Parallax-Free Vernier Caliper

The PFVC vernier caliper reads to 0.02 mm and 0.001 inch on dual metric and imperial scales, in 0-150, 0-200, 0-250 and 0-300 mm ranges. Before digital readouts, precision came down to the scale itself. This one is fully analog, machined from solid stainless steel — no battery, no display, nothing to fail. Parallax-free graduations line your eye up square with the beam and remove the commonest source of manual reading error, which is parallax. That 0.02 figure is the least count: what you actually read. The mono-block frame takes out the flex points that make readings wander, and it is a four-way caliper — outside, inside, depth and step in one tool.
