Anyone who wants to measure moisture quickly or, above all, non-destructively in materials such as wood or mineral building materials or wants to monitor the drying process will find his reliable partner in the BM40. Simply place the measuring electrodes of the device on the material to be tested. Moisture measurement is absolutely non-destructive via capacitive sensors using the dielectric measuring method, since no electrodes or probes need to be introduced into the material to be measured. For increased accuracy of the readings given directly in% by weight, correction factors are available for the different types of material.
