Applications
H2,3 and 4 humidity and temperature transmitters are designed for environment monitoring and controlling in industrial and commercial buildings. Thesetransmitterscanbe used for:
Humidityandtemperaturemonitoringofsupply,exhaust and return air (H2, duct mount)
Humidityandtemperature monitoring in critical environment such as outside air(H3, outside mount)
Other applications of immersion humidity and temperature monitoring (H4, separate probe)
