The GMK 100 & 210 are nondestructive moisture measuring devices that use the capacitive measuring method. Depending on the application, it is possible to display the material moisture “u” or the water content “w”. The humidity is measured by a measuring plate on the back of the device. With a side-mounted switch the measuring depths can be changed. The GMK 100 is suited for building materials as it can measure the moisture content of wood, concrete, plaster and other materials. The GMK 210 is especially designed to meet the needs of moisture ratings of boats, camper vans and caravans as it can measure wood and fiberglass. Product code: GRE-GMK 100 & 210
