Resolution and accuracy are different numbers, often confused · review
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.
What the figures leave us with The workshop-conditions caliper. Glass scale and IP54 answer real problems; the missing tolerance figure is the price.
A caliper specified against the environment rather than against the part.
A specially processed glass grating scale, stated to prevent the accuracy of the caliper being affected by ambient humidity and magnetism, with a built-in over-speed chip. A Teflon scale strip described as resistant to high and low temperatures, corrosion and friction. A zinc-alloy measuring head and a thickened rule body in hardened, fine-ground stainless steel at around 3.6 mm (0.14 in). IP54 double protection against dust, water spots and oil, with an explicit instruction not to use it in water. One-button metric and imperial conversion, and a zero key.
Most digital calipers read position capacitively, and capacitive scales are sensitive to exactly what a workshop has: moisture films, oil, and magnetized steel. The symptom is not a broken caliper — it is a caliper that reads confidently and wrongly, or jumps a millimeter when slid. An optical glass scale is the standard answer, and it is normally found much higher up the price range.
No accuracy figure. For a tool sold on measurement integrity, that is the specification you would most expect to see, and it is not there.
No such listing: the American Amazon shop answers the reference with a search box rather than a page.

An optical scale read by a sensor, rather than the capacitive strip most digital calipers use. ORTHLAND states it prevents accuracy being affected by ambient humidity and magnetism — the two things that make a cheap caliper jump or drift in a real workshop.
A capacitive caliper slid quickly can lose track of its position and read wrong afterwards, silently. The maker states an over-speed chip guards against that.
No. The maker states IP54 protection against dust, water spots and oil, and adds explicitly not to use it in water. IP54 is splash resistance, not immersion.

A workshop where oil, swarf and damp are normal and a capacitive caliper keeps misbehaving.

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.
