Dial Indicator Diameter Gages measure both outside and inside diameters by comparing dimensions to gage blocks or an adjustable setting master. Each gage consists of a strong rectangular box beam with a sensitive gaging contact at one end and a reference gaging contact at the other. The 1101 gages allow for measurement beyond the size range of our 1102 models. Each gage adjusts a full 6 or 150mm. The contact carriers are vertically adjustable to handle various work depth. Special contacts are available. This tool has dowel (line) contacts at one end of the gage feet, and a button (point) contact gage at the other end of the feet. These can be reversed as needed and the gaging depth can be set within a range of 2-3/4 or 70mm. This gage should be checked against our 1126 Master for a precise reference standard during production gaging. 1200-1350mm Length Range the feet. These can be reversed as needed and the gaging depth can be set within a range of 2-3/4 or 70mm. This gage should be checked against our 1126 Master for a precise reference standard
