How do you use Vernier caliper for an accurate measurement of distance?
Absolutely, there is no other device than a Vernier Caliper which provides exact measures, especially for linear dimensions. If you want to measure the diameter of a round object like a ball or a cylinder, bring Vernier Caliper into use to get the best results. What makes it so effective and widely popular? Because the measuring jaws can be secured on either side of the circumference, thus provide exact measures.
How Does a Vernier Caliper Work?
Vernier Calipers give a direct reading of the distance measured with high accuracy and precision. Being functionally alike, they come with the ability to read the results using different ways.
Vernier calipers comprise a fixed main scale as well as a moving Vernier scale, with a pointer, that slides along the scale. The main scale is graduated in either millimeters or tenths of an inch. The credit of the precise readings that the user gets should actually go to the Vernier scale.
It usually gives a perfect reading to the nearest 0.02mm or 0.001 inches. Therefore, in comparison with a standard ruler, which only gives reading to the nearest 1 mm or 0.25 inch, Vernier scale proves to be highly accurate.
History of Vernier Calipers
This extremely useful measuring instrument was first sited in the Greek Giglio wreck close to the Italian coast. The ship was wrecked in the 6th century BC. Its wooden piece had a fixed and a moveable jaw. Although being so rare, Greeks and Romans kept on using calipers. As time passes, a bronze caliper was found in the 9 AD and was used for subtle measurements during the Chinese Xin rule.
The modern Vernier caliper, which can read thousands of an inch, was invented by an American inventor named Joseph R. Brown in 1851. A very interesting fact is linked with this device is that it was the first practical tool for precise measurements that was sold at an affordable cost for ordinary machinists.
