The KC-318 Non-Invasive Inductive Moisture Metre is a versatile device that provides moisture readings for four different wall and material types; dry wall, masonry, softwood and hardwood. It uses a sensor at the back of the tool to emits and receive electromagnetic signals through the material to be tested to determine its moisture content.
The reading displayed is an average value of the moisture content from the entire surface area and the maximum depth of penetration. Moisture which is closer to the surface has a greater effect on the average value than the moisture close to the maximum depth of penetration. KC-318 includes an internal auto-calibration function so there is no need for manual calibration
