The Sylvatest 4, a revolutionary tool for wood sorting - The fourth generation of this cutting-edge technology, the Sylvatest 4, also known as Quattro, allows for the evaluation of the mechanical properties of wood through longitudinal, direct, or indirect measurements. This technology applies to both squared wood (such as sawn timber and glued wood) and round wood (such as logs). For common species, the results obtained allow for the determination of the mechanical strength class of the wood according to current standards (SN in Switzerland, EN 338 for Europe).
