Preciva 02-067-2 Digital Caliper, 6-Inch Stainless Steel with LCD

For DIYers, hobbyists and tradespeople who need to measure small dimensions, the Preciva digital caliper brings internal, external, depth and step measurements together in one tool. Its 0–150 mm range and large LCD make it practical for checking component sizes and reading results clearly at the workbench.

Switch between millimetres, inches and fractions with a button, or zero the display at any position to compare measurements. A thumb roller supports smooth adjustment, while the locking screw helps hold a reading in place as you work.

At a glance

The stainless steel caliper measures from 0–150 mm, with readings shown on a large LCD. Its resolution is 0.01 mm, 0.0005 inch or 1/128 inch. Select metric, imperial or fractional units to suit the measurement you’re taking, without having to convert the result separately. The zero function is useful when measuring a difference: set a reference point, then read the change directly on the display.

Use the jaws for external measurements such as a part’s width, the smaller inside jaws for internal dimensions, and the depth rod for recesses or openings. Step measurements are also supported, making the caliper useful across workshop, electrical, hobby and automotive tasks. For example, when fitting a small component, you can check its outside dimension and compare it with an opening using the same tool.

The hardened stainless steel body is described as resistant to rust, dust and splashes. A thumb roller helps with fine positioning, and the locking screw holds the slide steady when you need to retain a measurement. The caliper also has an automatic shut-off after about five minutes of inactivity. The package includes the digital caliper, an LR44 battery, a spare battery, a plastic case, a screwdriver and a user manual.

Buyers often praise the readable display, sturdy construction and measuring performance. Feedback is more mixed on functionality and battery life, and some buyers express dissatisfaction with auto-on behaviour. These are user impressions rather than a substitute for the tool’s stated features.

Who it’s for

This caliper suits people who regularly check small dimensions during DIY projects, hobby work or professional tasks. Its selectable units are helpful when a drawing, part or reference uses a different measurement system from the one you normally work in. The zero function also helps when the goal is to compare a part against a reference rather than record its full size.

If you’re choosing between a basic manual caliper and a digital model, the practical distinction here is the LCD readout and one-button unit conversion. That can make readings easier to read and switch between, while the sliding jaws still support the familiar process of measuring a part directly.

Getting the most from it

Set the jaws or depth rod against the surfaces you want to measure, then use the thumb roller to move the slide into position. Read the display and select millimetres, inches or fractions as needed. To check a difference from a reference, press zero at the chosen starting point and measure from there. When a reading needs to stay in place while you reposition the tool or record the result, tighten the locking screw.

The included case gives the caliper a dedicated place for storage between jobs. Keeping the measuring surfaces clean and using the case helps keep the tool ready for the next small-part measurement. It runs on an LR44 battery, with a spare included, and the automatic shut-off helps conserve power during periods of inactivity.

When it makes sense

It makes sense if you want one digital measuring tool for external, internal, depth and step dimensions, rather than relying on a separate tool for each type of check. The 0–150 mm range, readable LCD and selectable metric, inch and fractional displays support varied work at a bench or in a workshop. For anyone measuring small parts and switching between unit formats, this Preciva caliper brings those tasks together in a compact stainless steel instrument.
