Impulse Hammer and Impact Systems for reliable and Early Detection of internal Defects in Wood

The Electronic Hammer is the ideal measurement instrument for the non-destructive evaluation of internal defects in trees. The Electronic Hammer measures the time it takes an impulse to travel through a tree, i.e. between an impact screw and a sensor screw. Due to the characteristic’s speed of sound for each tree specie, the measured values clearly display the inner conditions of the tree.

Measuring Method
The Impulse Hammer measures the time it takes sound to travel through a tree or timber structure. An impact screw, which sends the sound into the wood, is installed into the tree.
A sensor screw, installed on the opposite side, measures the time it takes for the impulse wave to travel from the impact hammer to the receiver. Because wood characteristics differ, travel time varies between tree species. The Electronic Unit of the Impulse Hammer measures and saves the data, which then can be downloaded to the IML Software I-Tools Light for further analysis.

Use your data effectively
With the IML Software I-Tools Light, data can be downloaded into the computer for further analysis. There the data can be stored for years and referenced as needed.

The IML Software runs on Windows™ 95/98/2000/NT 4.0, XP and Windows™ VISTA.

The Integrated Impact System
The integrated impact system is mostly used for measurements of playground equipment or timber poles, as well as for evaluations of timber structures (inspection of half-timbered houses and construction wood). It is important that the point of the impact screw penetrates the bark easily, so that the impulse can be introduced directly into the sapwood. The adapters for the impact system can remain on the hammer but while working with the wood screws; the handle must be removed.

The Integrated Impact System in Trees
When inspecting trees it is very important that the point of the impact screw is in the sap wood and not only in the bark. Otherwise the measurement will be wrong! Screws are used for measurements of trees having a thick bark.
