TQC Concrete Moisture Meter Non-destructive digital moisture meter for concrete. By means of measuring the electrical impedance the moisture content of concrete can easily be determined by just pressing the instrument against the concrete surface. The electrical impedance is measured through generating a low frequency electric field between 8 electrodes at the bottom of the gauge. Depending on the moisture content th measurements are made to a depth of several centimeters. 0-6% H2O on concrete.
