What Is A Caliper?
A caliper is a tool used to measure the distance between two sides of an object: you can measure, with an accuracy down to 0.01mm, a size which otherwise would not be easily measurable with any other tool. Nowadays, digital calipers have become much more popular, due to being far more easier and more accurate.
What Is A Vernier Caliper?
These are similar to a slide rule: they are completely stick shift, so they are perfect for those who don’t get confused easily when it comes to reading numbers and measures. They have no dial or display, so reading must be calculated directly on the body (by lined increments). Due to misinterpretation, they are hard to read. Still, they are sturdy and shock resistant, in addition to being less expensive than dial and digital models.
What Is A Dial Caliper?
This kind of caliper is relatively easy to use. They have a lined dial that shows the measurement, so all you have to do is add the slide measurement to have the exact and final measurement. Their cost is a little bit higher and they are less shock resistant compared to verniers.
What Is A Digital Caliper?
These are the ultimate tools for those who definitely aren’t math people, but also for taking highly precise measurements. They accurately display up to 0.025mm (0.001”) and can take absolute and incremental measurements. Obviously, digital calipers are more likely to be damaged from a shock; moreover, they may lose accuracy if you work in contact with oil or dust and they are more expensive than other types. Always remember to keep batteries with you, so you don’t risk finding yourself with a dead caliper while you work.
