Adjustable and pre-set relative humidityOptical operating display(LED)High switching capacityClip 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 intergrated in the adjustment knob is lit when the connected heater is in operation.
