Carbon Steel Pocket Vernier Caliper with Open Block

Product Details

This pocket vernier caliper is a carbon-steel inspection tool for external, internal, and depth measurement. Three dual-unit models cover 0-150 mm / 0-6", 0-200 mm / 0-8", and 0-300 mm / 0-12" at 0.02 mm / 0.001" resolution. An open-block beam with a top locking screw is read from a metric/inch vernier scale.

Model Comparison

Detailed Description

The measuring beam and jaws are carbon steel. The slider is an open-block (movable) assembly locked by a top screw, with dual baffle screws at the tail. A semi-circular thumb grip and a square depth rod support one-handed workshop handling and depth checks.

The scale is a dual metric/inch vernier with centimeter markings. A conversion table is fitted on the reverse of the beam, and a serial number is marked on the reverse of the tail. The tool is a manual vernier instrument without data output.

All three models share the same construction, 0.02 mm / 0.001" resolution, and DIN 862 designation. They differ only by measuring range: 0-150 mm / 0-6", 0-200 mm / 0-8", and 0-300 mm / 0-12". Accuracy is not specified and should not be inferred from resolution. Each piece is packed in a transparent bag inside a black leatherette pouch; inner boxes hold 10 pieces (25 x 10 x 11 cm) and cartons hold 50 pieces (52 x 27 x 12.5 cm).

Selection Advice

Choose 0-150 mm / 0-6" for compact parts. Use 0-200 mm / 0-8" or 0-300 mm / 0-12" when the workpiece is longer. All listed models share 0.02 mm / 0.001" resolution; that value is the smallest scale increment, not a proven accuracy grade. Accuracy is not specified for this family.

Select a manual vernier caliper when a dual-unit scale without electronics is enough. Choose a digital caliper if an LCD or data output is required. For tighter length checks, consider a micrometer; for dedicated hole-bottom or groove depth work, consider a depth gauge.

FAQ

What is the difference between the three models?

The models differ by measuring range: 0-150 mm / 0-6", 0-200 mm / 0-8", and 0-300 mm / 0-12". Resolution is 0.02 mm / 0.001" on all three. Accuracy is not specified.

Is 0.02 mm the accuracy of this caliper?

No. 0.02 mm / 0.001" is the vernier resolution, the smallest increment you can read. Accuracy is not specified and should not be assumed from resolution.

Does this caliper have a digital display or data output?

No. It is a manual vernier caliper without data output. Readings are taken from the dual metric/inch vernier scale.

Can I read both millimeters and inches?

Yes. The beam has dual metric and inch vernier markings, plus centimeter markings. The listed imperial resolution is 0.001".

What packaging is included?

Each caliper is packed in a transparent bag inside a black leatherette pouch with a product label. Inner boxes hold 10 pieces (25 x 10 x 11 cm). Cartons hold 50 pieces (52 x 27 x 12.5 cm).

Can the product be customized?

A serial number is marked on the reverse of the beam tail. Additional OEM marking or packaging should be confirmed with the supplier.
