vessel and perform the test as described above.。
