The easily exchangeable steel insertion measuring pins of the BM22 enable a solid connection to the test material and ensure reliable measuring results for the wood moisture measurement of sawn timber and firewood or the material moisture measurement in soft building materials such as gypsum, plaster or screed.

A bar scale and the additional direct moisture value display in absolute percentages simplify reading the measured moisture values. Two different scale ranges for wood and building materials increase the accuracy. Three integrated LEDs offer a simple humidity indication by means of the traffic light principle.
 

For wood moisture measurement a calibration curve is stored in the device, which corresponds to the average of the relevant kinds of wood in Europe based on a wood temperature of 20 °C. Therefore, no further settings are required for a quick indication of the wood moisture content.

Further integrated in the protective cap of the device is a reference adapter for the control of the battery status and functions. The likewise integrated LED torch enables working even at twilight or in storerooms which are not brightly illuminated.
