What is air gaging? The what, who, why, and where of air gaging.

The measurement of the depth of a hole sounds straightforward and simple. In many cases it is. In others, there are design features of both the part and the gage that must be considered to insure an accurate measurement and a properly assembled or functioning part. 

The Multimar 844 T Universal Measurement Gage from Mahr Federal takes your large ID and OD gaging to the next level. Built on a finely ground, hard chrome-plated column, and available in a range of sizes, the Multimar 844 T can measure ODs and IDs up to 2500 mm with extreme sensitivity and accuracy. New Multimar 844 T gages now include a number of improved features that make them more precise, more stable, and more flexible than ever.

For small to large parts, shallow grooves are always difficult to measure.
