TQC Concrete Moisture Meter


The TQC LI9200 Moisture Meter is ideal for testing moisture content of concrete floors or structures prior to coating application or installation of flooring. This meter is easy to use: simply select the desired moisture scale, and press the electrodes on the base of the meter to fully engage all eight against the concrete surface being tested. Readings are clearly displayed on the gauge face.

Non-destructive moisture meters measure electrical impedance generated between the electrodes while they are in contact with the concrete surface. Depending on the moisture content, measurements are made to a depth of several centimetres.

TQC Concrete Moisture Meters contain four moisture scales to permit moisture measurement of a variety of substances:

  1. Concrete 0-6% H2O

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.
 

2. ~Carbide Method 0-4% H2O

Carbide scale shows concrete humidity according to the carbide method.
 

3. Relative Scale 0-100%

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.
 

4. ~15. Scale 0.3-15.3m

~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.
 

Limits of non-destructive moisture testing of concrete:

The TQC Concrete Moisture Meter does not detect concrete moisture through electricity-conducting materials like metal coverings/ linings, PE-rubber or any wet surfaces.

LI9200 Moisture Meter should not be used to measure concrete moisture on surfaces which are topped with a thick layer of floor covering material like wood.

Meter measurement outcomes show the actual moisture at a time of measurement.
