What it is and who it's for

The HARDELL digital caliper is a 12-inch stainless steel measuring tool with a large LCD screen. It suits mechanics, woodworkers, jewellers, craftsmen, DIY enthusiasts and auto technicians who need reliable outside, inside, depth and step readings in one instrument.

Practical limits of the interface

The caliper measures from zero to 12 inches or 300 millimetres with a stated accuracy of ±0.04 millimetres and a resolution of 0.01 millimetres. The 14 by 40 millimetre LCD shows inches, millimetres and fractions, and the unit powers down automatically after five minutes of inactivity to conserve the two included LR44 cells.

The spec that decides fit

The 12-inch range sets the maximum workpiece size this tool can handle. If your projects regularly exceed 300 millimetres, you will need a longer caliper; otherwise this model covers the full span of typical bench and workshop tasks.

Questions about this item

Which measurement range should I pick — the 12 inch or the 6 inch version?

The listing specifies a 12 inch measuring range (300 mm), so choose that version if you need the full span.

What does the ±0.04 mm accuracy mean when I use the caliper on a real part?

Any reading can deviate by up to four hundredths of a millimetre from the true dimension.

What interface or standard does the caliper use, and what does it limit in practice?

It uses a direct LCD readout with 0.01 mm resolution, so the smallest step you can see is one hundredth of a millimetre.
