Applications:
H2,3,4 humidity and temperature transmitters are designed for environment monitoring and controlling in industrial, commercial and other buildings. These transmitters can be
used for:
Humidity and temperature monitoring of supply, exhaust
and return air(H2, duct mount)
Humidity and temperature monitering 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 sintered filter
High protection rate to IP65
