Vernier Caliper v66.5.14 MOD APK (Remove ads)

Precision Measurement Simulator is an interactive virtual metrology laboratory for learning how to read and use vernier calipers, micrometers, dial indicators, comparators, gauge blocks and angle-measurement instruments.

Practice precision measurement with realistic virtual tools inspired by instruments used in mechanical engineering, machining, CNC training, manufacturing, dimensional inspection, quality control and technical education. Manipulate the instruments, read the scales, enter your answer and receive instant feedback.
