Internal Digimatic Tube Thickness Caliper Gage

The Mitutoyo ABSOLUTE digital internal tube thickness gage provides accurate internal dimension measurements of tube thickness, hole diameters, groove thickness and other hard-to-reach dimensions. Measurements are shown on an easy-to-read LCD display.

Features & Benefits

The highly versatile Mitutoyo ABSOLUTE Digimatic internal tube thickness gage is designed to accurately measure the inside diameters of tubes. This tube thickness gage is ideal for measuring other inside dimensions such as hole diameters, groove depths and thicknesses, and other hard-to-reach dimensions. The spring-loaded lever makes the thickness gage simple to use in tight spaces, and the operational buttons provide quick feature and measurement access.
