shove / skidmatch

Shove/skidmatch is a length measuring instrument which can be used to measure the length of an object with accuracy up to 0.1 mm. profits are sliding-term use can be used to measure the diameter of a marble, the diameter of a tube or ring, or into a tube.


shove consists of two parts, namely fixed jaw and the jaw slide. Shove also consist of two main parts, namely the scale contained in the fixed jaw and scale Nonius (Vernier) contained on the sliding jaw.



Shove accuracy is half of the smallest scale. So shove accuracy are: Dx = ½ x 0.01 cm = 0.005 cm

Ten major scale has a length of 1 cm, in other words the distance of two adjacent main scale is 0.1 cm. Whereas ten Nonius scale length 0.9 cm, in other words the distance of two adjacent Nonius scale is 0.09 cm. So different from one major scale with a Nonius scale is 0.1 cm - 0.09 cm = 0.01 cm or 0.1 mm. So that the smallest scale of the shove is 0.1 mm or 0.01 cm.

With the accuracy of 0.005 cm, the slide term can be used to measure the diameter of a marble or a ring with a more rigorous
