  • Adjustable and pre-set relative humidity
  • Status indicator (LED)
  • High switching capacity
  • Clip fixing
  • Temperature-compensated

The electronic hygrostat senses the relative humidity in an enclosure with electric/electronic components and turns on a heater at the set point, helping prevent the formation of condensation in the enclosure. The LED integrated in the adjustment knob is lit when the connected heater is in operation.
