Digital Residual Chlorine Sensor
BH-485-CL
The digital residual chlorine sensor is a new generation of intelligent water quality detection digital sensor independently developed by BOQU Instrument. Adopt advanced non-membrane constant voltage residual chlorine sensor, no need to change diaphragm and medicine, stable performance, simple maintenance. It has the characteristics of high sensitivity, fast response, accurate measurement, high stability, superior repeatability, easy maintenance, and multi-function. It can accurately measure the residual chlorine value in solution. It is widely used in self-controlled dosing of circulating water, chlorine control in swimming pools, and continuous monitoring and control of residual chlorine content in aqueous solutions in drinking water treatment plants, drinking water distribution networks, swimming pools, hospital waste water, and water quality treatment projects
Technical Features
1. The residual chlorine digital sensor is directly output RS485 signal
2. High precision, high stability and strong anti-interference ability
3. No instrument required, can be directly connected to computers, PLC and other equipment with RS485 signal interface for data collection and maintenance;
4. It is convenient for users to integrate sensors into industrial control environments such as host computer systems and things.
5. Relevant settings can be set for the sensor through RS485 communication, slave address and baud rate, online calibration, factory reset, , scale factor and incremental compensation and other settings.
6. Adopt two-point correction method.
