Vernier Caliper Analog 150mm

A Vernier caliper is a precision instrument for highly accurate linear measurements (length, depth, diameter) using a fixed main scale and a sliding Vernier scale, which provides finer increments to read fractions of the smallest main scale mark, reducing error from traditional rulers for applications in engineering, manufacturing, and science. Its parts include fixed and movable jaws, a depth rod, and a screw clamp, with measurements taken by placing an object between jaws and aligning scales to find the precise reading.
