A vacuum gauge is an instrument used to measure pressure below atmospheric pressure (i.e. pressures less than ambient). In other words, it quantifies how “empty” a space is, or how many molecules remain in a chamber compared to normal atmospheric pressure.

A radius gauge, also known as a fillet gauge, is a tool used to measure the radius of an object. Radius gauges require a bright light behind the object to be measured. The gauge is placed against the edge to be checked and any light leakage between the blade and edge indicates a mismatch that requires correction.

A   Depth Gauge  is used to measure the depth of holes, slots, counterbores, recesses, and the distance from a surface to some recessed part. This type of micrometer is read exactly opposite to the method used to read an outside micrometer.
