Industrial NH3 Sensor Modbus RS485

The S-NH3-01 can measure the ammonia concentration, air temperature and humidity, and output the data through the RS485 Modbus RTU protocol. The sensor responds quickly, has anti-interference technology, and can be calibrated to ensure measurement accuracy. The equipment is powered by 5V DC, can be used with other equipment without complicated installation, and can easily be integrated into larger systems.

Applications include NH3 leakage detection. NH3 is produced by livestock farming industry.

Solid polymer electrochemical technology is a revolutionary innovation in the field of electrochemical detection. This technology is based on the principle of electrochemical catalytic reaction caused by the target gas leading to a electrical signal that is direct proportional to the gas concentration.
