What is a hygrostat?

The hygrostat is used to control and monitor the relative humidity and/or temperature of a room and to control downstream humidification/dehumidification equipment or cooling/heating systems. The task of these sensors is to reliably and constantly maintain the defined setpoints for temperature and humidity of the place of use.
A hygrostat is typically placed in ventilation ducts, air-conditioning ducts, production rooms, climate control cabinets, greenhouses or swimming pools - in other words, wherever humidity needs to be controlled or monitored, our hygrostats are in use.
 

What is the difference between a hygrostat and a hygrometer?

The terms hygrostat and hygrometer often appear together. Both devices are related to measuring the humidity of a room. However, while a hygrometer is purely a measuring device that determines the relative humidity of the room air, a hygrostat is a more complex device.
Like the hygrometer, the hygrostat also measures and controls the relative humidity in a room. Afterwards, however, the hygrostat switches the connected humidifier or dehumidifier or heating system to keep the level of humidity in the room within the specified target range.
 

How reliably does a hygrostat work?

Our surface-mounted and duct hygrostats for controlling humidity and temperature are IP65-compliant. Room hygrostats achieve protection class IP30. All sensors comply with the EN 60730 standard and have a measuring accuracy of ± 2.0 % r.h. This makes our hygrostats extremely reliable and versatile.
