WebResistograph is a mechanical resistance measurement device, developed by Frank Rinn (since 1986 in Heidelberg, Germany ). Driven by a drill motor, a long, thin needle is inserted into a wood log or structural wood beam in order to gain an idea of its density, often to identify areas of substandard structural integrity such as decay.
