Hygrometer & moisture meter | The importance of a hygrometer

Hygrometers and moisture meters

High humidity and mositure creates very good growth conditions for mould. In addition, house dust mites thrive in a humid environment.

If you have a humid indoor climate, it would be a good idea to have the moisture percentage in floors, walls and ceilings checked. Moisture in the air has a tendency to settle on cold floors and walls in particular.

A moisture meter can help improve your indoor climate

If you have been exposed to water damage, you should have the moisture percentage in floors, walls and/or ceilings examined, depending on where and how extensive the water damage has been. You can measure the moisture percentage in materials with a moisture meter.

If the moisture in materials exceeds 15-18%, the material is so moist that it creates ideal growth conditions for mould. You should therefore ensure that the material is dried and, just to be on the safe side, have mould remediation carried out in the areas that have been damp.

Moisture in the indoor climate (air) is referred to as relative humidity and can be measured with a hygrometer. If the relative humidity exceeds 75%, mould can germinate and grow.

Use a moisture meter before renovating

If you are going to paint a wall, for example, it would be a really good idea to use a moisture meter to check whether the area is dry. If you paint on a damp area, such as woodwork, you risk trapping moisture in, which can lead to problems with both rot and fungus.

The moisture content of the materials you are going to paint on should therefore not exceed 15-18%. If it is damper than that, you should first dry out the area and possibly remove any mould before you start painting. We also recommend that you always use permeable (breathable) paint.

If you have a wood-burning stove, a moisture meter is also a good tool to have on hand. This way you can quickly check whether the wood is dry enough to use for heating. It should not be damper than 20%.

Damp wood does not give off as much heat as dry wood. Furthermore, damp wood can both pollute and soot the chimney.

A typical sign of an excessively humid indoor climate is condensation on the windows

Inadequate ventilation increases humidity

Since we humans release around two liters of moisture every day through breathing and the skin, we can quickly develop problems with humidity. With no or inadequate ventilation, the humid air can create a poor indoor climate.

A typical sign of an excessively humid indoor climate is condensation on the windows. However, you can get the best indication by measuring the humidity with a hygrometer.

With us you have the opportunity to buy or rent professional humidity meters that can measure both relative humidity and the humidity in materials. We also offer various hygrometers that can measure the relative humidity.
