Dial Vernier Calipers

Dial Calipers is an advanced version of vernier calipers. In dial calipers vernier scale is replaced with a dial with a needle rotating in 360 degrees as you move the movable jaw of the dial caliper. The motion of the dial needle is achieved accurately by using precisely manufactured rack and pinion mechanism. The dial caliper eliminated the difficulty in reading the vernier scale especially one with small least count. Dial caliper also eliminated the parallax error which can occur from reading a normal vernier calipers with vernier scale.
