Description
Glastonbury?s Vernier Masters are used to calibrate and adjust calipers. The master is superior to gage block calibration because it does not require gage block stacks and therefore it is much faster to the inspect linear range of the tool. In addition they indicate wear on the caliper anvils because both the ID and OD jaws are inspected without additional setup.
