What is a vernier calipher? Who uses them in their workplace?

Answer 1

It looks like a slim monkey wrench with the jaws bracketing the part whose diameter or thickness it measures.

The vernier scale cleverly amplifiers the millimeter (or 1/16 in) marks by fractional offseting them so that from 1/10 to 1/50 of a millimeter can be detected by the naked eyes. On the stationary side, millimeter marks of true spacing are impressed. On the sliding side "millimeter" marks that are 10% wider than true spacing are impressed. As the two offset scales are repeated over several centimeters (or inches), the perspective symmetry of the misalignment aids the eyes in detecting which fractional-offset pair of marks best align from across the two sides, enabling the differentiation among very fine misalignments. Sorry, but you have to use it to really appreciate the elegant simplicity.

Machinists, mostly manual lathes, use it the most.

Answer 2

Actually it is "Vernier Calliper", it is a device used for measuring diameter of small spherical/cylindrical bodies. This instrument is used to measure accurately up to (1/10)th of a millimeter. It includes:-
1. Main Scale: A scale for measuring in millimeters and centimeters.
2. Vernier Scale: It is a sliding scale. The side or Vernier scale lying towards the mm side of the main scale has 10 equal parts (divisions) and the 10 div. of Vernier scale coincides with 9 div. of main scale.
3. Jaws: It has jaws. Upper jaws are used to measure internal diameter and lower jaws are used to measure length, external diameter, etc.
4. Strip: It is used to measure depths of hollow objects (cylinder, beaker, etc.)
For better understanding you need to see it how it looks and works. This device is generally used in labs of school and in engineering colleges.

Answer 3

Vernier calipers are hardly ever used today. Others have explained how a vernier scale allows you to read precise measurements. The dial caliper with a simple readout dial replaced the vernier about 10 years ago. Mopre recently digital calipers with an electronic digital readout have largely replaced dial calipers. I do not believe vernier calipers are made anymore. They were a brilliant way to get precision but modern manufacturing techniques and electronics have made them obsolete.

Answer 4

A vernier caliper is used to measure very precise distances Like the length of a piece of metal or the thickness of a pipe.

Machinists use them extensively to make precise measurements metal and other machine parts they are making.

Answer 5

vernier caliper is a hand held instrument used to measure length, diametre, depth of small objects.
u can find it in physics lab
mechanics use it
machinisits use it
hardware stores use it
engineers use it

Answer 6

it is used to measure the thickness in minute detail usually scientists use it for exact measuring carpenters use it in their work place
