Humidity & Temp Transmitters


Description  Features & Specifications
Humidity & Temp transmitters are designed for environment monitoring and controlling in industrial, commercial and other buildings. These transmitters can be used for indoor air temperature and humidity monitoring in various industrial plant, clean room, lab, machine room, commercial buildings, airport, and schools. The modbus interface is documented and integrator friendly. They also have transducer outputs for connecting as analog inputs to all popular control systems.
