Units
Inch and millimeter, switched by one button · Zero can be set anywhere along the range
Display
A large LCD, auto on when the rail is slid, auto off after 5 minutes
Stated limit
The maker states plainly that it is not for technical measurement

  • Publishes both resolution and accuracy, so the gap can be read
  • A low-hardness body that will not mark a finished surface
  • Two tenths of a millimeter is coarse for a caliper — ten times the Hardell here

Best for: Checking stock thickness and bit diameters against a finished surface, to a fifth of a millimeter

Every figure below names its source. Each one is a manufacturer specification read off the listing itself. The judgments are ours.

Resolution is not accuracy

A digital instrument has two numbers and they are not the same.

Resolution is the smallest change the display can show. Accuracy is how far the reading may be from the truth. A caliper that displays hundredths and is accurate to two tenths is showing twenty times more precision than it possesses.

The published digital angle gauge on this shelf carries the same gap in its cons — a display reading to 0.05 degrees on an instrument accurate to ±0.2. Reading the second figure is the whole skill, and only the listings that publish both allow it.

Here it is a tenth against two tenths

The display shows 0.1 mm (0.004 in). The accuracy is ±0.2 mm (0.01 in).

So the last digit is decoration, and the instrument is honest enough to publish both figures so that can be seen.

The published Hardell caliper on this shelf is ±0.02 mm (0.001 in) — ten times finer — and its page argues the opposite case: finer than wood moves with the weather.

Both are true. They are different jobs.

Two tenths is enough for timber

Wood moves several tenths across its width with the seasons, so measuring a board to hundredths is measuring the humidity.

What two tenths will not do is set a machine. A router bit diameter, a tenon against its mortice, a bearing fit — those want the finer instrument.

And it will not scratch the work

A low-hardness composite body, stated.

Steel jaws dragged across lacquer or wax leave a mark, and the place a caliper is most used in a workshop is on a part that is nearly finished.

What it costs is stiffness: a plastic jaw flexes under thumb pressure, so a hard squeeze reads small. That flex is part of why the accuracy is two tenths.

Not for technical measurement

The listing says so, in its own fourth feature.

Across both halves of this shelf two listings name their own boundary — this one, and the published Hardell, which says splash resistant is not waterproof.

Naming the limit is what lets a reader buy the right instrument. The rest of this shelf leaves it to be found out.

What comes up most often

Is two tenths of a millimeter good enough for wood?

For most of it, yes — and that is the honest case for this instrument. Timber moves several tenths of a millimeter across its width with the seasons, so measuring a board to hundredths is measuring the weather. What two tenths is not good enough for is machine setting: a router bit diameter, a tenon thickness against a mortice, a bearing fit. The published Hardell caliper on this shelf is ±0.02 mm (0.001 in) and its page makes the opposite point — finer than wood moves with the weather. Both are true; they are different jobs.

What does a plastic body buy?

A finished surface that is still finished afterwards. Steel caliper jaws dragged across lacquer or wax leave a mark, and the one place a caliper is most used in a workshop is on a part that is nearly done. A low-hardness composite body cannot scratch the work. What it costs is stiffness — a plastic jaw flexes under thumb pressure, so a hard squeeze reads small, and that flex is an error nobody publishes. It is why the accuracy figure is two tenths rather than two hundredths.

Why publish “not for technical measurement”?

Because it is true and it saves a return. The listing states it outright, which across both halves of this shelf only two listings do in any form — the published Hardell page says splash resistant is not waterproof, and its own page credits it for saying so. A listing that names the boundary of its product is doing something the rest of the shelf leaves to the buyer, and on an instrument sold at this price the boundary is exactly what needs naming.
