The RHC Relative Humidity Controller is our most recent development in total humidity control. It is switchable between humidify and dehumidify. The RHC has a built-in on board sensor which is accurate within +/- 5% with a set differential of 5%, and temperature compensation. Perfect for plant zone environments, reptile habitats, or just about any application requiring accurate response and control. 

The RHC-R is identical to the RHC, but offers a 20 ft. remote sensor.  Both units operate equipment up to 15 amps at 120 volt.
