Humidity Switches

Our humidity switches offer control for the humidifying and dehumidifying systems that are of critical importance to labs, industrial environments, workplaces and museums. A switch can display and control humidity within spaces ranging from environmental chambers to refrigerated vehicles. It can report relative humidity, output status, and error messaging information.  By setting available parameters, you can use a switch to define setpoint, hysteresis, control type, and cycle time, as you accurately monitor humidity.  Our humidity control switches work with compatible probes and are provided by product innovators, such as Dwyer Instruments.
