Description

The M 20-OF 15 Surface measuring cap pair is used for the resistance-based measurement of wood moisture and building moisture on surfaces without damaging the material to be measured.

In the area of wood moisture it is suitable for, e.g. the measurement of veneers, in the field of building moisture for the measurement of concrete, plaster or screeds before the application of a coating such as epoxy resin.
