To determine moisture content, the meter is firmly pressed onto the clean concrete floor surface. Electrodes at the base of the meters instantly determine impedance measurements. HMA-661 Calibration Check Plate is available separately to monitor the proper performance of both meters.
The meters can also be used for comparative readings on materials such as stone, lightweight concrete, self-leveling gypsum floor compound, ceramic tiles, and other masonry-type materials. They are used to identify potential problems such as condensation, blistering, and deterioration of the floor covering, and more.
