电导率仪使用说明书
原理电导率是以数字表示溶液传导电流的能力。
水的电导率与其所含无机酸、碱盐的量有一定的关系，当它们的浓度较低时，电导率随着浓度的增大而增加，因此，该指标常用于推测水中离子的总浓度或含盐量。
电导（G是电阻（R）的倒数。
因此当两个电极（通常为铂电极或铂黑电极）插入溶液中，可以测出两电极间的电阻R。
根据欧姆定律，温度一定时，这个电阻值与电极间距L（cm）正比，与电极的截面积A（cm2）反比，即八LR = ： - XA其中「为电阻率,是长1cm,截面积为1cmf导体的电阻，其大小决定于物质的本性。
据上式，导体的电导（G）可表示成下式：1 G=R 1 A 1 :—X 一=KX —PL J其中，K=1/ 称为电导率，J=L/A称为电极常数电解质溶液电导率指相距1cm的两平行电极间充以1cm3溶液时所具有的电导。
由上式可见，当已知电极常数（J ），并测出溶液电阻（R）或电导（G）时，即可求出电导率。
C0N-2A电导率仪的特点CON-2A型电导率仪是实验室测量水溶液电导率必备的仪器，它广泛应用于石油化工生物医药污水处理环境监测矿业冶炼以及大专院校和科研单位等。

电导率仪操作规程及使用过程中的注意事项
电导率仪操作规程及使用过程中的注意事项电导率仪主要是测液体介质之间传递电流能力的仪器，一般用于电力、化工、冶金、环保、制药、野外、湖泊、科研、食品和自来水等溶液中电导率值(TDS)的连续监测，同时在水处理，水产养殖试验方面也有应用。
一、人员该如何操作1、未开电源开关前，观察表针是否指零，可调正表头上的螺丝，使表针指零。
2、将校正测量开关扳在“校正”位置。
3、插接电源线，打开电源开关，并预热数分钟(待指针完全稳定下来为止)调节“调正”调节器使电表指示满度。
4、当使用(1)-(8)量程来测量电导率低于300μS.cm-1的液体时，选用“低周”，这时将高/低周开关扳向低周即可。
当使用(9)-(10)量程来测量电导率在300μS.cm-1至105μS.cm-1范围里的液体时，则将扳向“高周”。
5、将量程选择开关扳到所需要的测量范围，如预先不知被测溶液电导率大小，应先把其扳到最大电导率测量档，然后逐渐下降，以防表针打弯。
6、电极的使用：使用时用电极夹夹紧电极的胶木帽，并把电极夹固定在电极杆上。
(1)当被测溶液的电导率低于0.3μS.cm-1，使用DJS-0.1型电极，这时应把“电极常数补偿调节器”调节在所配套电极常数的10倍位置上：例如，配套电极常数为0.090，则应把其调节到0.90位置上。
(2)当被测溶液的电导率低于10μS.cm-1，使用DJS-0.1型电极，这时应把“电极常数补偿调节器”调节在所配套电极常数相对应位置上：例如，配套电极常数为0.95，则应把其调节到0.95位置上，又若配套电极常数为7、将电极插头插入电极插口内，旋紧插口上的紧固螺丝，再将电极綅入待测溶液中。
二、在操作过程中需要注意哪些1、在测量纯水或超纯水时，为了避免测量值的漂移现象，建议采用密封槽，在密封状态下的进行流动测量，如采用烧杯取样测量，则会产生较大的误差。
2、因温度补偿是采用固定的温度系数，所以，超、高纯水的测量，尽量采用温度不补偿方式进行，测量后查表。

The use of inductive sensors that are less sensitive to soiling than conductive sensors is recommended for high conductivity measurement, concentration measurement or adhering media.Measuring of conductivity and resistivity (conductive)This is selected via the menu. During measurement, the value measured can be displayed in the other measuring mode. The temperature is displayed at the same time or, if desired, not shown at all.Temperature compensationThe following temperature compensation selections are available: •Linear•NaCl curve according to IEC 746•Ultrapure water NaCl (neutral compensation)•Ultrapure water HCl (acid compensation, also ammonia)The reference temperature is user defined, the standard value is 25 °C (77 °F).ConfigurationDifferent alarms are required depending on application and operator. Therefore the transmitterpermits independent configuration of the alarm contact and error current for each individual error. Unnecessary or undesirable alarms can be suppressed in this manner. Up to four contacts Up to two contacts can be used as limit contacts (also for temperature), to implement a P(ID) controller or for cleaning functions.Direct manual operation of the contacts (bypassing the menu) provides quick access to limit, control or cleaning contacts, permitting speedy correction of deviations.The serial numbers of the instrument and modules and the order code can be called up on the display.The cell constant can be edited and even calibrated for demanding special applications.Additional functions of the plus packageCurrent output configurationIn order to output wide measuring ranges while still achieving a high resolution in specific ranges, the current output can be configured as required via a table. This permits bilinear or quasi-logarithmic curves, etc.Polarization detectionPolarization effects in the boundary layer between the sensor and the medium to be measured limit the measuring range of conductive conductivity sensors.The transmitter can detect polarization effects using an innovative, intelligent signal evaluation process.Live checkThe live check issues an alarm when the sensor signal does not change over a defined period of time. This may be caused by blocking, passivation, separation from the process, etc.Ultrapure water monitoring acc. to USP (United States Pharmacopeia) and EP (European Pharmacopoeia)Ultrapure water monitoring according to USP <645> and EP means that the uncompensated conductivity and the temperature are measured and compared to a table.The transmitter (conductive with additional contacts) comes with the following functions:•Monitoring of "Water for Injection" (WFI) according to USP and EP •Monitoring of "Highly Purified Water" (HPW) according to EP •Monitoring of "Purified Water" (PW) according to EPThe user-adjustable pre-alarm indicates undesirable operating values in due time. Full compliance with USP or EP requires the use of a precisely calibrated sensor, for example, the CLS16.Liquisys M CLM223/253Endress+Hauser 3Concentration measurementThe conversion from conductivity to concentration is effected using four user-definable concentration curves . This permits concentrations to be displayed in %, ppm, mg/l or TDS (total dissolved solids).Adaptive calibration for determination of the installation factor (inductive)Inductive measuring sensors must normally be installed in pipes at a required minimum distance from the pipe wall. If this minimum distance is not observed, the measured value changes. The built-in adaptive calibration using the installation factor allows you to compensate for this once the sensor is installed.Second current outputThe second current output can be configured for temperature, main measured value (conductivity, resistivity, concentration) or actuating variable.Current inputThe current input of the transmitter allows two different applications: controller shut-down in case of lower flow rate violation or total failure in the main flow as well as feedforward control.

TI193C/07/en/09.0551500279Technical InformationLiquisys M CLM223/253Conductivity/Resistivity MeasurementTransmitter for conductive and inductive sensorsApplicationThe modular design of the Liquisys M CLM223/253 allows easy adaption of the transmitter to a variety of customerrequirements. Starting with the basic version for "measurement and alarm generation", the transmitter can be equipped with additional software and hardware modules for specialapplications. These modules can also be retrofitted as required.Application•Ultrapure water •Water treatment•Ion exchanger, reverse osmosis •Cooling water desalinisationYour benefits•Field or panel-mounted housing •Universal application •Simple handling–Logically arranged menu structure –Ultrasimple two-point calibration •Safe operation–Overvoltage (lightning) protection–Direct access for manual contact control –User-defined alarm configurationThe basic unit can be extended with:•2 or 4 additional contacts for use as:–Limit contacts (also for temperature)–P(ID) controller–Timer for simple rinse processes–Complete cleaning with Chemoclean •Plus package:–User defined current output characteristics–Automatic cleaning trigger on alarm or limit violation –Ultrapure water monitoring acc. to USP (United States Pharmacopeia) and EP (European Pharmacopoeia) (conductive)–Polarisation detection (conductive)–Concentration measurement–Temperature compensation via table–Process Check System (PCS): live check of the sensor –Adaptive calibration with installation factor (inductive)•HART ® or PROFIBUS-PA/-DP•2nd current output for temperature, main measured value or actuating variable•Current input for flow rate monitoring with controller shut offor for feedforward controlLiquisys M CLM223/253Function and system designFeatures of the basic version Conductive or inductiveTwo instrument versions for measurement with conductive (two electrode) sensors or inductive sensors areavailable. The use of inductive sensors that are less sensitive to soiling than conductive sensors is recommendedfor high conductivity measurement, concentration measurement or adhering media.Measuring of conductivity and resistivity (conductive)This is selected via the menu. During measurement, the value measured can be displayed in the othermeasuring mode. The temperature is displayed at the same time or, if desired, not shown at all.Temperature compensationThe following temperature compensation selections are available:•Linear•NaCl curve according to IEC 746•Ultrapure water NaCl (neutral compensation)•Ultrapure water HCl (acid compensation, also ammonia)The reference temperature is user defined, the standard value is 25 °C (77 °F).ConfigurationDifferent alarms are required depending on application and operator. Therefore the transmitter permitsindependent configuration of the alarm contact and error current for each individual error. Unnecessaryor undesirable alarms can be suppressed in this manner. Up to four contacts can be used as limit contacts(also for temperature), to implement a P(ID) controller or for cleaning functions.Direct manual operation of the contacts (bypassing the menu) provides quick access to limit, control orcleaning contacts, permitting speedy correction of deviations.The serial numbers of the instrument and modules and the order code can be called up on the display.The cell constant can be edited and even calibrated for demanding special applications.Additional functions of the plus package Current output configurationIn order to output wide measuring ranges while still achieving a high resolution in specific ranges, the current output can be configured as required via a table. This permits bilinear or quasi-logarithmic curves, etc. Polarisation detectionPolarisation effects in the boundary layer between the sensor and the medium to be measured limit the measuring range of conductive conductivity sensors.The transmitter can detect polarisation effects using an innovative, intelligent signal evaluation process. Process Check System (PCS)This function checks the measuring signal for stagnation. If the measuring signal does not change for some time (several measured values), an alarm is triggered. Soiling, blockage or similar could be the cause of such behaviour.Ultrapure water monitoring acc. to USP (United States Pharmacopeia) and EP (European Pharmacopoeia)Ultrapure water monitoring according to USP <645> and EP means that the uncompensated conductivity and the temperature are measured and compared to a table.The transmitter (conductive with additional contacts) comes with the following functions:•Monitoring of "Water for Injection" (WFI) according to USP and EP•Monitoring of "Highliy Purified Water" (HPW) according to EP•Monitoring of "Purified Water" (PW) according to EPThe user-adjustable pre-alarm indicates undesirable operating values in due time. Full compliance with USP or EP requires the use of a precisely calibrated sensor, for example, the CLS16.Liquisys M CLM223/253Concentration measuringThe conversion from conductivity to concentration is effected using four user-definable concentration curves . This permits concentrations to be displayed in %, ppm, mg/l or TDS (total dissolved solids).Adaptive calibration for determination of the installation factor (inductive)Inductive measuring sensors must normally be installed in pipes at a required minimum distance from the pipe wall. If this minimum distance is not observed, the measured value changes. The built-in adaptive calibration using the installation factor allows you to compensate for this once the sensor is installed.Second current outputThe second current output can be configured for temperature, main measured value (conductivity, resistivity, concentration) or actuating variable.Current inputThe current input of the transmitter allows two different applications: controller shut-down in case of lower flow rate violation or total failure in the main flow as well as feedforward control.
