The image shows a close-up of a mechanical instrument, specifically a caliper, being used to measure the thickness of a piece of metal. The caliper has a black handle and a silver body with numbers and markings on it. The body of the caliper is made of metal and appears to be made of steel. There is a small hole in the center of the body, which is likely where the metal is being measured. The metal is resting on a gray surface, possibly a table or countertop.
