The Elcometer 7000 rangeoffers accurate and easy touse moisture measurement. Invasive pins are pushed firmly into the surface of the substrate being measured and by measuring the electrical resistance between the pin electrodes provide the percentage moisture content (%MC) in the substrate. The Elcometer 7000 range offers accurate and easy to use moisture measurement. Available with pin probes or non-invasive for non-destructive testing, the gauges give average moisture content by comparing the change in impedance between damp and acceptably dry substrates.
