What Is The Best Digital Caliper?
More Detailed Digital Caliper Reviews
Mitutoyo 500-196-30 Digital ABS AOS Caliper Thumb R. w/o Output Review
Mitutoyo are the first name in digital calipers, and are based in Japan’s industrial heartland of Kawasaki. Considered the makers of some of the best digital calipers around, the ones we tried out sure lived up to their good name!
The stainless-steel construction was as you would expect from these Mitutoyo digital calipers. Precision machining and grinding of all metal parts was incredibly accurate and both sets of jaws came together without any gaps or movement at all. The fine adjustment wheel was well knurled and could be locked easily to keep a measurement.
Because they use an electromagnetic ABS encoder, the Mitutoyo 500-196-30 Digital caliper isn’t thrown off by the presence of dirt during measurement. The signal on the electronic caliper is not affected by oil, water or other substances when in use. This really makes a difference when taking vernier caliper accuracy seriously.
The included hard case was of top quality, and the battery life of 180,000 hours is backed up with spare batteries inside. Included with all genuine Mitutoyo products are calibration certificates signed by the manufacturer.
Moore and Wright MW110-15DBL 150mm (6″) Digitronic Digital Caliper Basic Line 110-DBL Series Review
Moore & Wright are part of the Bowers Group, specialists in accurate measurement tools, and have been producing micrometers and measuring calipers for more than a century. The 110-DBL Series micrometer we got our hands on is a well-made and robust instrument that offers full functionality on a budget.
All the measuring parts are made of hardened stainless steel that have been hand finished, so there are no sharp edges or shoddy machining to throw off your measurements.
Included in the four measuring functions are metric to imperial conversion, ABS pre-set function to zero the measurement anywhere on the scale, and an auto off feature after several minutes.
The included case is fit for purpose, and we liked the fact that the one we tried out was supplied with five spare batteries. One of the criticisms of less expensive micrometers is their battery life, so we we’re pleased that Moore & Wright have thought of this issue.
DML 150mm 6 Inch Digital Vernier Caliper Review
Another Sheffield-based UK specialist in handheld metrology, Digital Micrometers Ltd produce a wide range of precision instruments for industrial, automotive, electrical and DIY applications.
The internal and external measurement jaws on this digital vernier caliper are well machined and close together accurately, and the depth gauge is small enough to get into really tight spaces. We’re looking for the best Vernier caliper, so the DML Digital Vernier Caliper is more than suited for the task.
Two other features we like are the big screen that makes looking at the readouts easy in most lights, and the built in reference point that stores the last position when powered off.
Louisware 150mm Electronic Digital Vernier Caliper with Extra-Large LCD Screen Review
The Louisware Electronic Digital Vernier Caliper measures length, inside diameter, depth and step and do so as accurately as a micrometer that costs several times as much.
We put these measuring calipers through their paces and found the hardware to be well machined and finished. They might not have the refined qualities as a much more expensive model, but for hobbyists, DIYers and even professionals, they do the job well.
The calipers are IP54 resistant and, like much more expensive models, feature ABS. For the price, these have to be the best digital measuring calipers available right now.
Adoric Electronic Micrometer Digital Caliper Review
If you are searching for a no-nonsense pair of digital calipers then you cannot go wrong with the popular Adoric Electronic Micrometer Digital Caliper. The Adoric company are well-known for providing useful home gadgets at competitive prices.
This particular instrument has all the basic functionality that its more expensive competitors feature, including the 4 basic measuring modes (inside and outside diameter, depth and step), metric to imperial conversion and zero calibration.
The unit turns on automatically when the jaw is adjusted and turns off after a 5 minute period of inactivity. The large LCD display is also easy to read.
For the price this is a very handy measuring tool for occasional, DIY or home use.
Digital Caliper Buyer’s Guide
When we came to tackle the best digital calipers review, we knew there were several premium brands that would offer excellent quality instruments, but we’ve since been surprised by the quality offered at both ends of the price spectrum. If you need to take accurate measurements, you need the best digital caliper gauge that you can afford, nothing else.
The best digital caliper needs to take at least four different particular measurements accurately.
Inside length is calculated with one set of jaws facing outwards, to measure the inside diameter of an object
Outside length is calculated with another set of jaws facing inwards, to measure the outside diameter of an object
Depth is calculated with a probe that extends from the end of the best digital caliper gauges, to measure recesses, gaps and hard to reach areas
Step measurement is calculated by measuring the distance between and edge and the next edge above it, using the end of the calipers
After testing out five of the best digital calipers for the UK market, we had to pick a winner. Even though we were surprised by the quality of the more affordable micrometers available like the the Louisware and Moore & Wright Vernier calipers, the real quality instrument is the Mitutoyo 500-196-30. The battery life and hand finishing on the individual parts are more suited to professional use and the exacting requirements needed.
