LIGNOSTATION™

Preparation and recording

lignostation_5.jpg LIGNOSTATION™ is a compact, high-resolution system for preparing wood surfaces and recording the tree ring parameters and the wood density. LIGNOSTATION™, developed in cooperation with the University of Freiburg, is based on an entirely novel concept.

A precision mill prepares the measuring radii on the wood surface. Then, precise scans are obtained using a high-frequency probe. At the same time, optical scans of the surface can be made and analyzed in comparison with the image. The entire system is computer-controlled and relieves you of a great deal of time-consuming routine tasks. You attach the sample, define the measuring radius on the PC screen, and LIGNOSTATION™ will do the rest, from preparation up to measurement. You can fully concentrate on the scientific evaluation.
