Chloride ion online monitor

The chlorine ion online monitor consists of two parts: sensor and secondary meter. It can widely monitor the continuous monitoring of chloride ion concentration in water bodies such as lakes and rivers, surface water, water plants, sewage treatment plants, and wastewater discharged from enterprises. It provides a variety of common ion modes such as H+, Ag+, Na+, K+, NH4+, cl-, F-, NO3-, BF4-, CN-, Cu2+, Pb2+, etc., and supports user-defined ion modes to measure other ions. The corresponding ion electrode must be selected to measure the corresponding ion.

Main features

Chinese LCD display, Chinese menu, Chinese notes.

Microcomputerization: It adopts high-performance CPU chip, high-precision AD conversion technology and SMT patch technology to complete multi-parameter measurement, temperature compensation, instrument self-test, high precision and good repeatability. Quick response, accurate measurement and stable.

High reliability: single board structure, touch button, no switch knob and potentiometer.

Waterproof and dustproof design: protection level IP65, suitable for outdoor use.

Electromagnetic compatibility (EMC/RFI) design: designed and manufactured according to European standard EN50081/50082.

Alarm function: alarm signal isolation output, alarm upper and lower limits can be set arbitrarily, alarm hysteresis cancellation.

Historical curve: continuous recording of one month of data, one point every five minutes. Notepad function: record 200 messages.

Industrial control watchdog: ensure that the instrument will not crash. Password management: parameter setting and maintenance are password protected.

Offline measurement: replace laboratory sodium meter, standard liquid can be measured to check the performance of the instrument. Low cost of use and low maintenance.
