Introduction

This residual chlorine sensor is a three-electrode constant potential current measurement sensor that can be used to measure the concentration of residual chlorine, chlorine dioxide (high purity), ozone and other disinfectants. The sensor has a built-in ARM processor and efficient filtering algorithm, which can effectively avoid noise interference. It has an RS485 interface for easy access to computers and network monitoring systems. Widely used in tap water factory water, pipe network, secondary water supply, terminals, swimming pools and other scenarios.

Measuring principle

The film-free digital disinfectant sensor consists of two platinum electrodes and a silver chloride electrode forming a three-electrode measurement system. The electrodes have a built-in high-precision potentiostat, which can maintain the stability of the working electrode potential. Disinfectant components such as hypochlorous acid are oxidized at the working electrode. The reduction reaction produces an electric current that follows Faraday's law, thereby measuring the disinfectant concentration.
