Humidity Controller

Humidity Controller OJ Electronics is a global supplier of thermostats, power controls, HVAC supplies and much more

EHP is a series of controllers for regulating air humidity on the basis of a signal received from an air humidity transmitter. The EHP series is ideal where a signal is required to an air humidifier/dehumidifier in order to raise or lower the existing level. The EHP takes up little space and is installed on a DIN-rail in an electrical panel together with other control devices.

The EHP controller is designed to provide our customers with an advantageous combination of high quality, precise control and low lifecycle costs.
