The Teren H4N is a remote-mounted transmitter designed for humidity and temperature measurement in industrial and commercial buildings, used for environment monitoring and controlling. 

It employs high-performance capacitive polymer digital sensors and circuitry to ensure accurate measurement and temperature compensation. 

The H4N features an optional LCD and functions to display temperature and humidity, and enable users to set parameters and calibrate the output.

The standard model offered uses a 2% accuracy sensor and includes the temperature output. 


Key Features

  • High protection rate up to IP65.
  • High-performance digital sensors and circuits for accurate measurement and temperature compensation.
  • Capacitive polymer sensing technology with good long-term stability fast measurement response.
  • Flexible output options (mA, Vdc, modbus, relay). 
  • Optional LCD and function keys for parameter setting and output calibration 

Important Notes:

  • H2,3,4N series current products are powered by RH circuit, so the RH circuit must be powered. Otherwise, it could not work.
  • Only when the temperature output is 1 or 2, the temperature range 1-7 is applicable. Otherwise, always use 0 as temperature range selection.
