Test Straight-Edge Q3

The test straight-edge Q3 has two flat and parallel measuring surfaces. The two measuring surfaces are lapped very finely in highest accuracy. The accuracies are, depending on the customer demand, between DIN 876/00 (4 µm at L 1000 mm) and DIN 876/0000 (1.0 µm at L 1000 mm). From dimension 1000 upwards there are handholds on both sides.
