A micrometer (with its own stand) specifically designed to measure the thickness of gaskets used in diamond anvil experiments. The micrometer has a resolution of 0.00005 in./0.001 mm and digital display.

The tips of the micrometer have a conical shape ending a round end which is shaped as a half sphere.

The conical tips have a 15°  angle, finishing with a diameter of 0.6 mm. The half sphere has a radius of around 0.3 mm.

This make this device suitable to measure gasket indentation down to 0.2 – 0.3 mm in diameter depending on the depth of indentation.
