Humidity & temperature sensor

Humidity & temperature sensor

Typical applications include:
  • Pharmaceutical facilities
  • Laboratories
  • Hospitals
  • Indoor swimming-pools
  • Computer and data processing centers
  • Greenhouses


QFA3100 and QFA4100 Series sensors are used in HVAC systems where high accuracy and short response times for measuring relative humidity are required. The sensors maintain a +/- 2% RH accuracy from 0 to 100% RH.

Sensors are available with either 0 to 10V or 4 to 20 mA output signals. Options include an LCD display and additional analog output for temperature.
The QFA3100 Series sensors feature an enclosure with gaskets and may be installed outdoors with an AQF3100 weather shield (sold separately).
