A moisture meter is an instrument for measuring moisture content in building materials such as in crawl spaces and attics. You can also use it to check if firewood is adequately dry for burning. It is a practical device for measuring the moisture content of wood before painting, building and installing floors to prevent cracking, twisting and warping. Moisture meters can be used to measure the moisture content in several different materials such as sawn wood, concrete, mortar, plasterboard and cardboard. By measuring the moisture content in your house you can find out if there is damp in the bathroom, attic or basement for instance. Then you can take action to minimise the risk of mould damage and get the space dry. A moisture measure is great for using when renovating old houses or buildings to see if you need to replace any of the materials in the walls or floors. A damp free home is better for your health.
