Residual chlorine controller/transmitter

The residual chlorine controller/transmitter with pH compensation affects the form of chlorine in water. Reliable residual chlorine measurement must include pH and temperature compensation. Suitable for various occasions where residual chlorine is precisely controlled. Configure a membrane free three electrode residual chlorine electrode for precise measurement. Can be compared to DPD. ● IP65 protection level for the entire machine; Backlight illumination, suitable for harsh usage environments. ● Use integrated switch power modules to further improve the stability and anti-interference ability of the instrument. A concise and clear human-machine interface makes operation more convenient and user-friendly. ● Password protected, important setting parameters will not be modified incorrectly. The set parameters can be browsed in real-time in measurement mode, allowing you to keep track of the working status at any time. Two independently adjustable relays meet the precise control needs of users, with arbitrary delay bandwidth settings. ● Third channel cleaning/alarm function relay: Users can set the cleaning frequency and time themselves. Multiple current output options: 0/4-20mA, with a customizable range for users to record or remotely transmit measurement values. ● Temperature reading offset adjustment: Compare the actual verification values on site to reduce measurement reading errors.
