The KSMH is 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 set humidity level in order to raise the dew point. This helps prevent
damage and malfunction of electronic components caused by condensation and corrosion.*
The KSMH can also be used to control cooling fans, warning lights or other devices.
