The best digital calipers deliver exceptionally accurate measurements as a core feature. A silky-smooth slide action is essential. They can take accidental drops, and still look decent enough to be featured on Instagram next to your coffee mug as well as technical drawings.
Although testing became more technical, that formed our rough criteria list when reviewing a range of 150 mm models in the 2021 test. The best digital calipers from nine leading options were put through their paces in the Sheffield workshop. Before diving into the test results, consider the key features to look for when choosing one.
Factors to check while selecting the best digital calipers
One of the main factors is measuring range. For this evaluation, the focus stayed on 150 mm sizes as the most common and readily available. However, versions with ranges up to 2000 mm are widely available, so think about future uses and required sizes. The best digital calipers also excel in resolution, the smallest unit or size change they can register. Most current models offer 0.01 mm, which suits most applications. One standout reaches 0.001 mm.
Repeatability refers to the deviation expected when measuring an object more than once under identical conditions by the same person using the same method. IP rating shows the degree of protection against dust and liquids. This remains a key aspect of the durability of the best digital calipers and the environments in which they are used.
Functions such as data output plus incremental measuring rank as vital considerations for selecting the right tool. Carefully assess the specific capabilities required from the best digital calipers.
In the evaluation process, calibrated gauge blocks helped check the accuracy and repeatability of every model while also weighing durability, cost, available features, handling, and appearance. Now the findings from assessing the best digital calipers can be explored.
1. Best Digital Calipers - Insize 1112 Series
One of the best digital calipers for shop floor work is the Insize 1112 Series, a precision instrument for external, internal, depth and step measurements. It is made with durable stainless steel and rated DIN 862, so you know you'll get the same results day after day. It is used by machinists, technicians, and quality control inspectors in CNC machine shops, auto part inspections, production lines and quality control labs. If you work to precise tolerances, this digital caliper gives you quick and accurate readings, free of the guesswork of an analog scale. The readouts can be switched between metric and imperial and are clearly shown on the large LCD screen in 0.01 mm or 0.0005 in resolution at the click of a button.
You can set the caliper to zero anywhere, so comparison checks are quick and simple. The slider moves smoothly so you can position the jaws exactly where you want them. The tool also powers itself off to save battery but powers back on when you move the slider. These little details make this digital caliper easy to use throughout long manufacturing shifts.
The Insize 1112 Series is available in three different lengths with an accuracy of ±0.03 mm. The 1112-150 (0–150 mm / 0–6 inch) works well for small parts and everyday workshop tasks. The 1112-200 (0–200 mm / 0–8 inch) is good for medium-sized machined parts. The 1112-300 (0–300 mm / 0–12 inch) gives you reach when working with shafts, housings and long profiles. Choose the length that fits your usual component size, and you'll have one of the best digital calipers that feels good in your hand.
Depending on the batch of the device, it can be powered by either a CR2032 or LR44 battery, so check the battery compartment before buying a replacement. SPC data output is available with an auxiliary cable that is sold separately. The 1112 Series is not water- or coolant-proof. If you work around coolant, keep it clean and dry, or get an IP-rated digital caliper. If you're looking for the best digital calipers for accurate everyday inspection at an affordable cost, the Insize 1112 is a good choice.
2. Digital Vernier Caliper Insize 1108
To find the best digital calipers, make sure that they are accurate, durable and that you can record measurements easily. In this category, the Insize 1108 Series ticks all three.
It accurately measures outside, inside, depth and step dimensions with one instrument, and it conforms to the DIN 862 standard.
The solid stainless steel body and precision jaws are suitable for use in tool rooms, production areas, workshops, inspection stations and laboratories. Unlike a manual vernier, the digital display on this caliper lets the operator verify a shaft, hole, sheet or part dimension without squinting at the scale. What makes the 1108 Series unique is the integrated data output. Instead of recording measurements on paper, you can send the results directly to your computer or inspection system, saving time on in-process and batch inspection.
To make data transfer wireless, simply pair an optional 7315-25 transmitter with a receiver.
With 0.01 mm or 0.0005 in resolution, the LCD readout is easy to use, and you can switch between metric and imperial units with one click. Zero at any point on the scale for quick comparison against any drawing. An auto power-off function extends the CR2032 battery life. The Insize 1108 Series comes in three ranges.
The 150 mm version (0–150 mm / 0–6 in) offers the best accuracy at ±0.02 mm. It is ideal for holes, rods, small parts, fasteners, sheet material and production components. The 200 mm (0–200 mm / 0–8 in) and 300 mm (0–300 mm / 0–12 in) models measure bigger parts with an accuracy of ±0.03 mm, and they will not disappoint.
3. Mitutoyo Caliper-500 Series - 500-196-30
If you are narrowing down the best digital calipers for daily use in your shop, consider the Mitutoyo 500-196-30 (CD-6" ASX) 0–150 mm (0–6 inch) digital caliper. This Mitutoyo digital caliper features the company's ABSOLUTE AOS encoder and origin memory that instantly displays the true position when switched on, with no need to re-zero. You can measure outside, inside, step and depth dimensions with a single instrument, making it one of the most trusted digital calipers for machinists, inspectors and engineers who need quick, consistent results on small-to-medium parts.
It measures at a resolution of 0.01 mm (0.0005 inch) and has a maximum permissible error of 0.02 mm (0.001 inch). The large LCD has 9 mm high digits, so you can read measurements at arm's length. The AOS induction sensor is less affected by dirt, water, and oil than conventional sensors, which makes it more dependable in everyday workshop use.
