Stainless Steel Slide Caliper

Product Code : SCL-AM-11250

The Stainless Steel Slide Caliper is a mechanical measuring instrument used to determine the external and internal dimensions of laboratory specimens and engineering components. It is suitable for students, teachers and technicians who require a reusable manual tool for dimensional measurement, comparison and practical instrument-training activities.

Product Description

The instrument consists of a graduated beam, a fixed jaw and a movable sliding jaw. The larger jaw faces are used for outside measurements such as width, thickness or external diameter. The smaller upper jaws, where provided, are used to measure internal openings such as holes, rings and tubes.

The stainless steel construction provides a rigid measuring frame suitable for routine laboratory and workshop handling. Unlike an electronic caliper, a mechanical slide caliper requires no battery. The exact reading method may use a plain graduated slide or a vernier scale, depending on the supplied model.

Key Features

• Stainless steel construction: Provides a rigid and durable measuring body.
• Mechanical operation: Requires no battery, display or electrical power.
• External measurement: Suitable for thickness, width and outside-diameter measurements.
• Internal measurement: Compatible models can measure holes and internal openings.
• Sliding jaw: Allows controlled adjustment to the measured component.
• Graduated beam: Provides a direct manual indication of dimension.
• Portable format: Suitable for laboratory benches, classrooms and workshops.
• Educational value: Helps learners understand dimensional measurement and manual scale reading.

Applications / Uses

• Measuring the external diameter of rods, cylinders and laboratory specimens.
• Measuring the thickness of plates, blocks and mechanical components.
• Determining the internal diameter of tubes, rings and holes when internal jaws are provided.
• Comparing dimensions during manufacturing and workshop exercises.
• Supporting practical measurement work in physics laboratories.
• Inspecting components used in applied mechanics experiments.
• Measuring samples used in properties of matter experiments.
• Teaching instrument handling, zero-error checking and manual scale reading.

How to Use the Stainless Steel Slide Caliper

1. Clean the measuring faces and the surface of the specimen.
2. Close the jaws gently and check whether the instrument reads zero.
3. Record any zero error according to the instrument-reading procedure.
4. Open the larger jaws and position them around the object for an external measurement.
5. Close the jaws gently until both measuring faces touch the object.
6. Use the smaller upper jaws for an internal measurement when that feature is provided.
7. Keep the caliper square to the measured surfaces to reduce alignment error.
8. Lock the movable jaw if a locking screw is available.
9. Read the main and vernier scales, or the relevant graduated slide, according to the model.
10. Record the value together with its unit and instrument least count.

Handling note: Do not force the jaws, use the caliper as a clamp or measure a moving component. Excessive pressure can distort the reading or damage the measuring faces.

Care & Maintenance

• Wipe the measuring surfaces with a clean, dry cloth after use.
• Keep the slide free from abrasive particles, moisture and corrosive chemicals.
• Apply only a light protective film suitable for precision tools when required.
• Store the caliper closed loosely in its protective case without clamping the jaws tightly.

Frequently Asked Questions

What is a Stainless Steel Slide Caliper used for?

It is used to measure external dimensions and, where internal jaws are provided, the internal dimensions of laboratory and engineering components.

Is a slide caliper the same as a vernier caliper?

A vernier caliper is a type of slide caliper that uses a vernier scale for finer readings. Some basic slide calipers use only direct graduations, so the supplied scale type should be confirmed.

Does this caliper require a battery?

No. A mechanical stainless steel slide caliper operates without a battery or electronic display.

Can it measure depth?

Only models fitted with a depth rod or depth blade can perform depth measurements. Confirm whether this feature is included.

What is the measuring range of this caliper?

The range is model-specific and must be confirmed. A 0–150 mm range should not be assigned unless it appears in the supplied specification.

Does the caliper include a calibration certificate?

A calibration certificate is not assumed. Buyers requiring traceable calibration should state the required certificate and acceptance criteria in their enquiry.
