Vernier Calliper Stainless Steel

Quick answer: This Vernier Calliper is made of stainless steel and is used to measure external, internal and depth dimensions of small objects with much greater precision than an ordinary ruler, using a main scale and a sliding vernier scale.

Description

The LabEquip Vernier Calliper features external jaws for measuring the outer dimensions of an object, internal jaws for measuring the inner dimensions of holes or cavities, and a depth rod for measuring the depth of holes or recesses. Its stainless steel construction resists corrosion and everyday wear better than lower-grade metals, which matters for an instrument that is handled frequently in a busy lab or workshop.

Reading a vernier scale accurately is a core skill taught in school and college physics and workshop-practice classes, introducing concepts such as least count, vernier constant, and reducing observational error compared to a plain scale.

Care & Maintenance

Wipe the jaws clean after use and store the calliper in a dry place to prevent residue build-up affecting accuracy. Avoid dropping it, as impacts can bend the jaws and introduce measurement error, and periodically check for zero error before taking readings.

Frequently Asked Questions

What can a vernier calliper measure that a ruler cannot?

It can measure external dimensions, internal dimensions (such as the inside diameter of a pipe) and depth, all with much finer precision than a plain ruler, using the vernier scale to read fractions of the smallest main-scale division.

What is the least count of this calliper?

The exact least count is not specified for this listing. Please contact our sales team to confirm the specification before you order.

Why is stainless steel used for this instrument?

Stainless steel resists corrosion and wear from frequent handling, helping the calliper’s jaws and scale stay accurate and legible over years of classroom or workshop use.

What is “zero error” and why should I check for it?

Zero error is a small offset in the reading when the jaws are fully closed; checking for it before use and adjusting your readings accordingly keeps your measurements accurate.

What subjects or classes typically use a vernier calliper?

It is standard equipment in secondary and higher-secondary physics, as well as engineering and workshop-practice courses, wherever precise length measurement is taught.

How should I store the calliper between uses?

Wipe it clean, close the jaws gently, and store it in a dry case or drawer away from moisture and heavy tools that could bend the jaws.
