What to know before buying

Listing details to confirm

The listing conflicts or is inconsistent on details: the specifications describe Plastic, Stainless Steel, while feature copy emphasizes stainless steel, and the range is also expressed as 0–6 inches/0–150 mm in feature copy but as 1.5E+2 millimeters in details. A customer summary mentions a display measuring only to 11.9 inches, which does not match this 6-inch model. A case is claimed in feature copy but is absent from the explicit contents list, so its inclusion is unconfirmed. Check the selected listing if these details matter.

Customer feedback describes the caliper as useful for its intended measuring tasks, with positive comments about perceived accuracy, build quality, measurement options and storage. The feedback also says display-size impressions are mixed, including a report that it measures only to 11.9 inches. That stated limit conflicts with this listing's six-inch model identity, so it should not be treated as a confirmed specification. The positive comments are relevant to routine small-part measuring, but do not independently verify the stated accuracy.

Positive themes

Customers describe the tool as working well for its intended purpose and report accurate readings.
Feedback notes positive impressions of build quality, measurement options and storage.

Mixed feedback

Display-size feedback is mixed. A reported 11.9-inch measuring limit conflicts with this product's listed six-inch model.

Frequently asked questions

What measurement range is listed?

The detail field states 1.5E+2 millimeters. Feature copy describes 0–6 inches/0–150 mm. Because the formats differ, confirm the range in the selected listing if it is critical.

What accuracy and resolution does the listing claim?

It lists ±0.03mm/0.001" accuracy and a resolution of 0.0005" / 0.01mm. These are listing claims, not independent measurements.

What can this caliper measure?

The listing describes inner and outer diameter, depth and step measurement using its jaws and probe.

Is a carrying case included?

Feature copy says a case comes with the caliper, but the explicit contents list does not include one. Case inclusion is therefore unconfirmed.
