TWC II BT

One hand operated electronic diameter caliper with three wheels for measuring large trees

TWC II BT

TWC II BT 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, and diameters larger than 360 mm by three point arc measurement. When all three rollers touch the tree, caliper calculates a diameter of the circle passing these three points.
