What to know before buying

Listing details to confirm

Listing details are contradictory or unconfirmed: the main details and feature copy state 200mm range, ±0.02mm accuracy and 0.02mm graduation, while the technical information also gives a 150mm/200mm range, ±0.01mm accuracy and 0.01mm resolution. Battery information also conflicts, with one section listing one included CR2032 and another claiming two batteries, one installed and one spare. Confirm the selected listing's accuracy, resolution, range and battery contents before purchase. The IP54 rating is a listing claim, not a basis for immersion or use outside stated conditions.

Frequently asked questions

What is the stated measuring range?

The main product details list a 200 millimetre range. A separate technical section gives both 150mm and 200mm options, so confirm the selected version.

What accuracy does the listing specify?

The main details state ±0.02mm, but another technical section claims ±0.01 mm. Treat the accuracy as unresolved and verify it before precision work.

Does it measure in inches as well as millimetres?

Yes. The listing describes switching between mm and inch units.

What is included?

The explicit included-components list names the caliper, one screwdriver, one CR2032 battery and one portable storage case. Another section claims two batteries and also mentions a manual, so check the selected listing's package contents.
