盐水电解质检测仪说明书

盐水电解质检测仪说明书

Free Chlorine Amperometric 4-20mA SensorsSECTION 1THEORY OF OPERATION1.0 FREE CHLORINE DEFINED. Free Chlorine or "freely active chlorine" is defined as the sum of molecular chlorine (Cl 2), hypochlorous acid (HOCl) and hypochlorite ions (OCl -). Molecular chlorine occurs at pH values <pH4. Hypochlorus acid and hypochlorite ions are in pH de-pendent equilibrium with one another as shown in FIG 1. The graph shows % hypochlorous acid on the left of the curve. Hypochlorous acid is a much stronger disinfecting agent (oxidizer) as compared to hypochlorite ions.1.2 SENSOR OPERATING PRINCIPLE. Only hypochlorous acid (HOCl) diffuses through the membrane between the cathode and sample solution. At the applied potential, only hyphochlorous acid is elec-trochemically reduced. HOCl is reduced to chloride ion at the gold cathode. At the same time, the silver anode is oxidized to form silver chloride (AgCl). When the concentration of HOCl at the cathode is dramatically decreased by electrochemical reduction, hypochlorite ion will be transformed into hypochlorous acid , to some extent, by proton transfer. The release of electrons at the cathode and ac-ceptance at the anode creates a current flow, which under constant conditions, is proportional to the free chlorine concentration in the medium outside the sensor. The resulting low current output is then conditioned to 4-20mA current by the sensor's onboard electronic circuitry.SECTION 2FACTORS INFLUENCING THE SENSOR2.0 pH. Free Chlorine (FCL) exists as hypochlorous acid andhypochlorite anion (FIG 1). The acid-base dissociation of FCL has a pKa of approximately 7.5. The FCL sensor responds to hypochlorous acid and hypochlorite anion with different sensitivity. In combination, an increase in pH reduces the measured FCL and decrease in pH increas-es the measured FCL. For the most accurate free chlorine measure-ment, pH compensation is required above pH 6.5. pH compensation for the sensors current (mA) reading is:Real mA = (measured mA – 4)/ compensation factor + 4compensation factor = -0.13*pH*pH + 1.6718*pH - 4.15672.1 Chemical Interferences. The sensors should not be used in water containing surfactants, organic chlorine or stabilizers such as cyanuric acid, chlorine dioxide, ozone or bromine.2.2 FLOW. To acheive reproducible measurements, the (FCL) free chlo-rine sensors require a specified constant flow rate. To avoid complica-tions (such as bubbles), it is best to operate the sensors at a flow rate of 0.2-0.6 gpm ( if using flow cell FC72 or FC70 (old version). Use of a flowmeter is recommended ( FM001- See Section 4.1)SECTION 3SENSOR PREPARATION3.0 FREE CHLORINE SENSOR ASSEMBLY. The Free Chlorine Sensor is shipped with the membrane cap pre-installed andcovered with a cap with water inside to keep the membrane wet. Make sure to keep sensor cap, anode and cathode, away oily or greasy materials. Contact with oil or grease will result in inaccurate measurements. The sensor is also supplied with a 3 oz bottle of refill solution and a syringe and needle tip.NOTE: IF SENSOR WILL BE STORED DRY OUT OF THE FLOW CELL, SHAKE BODY DOWNWARD INTO A SINK TO REMOVE THE FILL SOLUTION. TAKE THE MEMBRANE CAP AND IMMERSE IT IN A CUP OF TAP WATER UNTILL READY TO REUSE. SEE SECTION 10. REPLACE CAP AND ELECTROLYTE BEFORE INSTALLING INTO FLOW CELL (see SECTION 10 for cap and electrolyte change. See SECTION 5 for sensor installation into flow cell).SECTION 4FLOW CELL /FLOW SENSORINSTALLATION4.0 FLOW CELL. To obtain accurate Free Chlorine reading, the Sensor must be installed into the Flow Cell to prevent air bubbles formation on the membrane, proper spacing between the sensor and the installation wall, and laminar flow across the membrane. MAKE SURE SENSOR AND FLOW CELL ARE ORIENTED VERTICALLY OR NO MORE THAN 45 DEG BELOW VERTICAL (FIGURE 2B)4.01. Using two 1/4” NPT Tube fittings, connect the FC72 Flow Cell into your system, noting the inlet (bottom) and outlet (side) orientation. (see FIGURE 2)4.02. Install clamp with rubber backing as shown in FIG. 2A.4.03 Drill 3/8" diameter hole on the panel.4.04 Insert bolt as shown in FIG 2A4.05 On back of panel attach lock washer and nut to secure clamp and flow cell to panel.Ensure flow cell is mounted at 45 deg or higher above horizon-tal as shown in FIG 2b.4.1 FLOW METER. To control flow to the flow cell, a flow meter is recommended. Sensorex supplies model FM001 for this purpose. The FM001provides flow control from 0.1 to 1.0 GPM (0.5 to 4.0 LPM) with 6% accuracy.4.1.1 Install the flow meter and flow cell as shown in FIG 2c. Follow the diagram so that the incoming water is attached to the bottom of the flow meter (where flow adjustment knob is located).6.0 ELECTRICAL INSTALLATION. The sensor produces an ap-proximate output of 4 mA in air and 20mA at the top range of free chlorine output (0-2ppm, 0-5ppm, 0-10ppm).NOTE: The supply voltage to the Sensor must be 12-24 V DC withminimum of 250 mA. Maximum load is 1 Watt. The sensor has 3 wires, red (+) , black (-) and clear (shield). Twist together or solder black and clear if instrument does not have separate ground. If a separate ground is available such as for PLC’s connect clear (shield) to it.Attach the red wire to the power supply positive terminal (+)and the black wire to the PLC or DVM positive (+) terminal. Connect a wire (customer supplied) from the power suppy negative (-) and the PLC or DVM (-). See FIG 3. The Sensor will require several minutes to stabilize after power is supplied to it.7.0 SENSOR CONDITIONING The sensor requires conditioning prior to generating stable values. a. For new Sensors, connect the sensor to power and allowto run overnight (at least 12 hours) before calibration. b. If the Sensor will be un-powered for 2 hours or more, run for 2 hours prior to use. c. If the Sensor's flow will be off for 1 hour or less, run the sensor for at least 1 hour prior to recalibration. c. After membrane/electrolyte replacement, allow the Sensor to run powered overnight (at least 12 hours) before calibration .SECTION 6ELECTRICAL INSTALLATIONSECTION 7SENSOR CONDITIONINGSECTION 5SENSOR INSTALLATION5.0 SENSOR INSTALLATION INTO FLOW CELL. a. First install threaded fitting onto sensor body (remove fitting if pre-installed in flow cell) b. Install snap-ring into groove on sensor body c. Next, slide o-ring onto body of sensor until it reaches bottom of threaded fitting. d. Thread sensor assembly into top of flow cell as shown in FIGURE 2. d. Turn on flow and verify the flow through the Flow Cell is at least 0.2gpm (45 liters/hour and no more than 0.6gpm (135 liters/hour).10.0 ELECTROLYTE SOLUTION REPLACEMENT: Drain and refill the sensor approximately every 2 months.10.1 MEMBRANE CAP REPLACEMENT. If membrane replacement is required, a new cap with preinstalled membrane must be used. Order FCLA-4016 replacement membrane cap and FCLA-4015 refill solution. To change membrane cap (do the following over a sink or washbasin):a) turn sensor upside down with cap facing upward b) rotate cap counter-clockwise to remove (see FIG 10).c) Attached supplied needle to syringe and remove fill solution as shown in FIG 10 & FIG 11.c) fill sensor body with electrolyte using needle and syringe of refill solution (see FIG. 12)d) install a new membrane cap by threading cap onto sensor rotating cap clockwise (opposite of FIG 9)10.2 MEMBRANE CAP/SENSOR CLEANING. Rinse cap with water only. If cap does not clean, replace with new one.SECTION 10SENSOR MAINTENANCE/RECONDITIONINGSECTION 11SENSOR TROUBLESHOOTING11.0 CALIBRATION PROBLEMS a) Sensor output HIGHER than DPD test 1) Run in time too short 2) Membrane cap damaged 3) Interference from water contaminants (see Specifications, "Cross Sensitivity") 4) Cable short circuit or damage 5) pH value less than pH 5.5 b) Sensor output LOWER than DPD test 1) Run in time too short 2) Deposits on Membrane cap 3) Flow rate too low 4) Air bubbles on membrane 5) Surfactants in water 6) pH value more than pH 8.57) no electrolyte in sensor chamberc) Sensor ouput is 4mA (zero ppm) 1) Run in time too short 2) Only bound chlorine present 3) Chlorine content below detection limit 4) Sensor not wired correctly (See SECTION 6.0 of this manual) 5) Defective sensor d) Sensor output UNSTABLE 1) Air bubbles on membrane 2) Membrane damage 3) Pressure fluctuation in sample lineSymptom Possible CauseSolution/Remedy The sensor 1) Run in time too short1) See Sec 7.0 -CONDITIONINGcannot be 2) Membrane cap damaged2) Replace cap - See Sec 10.0 calibrated- 3) Interference from contaminants 3) See SPECIFICATIONS Sec 12 ouput is 4) DPD chemicals bad 4) Use new DPD kitHIGHER than 5) pH value < pH 5.5 5) Increase pH (5.5-8.5) DPD TestSee SPECIFICATIONS Sec 12 6)Temperatue increased since cal6) Match calibration temp.The sensor 1) Run in time too short 1) See Sec 7.0 -CONDITIONING cannot be 2) Deposits on membrane cap 2) Remove deposits or replace calibrated- cap if cleaning ineffective. output is 3) Flow rate too low 3) increase fl ow - See LOWER than SPECIFICATIONS DPD Test 4) Air bubbles on membrane 4) Remove and re-install s ensor to remove bubbles. 5) Surfactants in water 5) Remove surfactants and replace cap.

BY2010智能盐密度测试仪新型使用说明书

BY2010智能盐密度测试仪新型使用说明书

BY2010智能盐密度测试仪(新型)使用说明书引言欢迎使用直读式等值盐密度测试仪(盐密仪)我们在设计建造输送容量大的电站和线路前应首先测定外绝缘的饱和盐密度以确定所在区域的污秽等级,选择合适的外绝缘爬电比距,使污闪事故率降低到本电力系统安全经济送电可以接受的程度(即可接受的污闪事故率),让国民经济损失降低到最少。

我国电力系统一般网架比较薄弱,多次污闪跳闸即有可能带来整个系统瓦解,引起大面积停电,某些污闪事故停电及检修时停电带来少送电量引起的损失,远远超过基建时外绝缘的投资。

污闪事故不同于一般单纯的设备事故,它涉及面广、影响设备多且分散,往往造成大面积、多设备的连锁事故。

对于已经投入使用高压输电线路、发电厂、变电站等场所的外绝缘设备应当每年至少检测一次其表面污秽程度,以衡量是否可能引起污闪事故。

作为判断外绝缘设备是否需要清洗或更换的依据。

我公司根据电力行业防治污闪的要求,针对进口电导仪器不能直接读出盐密度值的弊端,以及其对绝缘子盐密测试的不适应性,开发了最适合用户需求的BY2010绝缘子直读式等值盐密度测试仪,操作简单、功能齐全,得到了行业客户的一致认可。

土壤盐分测量仪使用说明及操作方法

土壤盐分测量仪使用说明及操作方法

土壤盐分测量仪使用说明及操作方法土壤盐分测量仪使用说明及操作方法我们都知道这样一个道理,那就是植物只有在合适的条件下,才会生长良好。

这里说的条件可能是环境条件、土壤条件等,因此只要不满足了,那么很有可能就会对植物的生长造成损害,以土壤盐分为例,土壤中过多的盐分会阻碍植物正常生长发育,进而致使其品质变劣、产量降低。

因此在农业生产中,使用土壤盐分测量仪测量土壤盐分已经成为高品质栽培中的一项重要内容。

农业领域为什么要使用土壤盐分测量仪测量土壤盐分?主要还是因为土壤盐分超标会给植物生长造成影响,造成土壤盐分胁迫,因此在解答这个问题之前,不妨让我们看看土壤盐分胁迫对植物的伤害都有哪些?1.影响作物的光合作用:在土壤盐分胁迫下,植物会因为吸收不到足够的水分和矿质营养,从而造成营养不良,致使叶绿素含量低,影响光合作用。

2.影响作物的呼吸作用一般来说,盐分过多时总的趋势是呼吸消耗量多,净光合生产率低,不利于植物生长。

3.对植物细胞膜结构的影响土壤盐分胁迫会直接影响细胞的膜脂和膜蛋白,使脂膜透性增大和膜脂过氧化,从而影响膜的正常生理功能。

4.阻碍农作物蛋白质合成土壤盐分过多对蛋白质代谢影响比较明显,会抑制合成促进分解,从而使蛋白质含量减少。

另外还会使作物产生有毒物质,致使植物叶片生长不良,抑制根系生长,组织变黑坏死等。

由此可见,土壤盐分胁迫对于植物的伤害是不容忽视的,而由于过去不过范的化肥和农药的滥用,导致我国的耕地或多或少都存在土壤盐分超标的现象,因此要开展绿色无公害种植,高产农田种植,那么首先要做的就是使用土壤盐分测量仪来测量土壤盐分,进而指导科学改良措施的制定和开展,培育出优良的土壤环境,这样才能够真正实现农业的高质高产目标。

托普云农土壤盐分测量仪主要用于农业生产过程中各种土壤,水培养基质的盐分含量测量。
