Resolution and accuracy are different numbers, often confused · review
A hardened stainless caliper over 0–150 mm (0 to 5.91 in) with four measuring methods — and a stated resolution of 0.03 mm (0.001 in), which is coarser than the 0.01 mm step these tools normally display.
What the figures leave us with Solidly built and confusingly specified. The HARDELL below it publishes a real tolerance for less.
Good steel, and a specification line worth reading twice.
A measuring range of 0 to 150 mm (0 to 5.91 in) with a stated resolution of 0.03 mm (0.001 in) and reliable accuracy. High-quality hardened stainless steel, rustproof and splash-protected. A high-resolution LCD. Four measuring methods — inside, outside, depth and step — with conversion between millimeters and inches and a zero function. A CR2032 cell is included.
Nearly every digital caliper at this size displays in steps of 0.01 mm. A stated 0.03 mm (0.001 in) is unusual enough that it deserves an explanation the listing does not give. It may be a tolerance quoted as a resolution, which would be a normal figure described with the wrong word — or it may be exactly what it says. The manual in the box settles it, and it is the first thing to read.
The material is not in doubt: hardened stainless, rustproof, splash-protected, with a thumb wheel for controlled closing pressure. Closing pressure matters on a caliper — squeeze harder and the reading shrinks — and a wheel is what makes two measurements by two people agree.
No such listing: the American Amazon shop answers the reference with a search box rather than a page.

No. Digital calipers in this class almost universally display 0.01 mm steps. Preciva states 0.03 mm (0.001 in). Either the figure in the listing is the tolerance rather than the resolution, or this really is a coarser display than its neighbors — and it is worth reading the manual on arrival to find out which.
Inside, outside, depth and step measurements, with conversion between millimeters and inches.
Not a number. The listing describes measurement-accurate results and reliable accuracy without stating a tolerance.

General workshop measuring where hundredths are not the deciding factor.
Amazon reports what buyers took in the month before this page was last checked: at least 50.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.

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.
± 0.02 mm (0.001 in) to DIN 862 · 0.01 mm resolution · four functions
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.
Best for: Work where the measurement has to be defensible, and naming the standard is part of that.
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.
