1. This sensor is different from other electrodes in the market, it is manufactured with Swiss cutting-edge technology, with silicon nitride covered photopolymer film and silicon crystal semiconductor as conduction components, built-in chlorine and temperature probe, and micro-electronic components are injected and packaged by MEMS technology. As the concentration of residual chlorine or chlorine dioxide in the water sample changes, the sensor generates different current intensity, which is processed by the regulator and signal amplifier, and converted into the standard MODBUS RS485 signal.
The use of the sensor does not need to change the reagent, simple maintenance, to ensure the long-term stability of the instrument reliability and accuracy. It can be used in waterworks, rural drinking water, water stations, secondary water supply and other fields.
