Temperature & Humidity Transmitter

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 temperaturemonitoring in critical environment such as outside air (H3, outside mount) Other applications of immersion humidity and temperature monitoring(H4, separate probe) FeaturesHigh 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.
