The Eva-Dry EDH-1 Hygrometer Plug is designed to work with your dehumidifier or humidifier to monitor the relative humidity (RH%) of your room, control the power to the unit, and maintain the desired RH level.

To use, simply plug the EDH-1 into your wall outlet, then plug your dehumidifier or humidifier into the outlet on the front of the EDH-1. Using the controls, set the desired RH level between 30%-90% and the mode to humidify or dehumidify. The EDH-1 will turn the unit on or off to maintain your desired RH level.

The EDH-1 is the perfect enhancement to Eva-Dry's EDV-1100, EDV-2200, and EDV-2500 to customize your comfort experience.
