Tilswall Pinless Moisture Meter,Wood Moisture Meters for WallsThe pinless moisture meter uses a dielectric measurement method that eliminates the need to insert electrodes or probes into the material to be measured. The high frequency sensor technology allows the moisture meter to detect moisture content at a depth of 20mm below the surface of the object, can test all kinds of materials without destruction. Non destructive Measurement Non destructive induction hygrometer,which transmits and receives high
