Best Digital Calipers - Buyer's Guide

accuracy

One of the biggest advantages of digital calipers is their accuracy and this is the feature that you need to look for first. What you measure must be right every single time you do so. Digital calipers typically come already calibrated professionally. To make sure, you can use an analog caliper to check if the measurements are correct.

reliability

Being able to duplicate the measurements you did every single time is important with digital calipers. This is even more crucial when you are fabricating items on a large scale since you need to make sure that their dimensions are all the same. If the caliper shows different measurements for the same item because of some error, this could result in major losses.

modes

Many digital calipers can measure dimensions in millimeters, centimeters, and inches, which is helpful in conversions or keeping your measurements uniform. Having these options is helpful since it ensures that you can change the units with a touch of a button. No more mental calculations or using a calculator.

ease of use

The digital caliper you get should not be difficult to use. You should be able to change the units of measurement at any time and adjust the caliper itself should be straightforward. This means no getting stuck, no difficulty in opening the mouth, and no issues with making precise measurements.

durability

Digital calipers involve a fair number of electronic parts, even if they are simplistic by nature. With that being the case, they should be able to resist a certain level of wear and tear. Ideally, you should also get calipers that are waterproof so that you can work in areas with water.

Best Digital Calipers - FAQs

What benefits do digital calipers offer over non-digital ones?

For starters, there are the huge screens that provide you with the exact figures of measurement and with decimals, too. This makes it much faster to measure and record the thickness or width of objects instead of spending a few seconds looking at notches to make sure that you got it right. You could also change the modes of digital calipers to measure in the unit you want.

How many modes should digital calipers have?

Your digital caliper that offers multiple modes will typically offer three with different units of measurements from millimeters to inches. You will need this if you are not used to converting units in your head or on paper. This is also helpful when you are trying to maintain uniformity with the measurements that you are taking.

What can I use digital calipers for?

Digital calipers can be used much like regular calipers in that they are used to measure thickness, width, diameter, and distal taper. They are typically employed by architects, engineers, construction workers, home improvement personnel, and so on. There are many craftspeople who use them for making their products, as well.

Are digital calipers safe to use around water?

If they are waterproof, then yes, they are. However, there can be conditions such as whether or not the caliper can be submerged in water or if it can survive being absolutely drenched during a downpour. The waterproof feature can differ in terms of quality, after all, and some digital calipers are more waterproof than others.
