remote mount humidity and temperature transmitter with LCD display

Applications & 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
