As the humidity thanks to little helper is kept constant at a level humidity control are used in many areas since the relative humidity as well as temperature plays an important role when it comes to air quality. The man feels about 45% to 55% relative humidity, a humidity control in offices and living rooms makes for pleasant conditions. But, materials used in the industry to respond to too high or too low values of the humidity. A wide range of humidity controls has added to its range the PCE Germany GmbH. Metal not rust, preserved food, or, for example, exhibits in museums not mouldy, humidity control are used. Also used in greenhouses, factories and in the pharmaceutical industry. Learn more about this with Cecilia Shen. As a humidity regulator requires an analog signal of the norm, a humidity transmitters is upstream, which takes the current air humidity and transforms.
In advance the operating personnel can set target values in their under – or overrun the controller takes up his work and compares the value.

The air humidity is too low, the humidity controller starts a humidifier to increase the humidity again. Largely a humidity control is set front with buttons, in addition it is possible to connect the controller to the PC if there is a digital interface. As examples, 15 or the PCE-RE 22 can be in addition to the PCE RE still call the PCE-RE 26 or the PCE-RE 15 which collect pressure or levels in addition to wet other physical quantities such as temperature, and can process.
