H2, 3 and 4 humidity and temperature transmitters are HAVC sensors
Applications
H2, 3 and 4 humidity and temperature transmitters are designed for environment 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 critical environment such as outside air (H3, outside mount)
Other applications of immersion humidity and temperature monitoring (H4, separate probe)
Features
High performance digital sensors and circuits, ensure accurate measurement and temperature compensation
Good long term stability and reliability
100% field changeable sensors, no re-calibration needed
Fast response
Multiple output signals selectable
Industrial design, SS probe and selectable filter
High protection rate up to IP65
