Humidistats: How They Impact Facilities Management

Humidistats are electronic devices used to regulate humidity levels in a particular environment. They are used in a variety of settings, such as commercial and industrial buildings, residential homes, and greenhouses. For facilities managers, humidistats are an essential tool for maintaining comfortable and safe indoor air quality.

What is a Humidistat?

A humidistat is an electronic device that measures and controls the humidity in a given area. It works by sensing the relative humidity of the air and then activating a device, such as a fan, to adjust the humidity. This helps to maintain a comfortable level of humidity which is essential for healthy indoor air quality.

Why Do Facilities Managers Need Humidistats?

Humidity levels are important for a number of reasons. High humidity levels can cause mold and mildew growth, which can be dangerous for occupants of a building. Too much humidity can also damage furniture, electronics, and other items. On the other hand, too little humidity can make a space feel dry, uncomfortable, and lead to other issues such as static electricity.

For these reasons, facilities managers need a way to accurately measure and control the humidity levels in their buildings. Humidistats allow them to do this easily and efficiently. By monitoring and controlling the humidity levels, facilities managers can ensure a safe and comfortable environment for occupants and protect their investments.
