Racal TWC has been developed to fulfill the need of measuring large trees. The measuring principle allows to measure tree diameters smaller than 360 mm by conventional principle used in Racal 500. When the diameter is larger than 360 mm the TWC automatically uses three point arc measurement.
One-hand operation principle allows the user to measure accurately and easily even in dense spruce forest. Reaching the trunk by one hand makes the work easy compared to conventional calipers and leaves the other hand free for other work like marking the tree.
Masser EXL- caliper is a special design for measuring logs which has been spread on a yard. This double slide design makes it possible to measure on an upright position without stressing the operators back.
