Duct Mount/Outside Air/Remote MountTemperature & Humidity Transmitter

H2, 3 and 4 humidity and temperature transmitters are HAVC sensors

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

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)
