The blue series from Gann are hand-held measuring devices for continuous professional use. These moisture and temperature measuring devices are indispensable instruments in various industries. They are used to determine the dew point and temperature, as well as the moisture content in materials such as concrete, screed and wood. In construction, moisture measurement in walls is essential in order to check the building fabric for moisture damage or mould growth. Before laying floor coverings in particular, it is important to check that the screed is ready for covering in order to prevent subsequent damage and warping of the material. Brands such as Gann offer specialised devices for this purpose, which support quality assurance through precise measurements. Moisture measurement also plays a central role in the restoration of buildings in order to ensure the preservation of historical substances. Moisture analysers are therefore indispensable tools for both commercial and private users who value an intact and dry building fabric.
