Concrete Moisture Meter

TQC-Sheen Concrete Moisture Meter is a non-destructive moisture measurement device. Operating by measuring electrical impedance, this device easily determines the moisture content inside concrete by simply placing the device on the concrete surface.

The electrical impedance is measured by generating a low-frequency electric field between 8 electrodes located on the device’s base. Depending on the moisture level, measurements are taken from several centimeters below the surface.

This system is not suitable for measurements on conductive surfaces such as metal, rubber pads, or wet floors.

TQC-Sheen Concrete Moisture Meters are ideal for quick testing of concrete floors and structures that require painting or wooden flooring installation.

The device offers eight different scales, allowing use either as a precise measurement tool or as a detector for moisture traces and leaks.

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 the maximum physically possible content of water in the concrete. The obtained results should not be confused with moisture emission or any other moisture measurement methods.

2) Cement screed 0 – 6% H2O
This scale is used to measure the moisture content of cement screed. The content of water is expressed as a percentage of weight.

3) Cement Screed 0 – 4% Carbide Method
This scale is used to measure the moisture content of cement screed. The displayed value is an approximate value that can be also determined using the Carbide Method (CM).

4) Anhydrite Screed 0 – 3.5% H2O
This scale is meant for moisture measurements in anhydrite screed. The content of water is expressed as a percentage of weight.

5) Anhydrite Screed 0 – 1.9% Carbide Method
This scale is meant for moisture measurements in anhydrite screed. The displayed value is an approximate value that can be also determined using the Carbide Method (CM).

6) Caisson 0.3 – 15.3 m scale
Caisson scale works in a similar way as the Relative scale below and can be used alongside meters with the same scale.

7) Relative Scale 0 – 100%
Relative scale may be used in moisture 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 moisture. The scale should be used only as comparison technique and may be used on the surfaces where direct contact with pure concrete is impossible because of some layer/covering.

8) Gypsum 0 – 10%
This scale is meant for moisture measurements in gypsum.

Features such as “max-hold” enable ease of use in hard-to-reach places, and an automatic shut-off function is included.
