Duct/Outdoor Temperature & Humidity Transmitter Model H2, 3, 4N
Application and Features
-
Humidity and temperature transmitters H2N (duct), H3N (outside) and H4N (remote) are designed for environment monitoring and controlling in industrial and commercial buildings
-
High performance digital sensors and circuits, ensure accurate measurement and temperature compensation
-
Digital technology applied, multiple outputs optional, over voltage and reverse polarity protection, high reliability and anti-interference capability
-
LCD display temperature and humidity alternatively
-
LCD & function keys can set parameters and calibrate output, so the product can be a stand alone controller
-
Good long term stability and reliability
-
100% field changeable sensor without re-calibration
-
Fast response
-
High protection rate up to IP65
