Mechanical Hygrostat

The KSMH50 and KSMH65 have been designed to control the relative air humidity inside of enclosures. When connected to an enclosure heater, (de-humidifier), it will turn the heater on at the preset humidity setpoint in order to raise the dew point. This helps prevent damage and malfunction of electronic components caused by condensation and corrosion. These units can also be used to control cooling fans, warning lights or other devices.
