Description Of Device; General Function - WOLFF VI-D4 Traduction Du Mode D'emploi Original

1.

Description of device:

VI-D4 meter was designed in order to measure concrete humidity. Its unquestionable advantage is
nondestructive method of measurement with simultaneous high accuracy and easiness of use.

1.2.

General function:

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.
1.3. 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.
