IoT digital residual chlorine sensor

Introduction

The online digital residual chlorine electrode adopts the constant voltage method, which can be equipped with a flow cell to monitor the residual chlorine content in the water body. The functions of automatic temperature compensation and digital signal conversion are realized inside the electrode. It has the characteristics of quick response, low maintenance cost, real-time online measurement and so on. The electrode adopts standard Modbus RTU (485) communication protocol, DC 24V power supply, four-wire mode, which can be easily connected to the sensor network.
