Product Description

The HygroFlex5 Series offers you ultimate performance and flexibility thanks to its interchangeable HygroClip2 probes. The transmitters come in wall and duct mount versions. Many useful functions can be accessed with optional HW4 software. HF5-Series is available with analog and digital outputs, so compatibilty with almost any monitoring or control system is assured. Digital versions may be networked togther to form a dedicated environmental monitoring system using HW4 software. The new generation device not only has a unique calibration and adjustment process, but also allows probes to be interchanged in just a few seconds. This easy interchangeability during operation reduces down-time and service costs to a huge extent. The possibility of using every probe as a simulator with fixed output values is a big advantage for system validation. In the case of networked devices this can even be carried out online from a remote PC workstation.


  • High specification HVAC applications, building management systems, museums, libraries, environmental monitoring systems.

Highlights :

  • Unique calibration and adjustment process
  • Highest reproducibility
  • Wall and duct versions; the wall version also serves for the connection of cable based probes
  • Many useful functions can be activated with the optional HW4 software
