Approved procedure, Quick results
The IML Resistograph System is based on the principle of measuring the drilling resistance. A drilling needle is inserted into the wood under constant drive. While drilling, the needed energy is measured depending on the drilling depth of the needle.
That way, anywhere and with little effort it is possible to get information about structures, inner defects or residual walls of trees and wooden constructions. Depending on the instrument series, the obtained data can be recorded electronically and then transmitted, evaluated and processed on your PC with specific software. This is a precision instrument that delivers significant results.
The result:
Depending on which instrument you use, the measurement data is printed simultaneously on a (wax) paper strip on a scale of
1:1. The measurement profile delivers information about the internal condition of the wood. It shows annual rings and density behavior, as well as decayed zones in the wood.
