Measuring beam - straight edge
Measuring instrument for checking straightness and parallelism both quickly and easily. Particularly suitable for checking and alignment of axis of machine tools and co-ordinate measuring machines.
Construction
Finest diabas - granite. Free of faults. No deflection and high torsional rigidity. From a length of 750 mm onwards, the beams have handles at the front faces.
Also available as a weight-reduced construction.
Accuracy
2-sides precise. The 2 narrow longitudinal faces are flat and parallel within the indicated JFA precision grade finest ground and lapped.
Test certificate / Calibration
A test certificate is part of scope of delivery. Measuring results are retraceable to National standards. On demand, a factory calibration certificate or a DAkkS calibration certificate will included in the delivery.
