Digital calipers are used to measure the distance between two distinct points. They can also measure internal and external distances along with depth.  If you are in one of the trades listed above, having a good quality digital caliper can save you a lot of work.

What Makes a Good Digital Caliper?

It doesn’t matter what profession you are in, if you have ever used tapes and rulers to try and get an accurate measurement, you know the frustration that they can produce.  This is the reason that digital calipers are so popular.  They take away the guesswork and headache of getting those accurate measurements in a simple, fast, and efficient way.

They are designed to be accurate on a regular basis.  They are used in many different situations including measuring the depth of various holes. They can even be used to measure body fat.  It may be overwhelming to sort through the large selection of calipers that are available, but we’re here to help.

Digital caliperWhen you are looking for a high quality digital caliper, you want the quality of the construction to the type of readout they have to be top of the line. This will ensure even more accuracy.  There are three different types of calipers:

  • Vernier
  • Digital
  • Dial

This review will discuss the features that you should look for in a digital caliper to ensure you have the best one you can get.  Digital calipers are made to be easy to read, and the best ones require no squinting at tiny little lines trying to get a precise reading. They also don’t require any adding.

On a digital caliper, the readings will be displayed on an LCD screen so you will know the exact reading.  On dial and Vernier calipers, you will sometimes need to estimate.  Some of the drawbacks that people have identified in using digital calipers are the fact that you will need a battery to operate them and also that they tend to be the more expensive option.

You will also want to look for a digital caliper that is constructed from durable stainless steel and that will measure interior, exterior, depth, and step dimensions.  Make sure that the model you choose offers both metric and standard readings.

Battery life is another factor in choosing a superior digital caliper.  You don’t want to have to worry about your battery running low all the time so look for high quality batteries that will last a good, long time.  Extra large displays, push button switch that allows you to go from metric to standard, and depth gauge and accuracy to .02 mm are the most important features to look for.

Parts of a Digital Caliper and Their Uses

  • Depth Gauge – T-his measures the thickness of objects and also the depth of a hole
  • Locking screw – This feature will prevent the jaws of the caliper from moving while you are measuring
  • ABS button – This will temporarily set the current measurement to zero
  • Step gauge – This gauge measures the distance from one edge to another point on the object
  • Outside Jaws –  This part of the caliper measures the outside dimensions of an object
  • Inside jaws –  This part measures the inside dimensions and are very delicate and breakable so care must be taken not to break them
  • On/zero button – this will set the current position to zero and turns the calipers on as well
  • In/mm button – this convenient feature switches the measurement from inches to mm
  • Battery compartment – holds the battery that operates the caliper
