Description
TRH-403 is not just a standard display-type thermo-hygrometer, but an industrial-grade temperature and humidity transmitter that can be directly integrated into automation and monitoring systems. In addition to simultaneously measuring temperature, humidity, and dew point, it can also transmit data in real time to PLCs, display boards, or backend systems via 4 ~ 20mA, 0 ~ 10V, and Modbus RS-485, making it ideal for environments requiring long-term stable monitoring and remote management.
The product features high-precision sensing, a large LCD display, and alarm control output. It can be used together with dehumidification, air conditioning, ventilation, and temperature control equipment for automatic control, greatly improving environmental management efficiency. It is widely used in factories, server rooms, warehousing, biotechnology, agriculture, laboratories, and smart buildings.
