Υγρασιομετρο Tramex CME4
Description Tramex CME4
The Tramex CME4 detects and evaluates the moisture conditions within the cementitious slab or screed by non-destructively measuring the electrical impedance, which varies in proportion to the moisture content in the material under test. The electrical impedance is measured by creating a low frequency alternating electric field between the parallel co-planner electrodes as illustrated in the diagram below.This field penetrates the material under test. A very small alternating current flows through the field. The Tramex CME4 detects this current, determines its amplitude and converts it to a moisture content value. By simply pressing the CME4 down on the surface in strategically chosen locations, instant readings can be taken over a large area.
