General description:
VI-D4 meter calculates humidity of analyzed material by measuring its electrical impedance. The relation
between humidity of certain material and its impedance is directly proportional. Impedance is measured through
generating low frequency electric field between electrodes. The meter measures low intensity alternating current
flowing through electric field and on that basis calculates moisture of tested material.
Constraints:
Concrete Moisture Meter VI-D4 does not detect concrete humidity through electricity conducting materials like
metal coverings/ linings, PE-rubber or any wet surfaces.
Moisture Meter VI-D4 should not be used to measure concrete humidity on surfaces which are topped with a
thick layer of floor covering material like wood.
Meter measurement outcomes show the actual humidity at a time of measurement.
