Digital Residual Chlorine Sensor with Modbus485 Chlorine Probe Water Analyzer

Measurement Principle
The PDCL-400A digital residual chlorine/chlorine dioxide sensor uses advanced constant voltage principles to measure residual chlorine/chlorine dioxide in water. The method utilizes a stable potential between the polarized electrode and the reference electrode at which different measured components produce different current intensities. The meter calculates the concentration of the measured component by collecting and analyzing the current signal.
The PDCL-400A digital residual chlorine/chlorine dioxide sensor is simple in structure, easy to clean and replace, and requires no membranes and reagents to replace the electrode during maintenance.

n  Features

u  Easy clean and replace.

u  Electrode no need to replace membrane and reagent when operating and the maintenance is simple to ensure the stability,reliability and accuracy of instrument for long-term working.

u  Power supply and output isolation design to ensure electrical safety

u   Power supply and communication chip built-in protection circuit, strong anti-interference ability

u  With a comprehensive protection circuit design, it can work reliably without additional isolation equipment

u  The circuit is built in the inside of the electrode, the environment is well tolerated, and the installation operation is easier.

u  RS-485 transmission interface, MODBUS-RTU communication protocol, two-way communication, can receive remote commands

u  Communication protocol is simple and practical, extremely convenient to use

u  Output more electrode diagnostic information, more intelligent

u  Internal integrated memory, memory calibration and setting information can be memorized after power off
