Looking for a new digital calipers? Look no further! We put together the 5 best digital calipers for engineers, spanning all price points. Hope we can guide you on your way to measuring more accurately!

What Is A Digital Caliper?

Digital calipers are instruments used for measuring and are typically used in manufacturing settings (among others) to give an accurate measurement of a certain object. They consist of a set of jaws at the end of a long beam that has a scale marked along its edge, this is used to take outside, inside, and step measurements. It also features a depth probe that slides along the beam, this is generally used for measuring depth.

How Does It Work?

The two jaws are moved apart and towards each other with gearless precision in order to take the measurement of the object between the jaws. One jaw moves up and down the beam while the other is fixed to the end of the scale. With digital calipers, the reading between the jaws is generated electronically and shown on a high-resolution, digital screen. As opposed to this, measurements must be taken manually with Vernier calipers. Digital calipers can also tke differential measurements, as they can zero their display at any place on the scale.

While there are many other factors that determine the quality and features of the various digital calipers out there, lets dive into each model and differentiate between them there. Then we can explain the actual differences instead of discussing them in theory!
