Product introduction

The residual chlorine digital sensor is a new generation of intelligent water quality detection digital sensor independently developed by our company, and has patented technology. The advanced non membrane constant voltage sensor is adopted, without replacing the membrane and reagent, with stable performance and simple maintenance. Data can be viewed, debugged, maintained, etc. through mobile phone APP or computer. It has the characteristics of high sensitivity, rapid response, accurate measurement, high stability, excellent repeatability, simple maintenance, multi-function, etc. It can accurately measure the residual chlorine value in the solution.

It is widely used for automatic dosing of circulating water, chlorination control of swimming pools, continuous monitoring and control of residual chlorine content in water solutions in drinking water treatment plants, drinking water distribution networks, swimming pools, hospital wastewater, water quality treatment projects, etc.

main features

◇ This product is a residual chlorine digital sensor, which can directly output RS485 signal and 4~20mA signal

◇ The product has high precision, high stability and strong anti-interference ability

◇ Without instrument, it can directly connect computer, PLC and other equipment with RS485/4-20mA signal interface for data acquisition and maintenance; It is convenient for users to integrate the sensor into the host computer system and the industrial control environment such as the Internet of Things.

◇ Use mobile phone APP to collect, debug and maintain data of sensors through wired (OTG cable and 485 to USB module) or wireless networks (such as WIFI, GPRS and other wireless networks).

◇ The sensor can be set through RS485 communication, such as slave address and baud rate, online calibration, factory restoration, 4-20mA output corresponding range, proportional coefficient and incremental compensation. Without instrument, it can be directly connected to computer, PLC and other equipment with RS485/4-20mA signal interface for data acquisition. It is convenient for users to integrate sensors into industrial control environments such as host computer system and IoT system.

◇ The probe can be replaced.

◇ Two point correction method is adopted.

◇ The core components are from foreign brands.
