溶解氧操作规程

溶解氧操作规程

溶解氧仪操作规程一、原理本方法所采用的探头由一小室构成,室内有两个金属电极并充有电解质,用选择性薄膜将小室封闭住。

实际上水和可溶解物质离子不能透过这层膜,但氧和一定数量的其他气体及亲水性物质可透过这层薄膜。

将这种探头浸入水中进行溶解氧测定。

二、操作步骤1、将DO探头的缆线连接头插入仪器顶部的输入端口。

2、将电源插头一端插入仪器顶部端口,一端插入230V,50/60HZ的电源插座。

3、校准100%:打开源,使仪器处于测定状态,这时电极应套在护罩内进行校准,按cal键,连续按enter键四下,这时仪表会显示stabilizing并闪烁,当听到仪器“叮”的提示音后,仪器自动校准完毕。

4、将探头插入样品中至所需深度,探头必须插得足够深,使探头侧面的热敏电阻(金属钮扣状物)被淹没。

5、在样品中搅动探头驱赶探头顶端敏感区存在的气泡。

6、用探头剧烈搅动样品,当测量水体的深处时,扯动缆线让探头上下移动使探头顶端有足够的流体流过。

7、仪器上读数稳定后,记录该数据。

8、关闭电源,取下探头,用纯水冲洗干净,插入带有水或湿海绵的保存池内。

二、维护和保养1、该仪器设计成免维护的形式。

如果仪器弄脏了,请用一块湿布擦拭表面。

如果连接头弄湿了,请用棉签将其清洁并干燥。

2、DO探头维护:每隔一定时间或当膜被破坏、被污染时需要更换膜盖并补充新的填充电解液(放在冰箱内保存)。

如果膜未被损坏污染,建议更换电解质填充液的时间间隔为1—2个月。

3、在更换膜盖之前,用随电极附带的抹布擦拭阳极(探头的外侧金属杆,除去膜盖时可看到)。

抹布可除去会降低探头操作性能的沉积物。

如果经过一段时间后探头性能减退,则无论时更换膜盖时还是更换膜盖的间隙间均要擦拭阳极。

四、注意事项1、DO电极仅用于液体。

2、在拿和存放氧气膜盖时一定要额外当心。

3、为了得到最佳操作性能,每天使用之前请进行校准,为了得到最大精度,请每隔两小时重新校准DO探头一次。

4、样品必须具有较高流速或被快速搅拌,以获得精确的测量结果。

User's GuideExStik® DO600 Dissolved Oxygen MeterDO600-EU-EN-V7.0- 8/102123456789MembraneViewIntroductionCongratulations on your purchase of the ExStik ®DO600 dissolved oxygen / temperature meter which simultaneously displays dissolved oxygen and temperature. Units of measure are % saturation, mg/l or ppm for dissolved oxygen, and °C or °F for temperature. Advanced features include Data Hold, 25 points memory, auto power off, automatic temperature compensation, salinity and altitude compensation. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.Meter DescriptionFront Panel Description1. Battery compartment cover2. LCD Display3. MODE/HOLD button4. CAL/RECALL button5. ON/OFF button6. Electrode Retaining Collar7. Dissolved Oxygen Sensor8. Bonded Membrane Cap assembly9. Membrane & Cathode(Note: The Electrode storage cap is not shown)LCD Display1. Bar graph display2. Measurement units3. Main display4. Low Battery indicator5. Temperature display6. Reading hold indicatorOperation®Prepare the Electrode1. The electrode is shipped “dry” and requires filling with the supplied electrolyte solutionbefore use. The membrane should be in place and does not need replacement.Follow the procedure at the end of this guide for filling the bonded cap.Powering the ExStik®The ExStik® uses four (4) CR2032 Lithium Ion Batteries. Press the ON/OFF button to turn the meter on or off. If the batteries are weak, the ‘BAT’ indicator appears on the LCD. The auto power off feature shuts the ExStik® off automatically after approximately10 minutes of inactivity. The auto power off feature may be temporarily disabled forconvenience or for extended polarization time.Startup Polarization PeriodWhen the ExStik® is powered up for the first time, the electrode requires polarization. In order for this to occur a three minute (approx.) polarization period must elapse before measurements can be made. A special circuit is included in this meter which, upon turn-on, maintains a very small biasing current to the electrode for a period of seven days. This keeps the electrode polarized and enables the user to make immediate measurements (within a 7 day period) without waiting for the electrode to re-polarize. Each time the ExStik® is turned on, the polarization timer is reset and the 7 day polarization period is initiated. A small asterisk at the bottom right corner of the display is used to indicate that the polarization timer circuit is active. If the ExStik is not used for more than seven day, a 3 minute waiting period is required before a measurement can be made.Turn-On Diagnostics2. When the meter is turned ON the LCD displays “SELF” and “CAL” while the meterruns a diagnostic routine.3. During this time the meter is recalling the User Calibration data, performing selfdiagnostics & initializing the circuitry.4. After this function is complete, the meter proceeds to the normal measurement mode. Measurements1. Cover the electrode with the electrode cap. The sponge contained in the cap shouldbe moistened (not soaked) with DI (distilled water) or clean tap water.ON/OFF button turns the meter ON or OFF. When turned ON, the2. Pressingthemeter’s display switches on and the Self Calibration utility runs (see above). The unit of measure selected when the meter was last turned OFF will remain on the display.3. If this is the first time the meter is powered up, wait approx. 3 minutes for the probe topolarize (please disable auto-power off; Instructions for disabling auto-power off areprovided in a later section). For more details, please read the Startup PolarizationPeriod paragraph earlier in this manual before continuing.4. Select the desired units of measure by pressing and holding the MODE/HOLD buttonuntil the proper units are shown in the display. Remove the electrode cover and place the electrode in the sample to be measured. Stir the electrode in the sample toremove any trapped air bubbles from the membrane surface. Do not submerse theelectrode to the point that the sample liquid reaches the meter’s electrode collar.5. Allow the meter time to settle to the final measurement value.Note: The larger the difference in temperature between the electrode and the solution the longer it will take for the reading to stabilize. Stabilization time can vary from ten(10) seconds to five (5) minutes.DO600-EU-EN-V7.0- 8/103Calibration1. Calibration should be performed on a daily basis.2. Turn the meter ON3. Press and hold the MODE/HOLD button until % is displayed on the LCD.4. If the meter has not been used for seven (7) days or longer, allow the electrode tofully polarize. This may take 2-3 minutes.5. Place the electrode cap onto the electrode. The sponge contained in the cap shouldbe moistened (not soaked) with DI (distilled water) or clean tap water. Be sure that the electrode membrane is clean and dry or the calibration will be incorrect. Never touch the membrane, as skin oil will affect the electrode response.6. Wait until the reading stabilizes then press and hold the CAL/RECALL button untilCAL is shown in the lower display. The readings will blink “101.7” and “SA” willappear.7. When the calibration is complete “End” will appear and then the meter will return tothe normal measurement mode.Note: The “SA” will not appear if the calibration fails.8. Optional ’zero oxygen’ calibration (improves measurement accuracy for very low orvery high DO measurements):Place the electrode in a zero oxygen calibration solution, such as 5% sodium sulfite,wait for stability and press the CAL/RECALL button until CAL is shown in the in thelower display. Stability in a zero solution may take many minutes, depending onelectrode history.Note: Sodium Sulfite can become deposited on the electrode and on the “coined”surface of the electrode retaining collar. The presence of the Sodium Sulfite willnegatively affect future DO measurements until such a time where ALL of it isremoved from the electrode.Measurement UnitsThe meter can be set to measure % saturation, dissolved oxygen in mg/l, and dissolved oxygen in parts per million (ppm). To change the mode:1. Press and hold the MODE/HOLD button for 2 seconds and the display will begin toscroll through the different units of measure :% saturation; D.O. in mg/l; D.O. in ppm (parts per million)2. When the desired units are displayed, release the MODE/HOLD button and the unitwill return to normal operating mode.Note: The “HOLD” function cannot be on when changing the measurement function. If “HOLD” is displayed in the lower left corner of the display, briefly press the MODE/HOLD button to turn it off.Temperature Units (ºF / ºC)1.

When “clr” is shown in the main display the memory is cleared.DO600-EU-EN-V7.0- 8/105DO600-EU-EN-V7.0- 8/106Measurement and Display Considerations•The DO600 uses a polarographic sensor, which consumes oxygen at the sensing surface. This requires a constant movement of the sample across the membrane to maintain a constant dissolved oxygen level. It is recommended that the probe be moved in the sample as the measurement is made, or if in a laboratory environment, the sample be stirred using a stir plate.•If the unit appears to be locked (display frozen). It is possible that the Data Hold mode has been inadvertently accessed by a press of the MODE/HOLD button (HOLD will be displayed in the bottom left of the LCD). Simply press the MODE/HOLD button again or turn the meter off and back on again.• If the meter does latch up and no button presses revive it, remove the batteries and restart.•For maximum accuracy, allow sufficient time for the temperature of the probe to reach the temperature of the sample before taking a reading. This will be indicated by a stable temperature reading on the display.MaintenanceBattery Replacement1. Twist off the battery compartment cover.2. Holding the battery housing in place with a finger, pull out the battery carrier using the two small tabs.3. Replace the four (4) CR2032 batteries observing proper polarity.4.Replace the battery carrier, reattach the battery compartment cap and tighten securely.You, as the end user, are legally bound (EU Battery ordinance ) to return all used batteries, disposal in the household garbage is prohibited! You can hand over your used batteries / accumulators at collection points in your community or wherever batteries / accumulators are sold!Disposal: Follow the valid legal stipulations in respect of the disposal of the device at the end of its lifecycleElectrode Replacement1. To remove the electrode, first turn the instrument OFF and then unscrew and remove the electrode retaining collar. (turn the collar counter-clockwise to remove).2. Gently rock the electrode from side to side, pulling it away from the meter until it disconnects.3.To attach an electrode, align the positioning “keys” on the electrode and the main body housing and then carefully push the electrode into the meter socket until it is fully seated.4.Tighten the electrode retaining collar firmly enough to seal the electrode with themeter.DO600-EU-EN-V7.0- 8/107DO Bonded Membrane Cap replacementImportant Note : Do not touch the membrane as skin oils will interfere with the oxygen permeability rate of the membrane. Use caution when replacing the bonded cap. 1. It is recommended that the electrode remain attached to the meter during thisreplacement process. 2. To remove the bonded cap from the electrode, unscrew the cap firmly and carefully counter-clockwise from the electrode (see diagram below).3.Discard the used cap. Please Note: The installation of a bonded cap causes the membrane to be tightly streched over the cathode. Once a bonded cap is removed reinstallation is not possible as the membrane will no longer be properly streched over the cathode.4. Rinse the old electrolyte solution from the Cathode and Anode before continuing.5.Use the supplied Polishing Strips to clean, polish, shine, and/or remove scratches from the cathode. Be sure to moisten the cloth before polishing the cathode. Do not over-polish the sensitive gold cathode.6. Set the new replacement bonded cap on a flat surface. Leave the cap in this position throughout the replacement process.7. Fill the bonded cap with the electrolyte solution up to the bottom of the threads on the inside of the cap.8. Tap the side of the bonded cap to help jar free any trapped air bubbles from the electrolyte solution.9.Keeping the cap in a fixed position on a flat surface, carefully insert the electrode into the new bonded cap by first dipping and removing the electrode several times from the cap. With each dip, push the electrode progressively deeper into the bonded cap. Finally, screw the electrode slowly onto the bonded cap (clockwise) until fully tightened. The dipping and removal technique minimizes the introduction of air bubbles into the electrolyte solution. Air bubbles in the electrolyte can compromise measurements.10. During the tightening of the bonded cap, excess electrolyte solution will leak out, thisis normal and desireable since it minimizes the introduction of air pockets. Clean off the excess electrolyte before use.CapVentsCAPCounter-clockwise to loosenSpecificationsDisplay 2000 count, Dual function 3 ½ digit LCD withBargraph,Display size: 24 mm x 20 mmSensor PolarographictypeMembrane Bonded membrane cap with threaded fittingOperating Temp.

溶解氧操作规程

溶解氧操作规程
二、操作步骤
1、
2、将DO探头的缆线连接头插入仪器顶部的输入端口。
将电源插头一端插入仪器顶部端口,一端插入230V,的电源插座。
3、校准100%:
打开源,使仪器处于测定状态,这时电极应套在护罩内进行校准,按cal键,连续按enter键四下,这时仪表会显示stabilizing并闪烁,当听到仪器“叮”的提示音后,仪器自动校准完毕。
二、维护和保养
1、该仪器设计成免维护的形式。如果仪器弄脏了,请用一块湿布擦拭表面。如果连接头弄湿了,请用棉签将其清洁并干燥。
2、DO探头维护:
每隔一定时间或当膜被破坏、被污染时需要更换膜盖并补充新的填充电解液(放在冰箱内保存)。如果膜未被损坏污染,建议更换电解质填充液的时间间隔为1—2个月。
3、在更换膜盖之前,用随电极附带的抹布擦拭阳极(探头的外侧金属杆,除去膜盖时可看到)。抹布可除去会降低探头操作性能的沉积物。如果经过一段时间后探头性能减退,则无论时更换膜盖时还是更换膜盖的间隙间均要擦拭阳极。
四、注意事项
1、DO电极仅用于液体。
2、在拿和存放氧气膜盖时一定要额外当心。
3、为了得到最佳操作性能,每天使用之前请进行校准,为了得到最大精度,请每隔两小时重新校准DO探头一次。
4、样品必须具有较高流速或被快速搅拌,以获得精确的测量结果。
5、确保读数之前驱除探头顶部夹带的任何气泡。
6、让探头保持恒定的温度非常重要。拿探头时不要触摸探头侧面的金属钮扣状物。该钮扣状物是用于感觉温度的热敏电阻。如果热敏电阻的温度与探头膜面的温度不同将会导致校准不精确。
4、将探头插入样品中至所需深度,探头必须插得足够深,使探头侧面的热敏电阻(金属钮扣状物)被淹没。
5、
6、在样品中搅动探头驱赶探头顶端敏感区存在的气泡。
