What is a Vernier Caliper?

A vernier caliper is a dimension measuring instrument that is used to accurately measure not only the internal and external dimensions of an object but also its depth. The instrument which is equipped with a fixed jaw and a movable jaw that moves along a graduated scale can measure to an accuracy of a hundredth of a millimeter. Owing to, both, its exceptional precision and accuracy, the vernier caliper has found a great many uses in a variety of applications & settings.

List of Sectors Where Vernier Calipers are Used

Enlisted below are the top five sectors that rely extensively on the use of vernier calipers:-

#1)Machine Shop Applications

The machine shop is one of the most extensive users of the vernier caliper. The colossal looking aircraft and ships have surprisingly got the most intricate of components that get them to function the way they ought to. The automobile sector also employs the use of these calipers for a number of reasons—from measuring the diameter of the automobile crankshaft to gauging the height of the spring that the vehicle is set up with.

#2)Medical Applications

The medical industry resorts to the use of a plethora of tools and instruments in order to perform a wide range of diagnostic as well as surgical procedures. It is, thus, paramount to know the exact depths and thicknesses of the instruments that are to perform multifarious procedures on the human body. The slightest mistake on the production end may result in the loss of a precious life.

#3)Research & Laboratory Applications

A vernier caliper is used for a multitude of laboratory-based applications. Take, for instance, the use of a vernier caliper to gauge the expansions and contractions of metals and metallic products as the temperature is raised and lowered respectively. The effect of gravity acting on a minuscule-sized object as it rotates in a pendulum-like motion also requires the knowledge of its dimensions and, thereby, its mass.

#4)Locksmithing Applications

The trade of locksmithing involves the use of intricate patterned keys and locking mechanisms.  It goes without saying that locksmiths have to imperatively resort to the use of vernier calipers in order to make precise and accurate cuts through the metallic lock surfaces so as to be able to turn and un-turn them comfortably.  The use of vernier calipers helps measure thicknesses and diameters with great precision.

#5)Educational Applications

Educational institutions and schools bestow their students with the opportunity to use the vernier calipers hands on. Any physics laboratory in a school is likely to house vernier calipers to help students grasp the basics of using a vernier caliper and get a practical demonstration of what is only otherwise taught theoretically in the classroom.

Final Conclusion About the List of Industries Where Vernier Calipers is Used Worldwide

Owing to the critical nature of the dimension measuring applications vernier calipers are used in, the precision tools must always be purchased from reputed brands to enforce accuracy and rule out the possibility of any erroneous measurements. Brands such as Insize, Yamayo, Mitutoyo, Precise, and Inder are leading manufacturers of these instruments.
