Key Features
High-strength stainless steel body with waterproof and dirt-proof claim; longer service life than plastic or carbon fiber parts per the listing.
Measuring range 0 to 6 inches / 0 to 150 mm, accuracy ±0.001 inch / 0.02 mm, resolution 0.0005 inch / 0.01 mm; zero button for differential measurements.

One-key switch between inches, fractions, and millimeters on a large LCD readable in strong sunlight.

Design and Build Quality
The caliper body is listed as high-strength stainless steel with waterproof and dirt-proof properties. The listing claims a longer service life than calipers with plastic or carbon fiber parts, but it does not confirm an IP rating or independent certification.
The large LCD is described as easy to read even in strong sunlight. The unit automatically powers off after 5 minutes of non-use, but the listing does not specify the battery type or replacement details.
Performance in Everyday Use
The caliper offers a measuring range of 0 to 6 inches or 0 to 150 mm. Its claimed accuracy is ±0.001 inch or 0.02 mm, and its resolution is 0.0005 inch or 0.01 mm. A zero button supports differential measurements from any point.
One limitation is that the waterproof and dirt-proof claim is not backed by a stated IP rating or lab test in the listing. Users who need certified protection in wet or dusty conditions should verify this before relying on the tool.
