RS PRO Caliper 300 mm 0.02 mm Resolution Vernier, Metric, Imperial

RS PRO Fine Adjustment (6in. and 12in.)

RS PRO fine adjustment Vernier Calipers feature dual scales with both metric and imperial readings of internal and external precision measurements. The adjustable mechanism has two lockscrews so you can accurately measure objects with ease. The calipers sliding surfaces are raised to prevent wear to the scale. Internal jaws, external jaws and a sliding depth rod provide four ways to measure.

Two graduated scales:

The main scale which is similar to that on a rule plus a specially graduated sliding scale (called the Vernier scale).

The Vernier scale slides parallel to the main scale and enables precise readings to be made to a fraction of a division on the main scale.
