▎Product Introduction ：
RLH-100 Series High-Temperature Humidity Transmitter is a humidity detection device transmitter developed and manufactured by our company, designed for harsh environments. The system is highly integrated with a built-in precision optical sensor. When the measured gas enters the sampling chamber of the sensor, the water vapor within absorbs laser light of a specific wavelength. The sensor amplifies and converts this change into a standard signal, which is then processed by a microprocessor and provided to users for data interaction via RS-485 digital signals and 4-20mA analog signals.
This transmitter is primarily used in industrial steam-related applications, high-temperature sterilization processes, constant-temperature chambers, and other high-temperature humidity environments.
▎Key Features ：
1.Capable of long-term operation within a working temperature range of (-20~+200)°C.
2.Resistant to corrosive measurement environments.
3.Strong anti-interference capability, avoiding gas cross-interference.
4.Long service life with excellent long-term stability.
