Applications :
H2, H3, and H4 humidity and temperature transmitters are designed for environmental monitoring and controlling in industrial and commercial buildings. These transmitters can be used for:
|
Humidity and temperature monitoring of supply, exhaust and return air (H2, duct mount) |
|
Humidity and temperature monitoring in the critical environment such as outside air (H3, outside mount) |
|
Other applications of immersion humidity and temperature monitoring (H4, separate probe) |
