With the Mitutoyo 531-108 vernier caliper, you perform accurate measurements without relying on battery power. The spring-loaded thumb clamp ensures the slider stays firmly in place and only moves when you press it, preventing accidental shifts during reading. Featuring a measuring range of 0 to 200 mm, a clear 0.05 mm vernier graduation, and a dual metric and inch scale, it provides maximum flexibility. With its 50 mm measuring jaws, you easily inspect outside, inside, depth, and step dimensions in any workshop environment.
