One is interested in the property, and this inevitably comes the question of moisture, the costly treatments and other measures to follow may have. I had tried to help me with cheap auditors from the hardware store, all of which work with two tips that you have to press in the substance to be measured. This works only partially and by design measures only the resistance or the conductivity on the surface. In addition, the trouble is inevitable when one perforated sensitive surfaces, to just to get a measurement result.
These methods are also inaccurate and provide for. T. catastrophically wrong results.
The unit of Gann contrast - Non-destructive (It does not make holes in the surface, but only specifies the stainless steel ball at) - Measures up to 4 cm in depth
The results are very accurate and, above all, repeatable.
Mich has preserved this device several times before momentous mistakes.
Conclusion: Indispensable when it comes to reliable measuring results on the subject of "building moisture".
