Digital Residual Chlorine Dissolved Ozone Chlorine Dioxide Sensor 9-36VDC

Constant Voltage Digital Residual Chlorine Dissolved Ozone Chlorine Dioxide Sensor

>>Overview

The instrument consists of signal measurement, processing, display, and panel controls. By applying a specific negative voltage amplitude between the polarized electrode and reference electrode, this device selectively allows residual chlorine, chlorine dioxide, and ozone concentrations to participate in the reaction. These substances undergo electrochemical reactions at the cathode of the electrode, generating current signals proportional to their respective concentrations. Through collection and analysis of these current signals, the instrument calculates the concentrations of residual chlorine, chlorine dioxide, and ozone. Key features include:

▪ High selectivity
▪ No replacement parts required
▪ Minimal maintenance
▪ Long electrode lifespan
▪ High reliability

This product is widely used in drinking water treatment plants, distribution networks, swimming pools, industrial wastewater systems, and cooling water circulation systems for continuous monitoring and control of residual chlorine, chlorine dioxide, and ozone levels in water.

>>Feature

▪ Digital sensor with RS-485 output, supports MODBUS
▪ Reagent-free operation, pollution-free, economical and environmentally friendly
▪ Constant voltage measurement with dual metal rings extends service life, accelerates response time, and ensures stable signals
▪ Electrode housing made of glass + POM material, withstands temperatures from 0 to 60°C
