Technical Data:
Series: 515
Product type: CERA Caliper Checker
Construction: Permanently wrung high-grade CERA gage blocks in protective metal casing
Application: Checking caliper outside measurement, caliper inside measurement and height gage accuracy
Material benefits: High wear resistance; corrosion proof; anti-magnetic; low thermal conductivity; crack and burr resistant
Accuracy reference: Block-pitch accuracy and block parallelism referenced from lower-end reference plane for outside-caliper / height-gage checks and inside-reference plane for inside-caliper checks

Remark:
When used horizontally, the bottom face and measuring face are not precision perpendicular to each other.
Measuring / checking range: 0 - 300 mm
Block pitch accuracy: +/-5.0 um
Parallelism of blocks: 2.0 um
Mass: 4 kg

Dimensions:
Metric 300 mm model.
Block reference positions shown: 20, 50, 100, 150, 200, 300 mm.
Overall reference length=374.5 mm.
Reference section dimensions include 63 mm; 53 mm; 50 mm; 9 mm.
