What is RV?

A healthy indoor climate is essential for a pleasant working, sports and living environment. It promotes productivity and concentration. In storage areas, too, the indoor climate determines the quality of the products stored there. Temperature and humidity play a major role here.

In this case, humidity refers to the moisture content of the air. This humidity level of a room is referred to as relative humidity (RH).

Simply put, therefore, the RH value is a measure of the amount of water vapour present in the air.

Besides "relative humidity", there is also the term "absolute humidity." The latter term is the easiest to understand because it indicates how many grams of water there are in a cubic metre of air. Nature has determined that air cannot absorb water infinitely. There is a physical maximum for this.

This is clarified by an example:

• Suppose the physical maximum is 30 grams per cubic metre;
• In a room, 15 grams per cubic metre (this is the absolute humidity) hangs at that moment;
• Thus, for this example, the relative humidity is then 50%.

The note to be made here is that the maximum humidity depends on the temperature.

We are happy to help you accurately and reliably measure and monitor the RH value with one of our measuring instruments. View our range of RH meters here.
