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 instrument. Depending on the moisture content the measurements are made to a depth of several centimetres. TQC Concrete Moisture meters are ideal to quickly test large concrete floors or constructions which have to be painted or where (wooden) floorings are being installed. Four scales allow flexible use of the instrument as an accurate measuring device or just as a detector to find moisture traces or leakage: Concrete scale may be used only for concrete surfaces. It shows the relation between weight of pure water contained in the tested material with its dry weight. The scale range varies between 0 and 6% as 6% is about maximal physically possible content of water in the concrete. The obtained results should not be confused with moisture emission or any other humidity measurement methods. Carbide scale shows concrete humidity according to the carbide method. Relative scale may be used in humidity level comparison of various materials. Obtained results should not be interpreted as percentage content of water in tested surfaces. There is no linear correlation between the outcomes and relative humidity. The scale should be used only as comparison technique. Scale may be used on the surfaces where direct contact with pure concrete is impossible because of some layer/covering. 15. Scale works in a similar way as the Relative scale and can be used alongside meters with the same scale, which ranges between 0.3 and 15.3.

Never drop it or knock it over • Always clean the instrument after use. • Clean the instrument using a soft dry cloth. Never clean the instrument by any mechanical means such as a wire brush or abrasive paper. This may cause, just like the use of aggressive cleaning agents, permanent damage. • Do not use compressed air to clean the instrument. • Always keep the instrument in its case when not in use.
