Safety with our system
A good analysis gives the correct answer

Drilling Resistance Measurement
Approved procedure, quick results

The IML Resistograph System is based on the principle of measuring the drilling resistance. A drilling needle is inserted in the wood under constant drive. While drilling, the needed energy is measured depending on the drilling depth of the needle.
