FREE CHLORINE SENSOR, CHLORINE DIOXIDE SENSOR

This sensor is different from traditional electrodes. It is manufactured with cutting-edge Swiss technology, using silicon nitride-coated photopolymer films and silicon crystal semiconductors as conductive elements. It has built-in chlorine and temperature probes.

Through MEMS technology, microelectronic components are injection-molded and encapsulated.

As the free chlorine or chlorine dioxide concentration in the water sample changes,the sensorgenerates

different current intensities, which are processed by a regulator and signal amplifier, and converted into standard Modbus RS485 signals.

The sensor does not require the replacement of reagents during use, and is easy to maintain, ensuring the stability, reliability, and accuracy of the instrument's long-term operation. It can be used in water plants, rural drinking water, water stations, secondary water supply, and other fields.
