• High quality, special alloyed and tension-free special steel, very stable and adhesive. Heat treated and finely lapped. Slightly broken edges.
• Each size scale has a serial number on it. The size scales have a Rockwell 800 HV (64 HRC) hardness and are very stable and resistant to wear.
• The length scales are placed in a wooden box immediately after being calibrated. The wooden box is included in the price.
All size scales are delivered with a calibration certificate with traceability documented according to international norms.
In addition, size scale sets with calibration class K are measured interferometrically by the NKO authorized laboratory.
