Resolution and accuracy are different numbers, often confused · review
The only caliper in this hub that names the standard behind its figure: ± 0.02 mm (0.001 in) to DIN 862, with 0.01 mm resolution and the four standard measuring functions.
What the figures leave us with The caliper that specifies itself correctly. Named standard, resolution and accuracy stated apart. That is what the money buys.
One caliper in this hub names a standard. It is this one.
Precise measurements at ± 0.02 mm (0.001 in) to DIN 862, described as ideal for professional applications. A large LCD with 0.01 mm or 0.0005 inch resolution, stated as delivering precise results even in hard-to-reach measuring positions. Four-way measuring function: outside, inside, depth and step. Millimeter and inch switching.
Any manufacturer can print ± 0.02 mm (0.001 in). A standard defines what that figure means: over what range, at what temperature, measured how. DIN 862 does that for calipers. A tolerance quoted against it is a claim with a defined meaning; a tolerance quoted alone is a number.
For most work, either is fine. For a measurement that ends up in a report, on a drawing, or in a dispute, the difference is the whole point.
This listing gives 0.01 mm as the display step and ± 0.02 mm (0.001 in) as the accuracy, in two separate sentences. Elsewhere in this hub the two are merged, omitted, or — on one micrometer — the resolution is called the accuracy outright. Reading them apart is the single most useful habit in this category.
No such listing: the American Amazon shop answers the reference with a search box rather than a page.

The German standard covering vernier and digital calipers, including permissible errors. MIB states its ± 0.02 mm (0.001 in) figure to that standard. We report that as a manufacturer statement — this site does not verify conformity.
Because the figures are not saying the same thing. HARDELL states ± 0.02 mm (0.001 in) as its own claim; MIB states it against a named standard that defines how the figure is established. Whether that difference is worth twenty-five euros depends on whether anyone will ever ask you to justify a measurement.
Yes — 0.01 mm or 0.0005 inch, given separately from the ± 0.02 mm (0.001 in) accuracy. That separation is the mark of a properly written specification and it is rare in this hub.

Work where the measurement has to be defensible, and naming the standard is part of that.
Amazon reports what buyers took in the month before this page was last checked: at least 200.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.
Specifications: the manufacturer sheet for measuring instruments and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
150 mm (5.91 in) · carbon-fiber composite · zero button · mm and inch
A 150 mm (5.91 in) caliper in carbon-fiber composite rather than steel — lighter, and with no accuracy figure published anywhere in the listing.
Best for: Occasional measuring of soft materials — plastic, wood, printed parts — where the jaws will not be abraded.
150 mm (5.91 in) · ± 0.02 mm (0.001 in) stated · hardened stainless · four modes
A hardened stainless caliper stating ± 0.02 mm (0.001 in) over 0–150 mm (0 to 5.91 in), splash and dust protected, with the four standard measuring modes and a zero button.
Best for: The value pick: a published tolerance and hardened jaws, without paying for a named standard.
150 mm (5.91 in) · glass grating scale · IP54 · hardened stainless body
A caliper using a glass grating scale rather than the usual capacitive strip, which the maker states resists humidity and magnetism, in an IP54 hardened stainless body.
Best for: A workshop where oil, swarf and damp are normal and a capacitive caliper keeps misbehaving.
