In fact a female affair ...

is the donation of choice natural hair for use as a humidity measuring element. The resulting manually adjusted sensitive natural hair grid has been employed for decades outdoors or when high accuracy is required. The precision mechanics meter drives the recording drum (acc. to DIN 58658), on which the special smear-proof charts are mounted. The even draft of curves as a continuous recording of relative humidity is written by a felt pen.

  • independant of mains power
  • very low maintenance
  • very robust (metal housing)
  • long-term and stable measuring element
  • hygro-mechanic, recording
  • easy reading and handling
  • large temperature application range
