Calipers

Description

Calipers are measuring tools used to determine the distance between two opposite sides of an object. They come in various forms, each suited for different applications and levels of precision. Here’s a breakdown of the main types of calipers:

• Based on Measurement Principle
  • Vernier Calipers
    These are the most common type and use a sliding jaw that moves along a main scale. A vernier scale on the sliding jaw allows for more precise readings than a simple ruler. They offer good accuracy and are widely used in machining, engineering, and DIY projects.
  • Digital Calipers
    These are the most modern and user-friendly type. They have an electronic display that shows the measurement digitally, eliminating the need to interpret scales. They are highly accurate and easy to read.
  • Outside Calipers
    • Purpose
      Used to measure the outside diameter or thickness of an object.
    • Design
      Have two external jaws that expand outwards.

  • Inside Calipers
    • Purpose
      Used to measure the inside diameter or width of a hole, slot, or recess.
