New: Mechanical hygrostat

MFR 012

The hygrostat is used to prevent condensate and regulates heating and fans. From a critical relative air humidity of 65 %, the temperature is increased so that the dew point is raised.

  • Adjustable relative air humidity
  • Changeover contact (heating or cooling)
  • High switching capacity
  • Clip mounting
