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 - 600 mm
Block pitch accuracy: +/-7.0 um for 20 - 300 mm; +/-4.0 um for 350 - 600 mm
Parallelism of blocks: 2.0 um for 20 - 300 mm; 4.0 um for 350 - 600 mm
Mass: 8.5 kg

Dimensions:
Metric 600 mm model.
