The humidity detector is a small and reliable measuring instrument for the determination of existing moisture in, for example, concrete and wood. Corresponding scales for measuring moisture are already stored in the library of the moisture meter. After selecting the scale, the required measurement can be carried out with the humidity detector. The measurement result is displayed on the humidity detector both numerically and graphically after a few seconds. 

For each scale in the humidity detector, a separate alarm limit can be stored. As soon as the set alarm limit is exceeded, the humidity detector will sound an audible alarm. In order to save the inserted batteries with the humidity detector, the meter shuts itself off after 5 minutes if not used. 

Another special feature of the humidity detector is the possibility of displaying the calcium carbide method (CM%) for screed. Also in this measurement, the humidity detector is placed on the surface to be tested. Based on the corresponding scale, the measured value is converted into a CM% value (calcium carbide method). This gives the operator a guideline value via the calcium carbide method.
