Moore and Wright Dial Calliper review

These dial callipers arrived promptly and well-packed; the callipers themselves were in a fitted plastic case, inside a cardboard sleeve, inside a cardboard box. Once unwrapped and in hand, it was immediately obvious that they’re a quality item. Sliding the calliper open and closed felt incredibly smooth, and puts to shame many of the £10 internet-ordered digital callipers we’ve had over the years! We went with the yellow-faced, high-contrast dial, which is easy to read and has prominent markings.

As is common to most callipers, these have a locking bolt to hold the jaws of the calliper in a certain position, but they also have another screw mechanism under the dial bezel to be able to zero the dial graduations. It’s a simple procedure to zero the dial: loosen the bolt, ensure the calliper jaws are clean, close the jaws, rotate the bezel so that the dial’s zero mark aligns with the needle, and then re-clamp the bezel bolt. This method of zeroing also means you can zero the dial at a particular reference point if needed.

The callipers are made of good-quality steel, and the jaws are hardened and ground to a high-precision finish. There are the usual internal and external jaws, and also the depth rod for measuring heights and depths. Measuring on these callipers is very straightforward. The nearest millimetre graduation is read off the ruler scale marked along the calliper, and the dial is marked with 100 graduations, each representing 0.02 mm. This means that a single rotation of the dial results in 2 mm of travel.

The dial is nicely marked with every 1/10th of a millimetre labelled 0.1, 0.2, 0.3, etc., and restarts at 0 for the second millimetre of travel. It becomes second nature to read this dial to 0.02 mm very quickly and, while accuracy may vary, it’s possible to predict roughly the third decimal place as to how far between 0.02 mm markings you are. If you need accuracy to thousandths of a millimetre though, you probably need to move beyond callipers! As mentioned, the set we have reviewed are the 150 mm option, but a 300 mm version is also available.

At a little over £40 plus VAT, we feel these callipers are accurate, well-made, and extremely nice to use, with the added bonus that they will never have run out of batteries when you need them most. Couple that with a company that offers great customer service and prompt delivery.
