Welcome to buy high quality rs485 modbus residual chlorine sensor in stock here from our factory. If you have any enquiry about customized service, please feel free to email us.
Product Features:
1. We use electronic and chemical sensors, there is no reagent consumption and pollutant emissions;
It is designed without film. So there is no need to replace the membrane head and adding electrolyte;
We designed three electrodes, there are zero point stability and high sensitivity;
The built-in high-precision sampling circuit makes the sensor linearity good;
5. When the pH does not change much, it can be accurately compared with the DPD measurement method.
