measurement instrument
Quick Summary
A radius gauge is a measuring instrument used to determine the curvature of internal and external fillets. It is a type of form gauge, which checks the profile of objects. Radius gauges consist of packs of blades, each with a concave or convex circular profile. These blades are used to measure the radii of grooves and corners. Gauges, in general, are devices used in manufacturing and engineering to check if a dimension is within a specified tolerance range compared to a reference standard.12
