The RFHSS Electromechanical Hygrostat is designed to control the relative humidity inside of electronic enclosures. When connected to an enclosure heater or dehumidifier, it will switch on the heater at the humidity set point in order to raise the dew point. This helps prevent damage and malfunction of electronic components and metal parts caused by condensation and corrosion.

The RFHSS series can also be used to control cooling fans, warning lights, or other devices and is equipped with a negative feedback contact, which could be used as a dry contact for centralized monitoring and controlling systems (PLC).
