The damp meter consists of an infrared thermometer and an integrated humidity meter. With the two sensors, it can record values to determine the dew point. If this dew point is reached or undershot, there is a risk of moisture settling and mold growing. The dew point, which is calculated by the damp meter, is displayed on the high-contrast LCD display. The control buttons can be used to set alarm values. If the surface temperatures are exceeded or undercut, the damp meter emits a warning tone and displays either a LOW or a HIGH alarm. 

The damp meter also has a relative value measuring function. Thus, in the structural analysis, a temperature can be stored as a reference in the instrument by a measuring point. If further measurements are subsequently carried out, a good / bad evaluation by the damp meter is carried out via a colored bar graph. Furthermore, the damp meter offers the possibility to determine the maximum, minimum and average value of the infrared temperature.
