The electronic hygrotherm senses the
ambient temperature and relative humidity in
an enclosure with electric/electronic
components, and turns on a heater (or
alternatively, a fan) at either set point,
helping prevent the formation of
condensation in the enclosure. The LED
integrated in the adjustment knob on the
active controller is lit when the connected
device is in operation.
