Description

the advanced HVAC transmitter

Advantages in a glance

  • One or two selectable and scalable analog outputs
  • Analog outputs assignable to relative humidity, temperature or dew point
  • 2-wire or 3/4-wire systems available
  • Fast response and precision measurement With AirChip3000-technology

The new HygroFlex3-series is the latest development in HVAC transmitters for relative humidity, temperature and dew point. Based on AirChip3000 technology, the instruments achieve a degree of accuracy not seen before.

In combination with advances in sensor technology and integration, the HygroFlex3-series provides superb precision and state-of-the-art functionality, taking humidity, temperature and dew point measurement to a whole new level of performance and reliability (< 2 % rh / 0.3 K).
