Delta Ohm develop and manufacture a range of instruments for measuring humidity (and other parameters if required).

Transmitters and Regulators for Humidity
The HD45 and HD46 series are transmitters, indicators and controllers that measure and control, depending on the model, the following environmental parameters:

  • Relative humidity (RH)
  • Ambient temperature (T)
  • Carbon dioxide (CO2)
  • Dew point temperature (DP, calculated measurement)

They are suitable for monitoring the air quality in indoor environments. Typical applications include checking air quality in all buildings occupied by people (schools, hospitals, auditoria, work places, canteens, etc.).. This analysis allows the managing of conditioning plants (temperature and humidity)


Transmitters for Humidity
HD48 and HD49 series transmitters measure temperature, relative humidity and dew point. Versions with only standard analog output or with only RS485 output with MODBUS‑RTU protocol are available.
