Design / Working
Selected basic material of black natural hardstone finest diabas. The precise-worked faces are finest ground and lapped. The two flat faces are finely worked. With through hole(s) for weight reduction.
Also available as a weight-reduced construction.
Accuracy
JFA precision grade 'I++' or 'LAB'
Calibration certificate
A test certificate is part of scope of delivery. The measuring results are retraceable to National standards. On request and additional costs: Fabrication or DAkkS-Calibration certificate.
