!nstrumenTool

magnetic caliper

A new digital thickness gauge for measuring violin family instruments, guitars and for wood bowl turning. It can measure the thickness of nearly any material (except steel) between 1mm and 10mm thick to the nearest 0.1mm. A luthier's and woodturner's helper, !nstrumenTool is also handy in many other situations where traditional calipers are difficult or slow to use.

And...it should work fine on nearly any non-ferromagnetic material (ie. nearly anything except steel). So you could measure the thickness of a piece of glass, plastic, ceramic, wood, aluminium or copper as long as the two surfaces of the material are near parallel and it is not thicker than the maximum tolerated by the !nstrumenTool. It also helps if the material can be positioned so that the !nstrumenTool magnetic caliper is being used either
