Insulating all however the ideas of these pins prevents a false moisture content reading and supplies a extra correct reading on the depth the place the information of the pins are uncovered. Yes, it's possible to have a moisture content material studying of ninety nine.9%. It can be attainable to have moisture content material readings over a hundred%.
