Vernier Calliper Stainless Steel

Product Description

The STEMAids Stainless Steel Vernier Calliper combines a graduated main scale with a sliding vernier scale. The outside jaws measure thickness, width and external diameter. The smaller inside jaws measure internal openings, while a depth rod can measure holes and recesses when included in the supplied configuration.

Its stainless-steel construction is suitable for repeated educational and laboratory handling. Reading the instrument requires the user to identify the main-scale value and add the aligned vernier-scale value. This manual process helps students understand least count, zero error, measurement uncertainty and correct instrument alignment.

Key Features

• Stainless-steel construction: Provides a rigid measuring body for repeated laboratory and workshop use.
• Mechanical vernier scale: Allows measurements without a battery or electronic display.
• Multiple measurement functions: Supports external, internal and depth measurements when the corresponding measuring surfaces are provided.
• Direct measurement training: Helps students learn main-scale readings, vernier coincidence and zero-error correction.
• Sliding jaw mechanism: Positions the measuring faces around or inside compatible specimens.
• Fine dimensional comparison: Supports comparison of rods, tubes, blocks and laboratory components.
• Reusable teaching instrument: Suitable for repeated practical sessions when cleaned, checked and stored correctly.

How to Use the Stainless Steel Vernier Calliper

1. Clean the measuring faces and the surfaces of the object.
2. Close the outside jaws gently and check for positive or negative zero error.
3. Select the outside jaws, inside jaws or depth rod for the required measurement.
4. Position the calliper squarely against the surfaces being measured.
5. Move the sliding jaw until the measuring faces make light, even contact.
6. Record the main-scale reading immediately before the vernier zero.
7. Identify the vernier division that aligns with a main-scale division.
8. Calculate the final reading and apply any verified zero-error correction.

Handling note: Do not force the jaws, measure rotating components or use the calliper as a clamp, divider, scriber or lever. Confirm calibration status before using results for formal inspection or quality-control decisions.

Care & Maintenance

• Wipe the scale, jaws and depth rod with a clean, lint-free cloth after use.
• Store the calliper loosely closed in a dry protective case.
• Do not drop the instrument or file, grind or modify its measuring faces.
• Check zero and compare the instrument periodically against an appropriate dimensional reference.

Frequently Asked Questions

What is a stainless steel vernier calliper used for?

It is used to measure external dimensions, internal dimensions and depth. Common examples include rod diameter, plate thickness, tube bore and hole depth.

What is the measuring range of this vernier calliper?

The measuring range is not confirmed for this STEMAids model. Verify the maximum jaw opening and depth capacity before ordering.

What is the least count of the calliper?

The least count depends on the main-scale and vernier-scale graduations. It must be taken from the approved product specification or verified directly from the instrument.

Does a vernier calliper require a battery?

No. A mechanical vernier calliper uses engraved scales and does not require electrical power.

Can it measure internal diameter and depth?

It can measure internal diameter using the inside jaws and depth using the depth rod, provided those components are included in the supplied configuration.

Does the product include a calibration certificate?

A calibration certificate is not confirmed as standard. Buyers requiring traceable calibration should specify the certificate, measurement points and acceptance criteria when requesting a quotation.
