NH3 transmitter uses a professional sensor of NH3 gas concentration sensor as the core detection device. It has the characteristics of a wide measuring range, high precision, good linearity, good versatility, ease to use, long-distance transmission, moderate price, and so on.

The transmitter adopts RS485 interface and standard MODBUS-RTU protocol, which can realize multi-point monitoring, networking and remote data transmission. Users only need to use any serial communication software to query and set module data according to the communication protocol.
It is suitable for various places, especially for public places, factories, warehouses and other places where ammonia gas monitoring is required.
