Vernier Caliper Stainless Steel (0.02mm)

Product Code : SCL-AM-12112

The Vernier Caliper Stainless Steel (0.02mm) is a precision manual measurement instrument used for calculating exact internal dimensions, external diameters, depth profiles, and step distances in laboratory and industrial workshops. Designed for students, educators, and technicians, this durable metrology tool delivers micro-precise readings down to 0.02mm without the need for electronic power sources.

Product Description

The Vernier Caliper Stainless Steel (0.02mm) from Science Lab Supplies is manufactured from fully hardened stainless steel to provide maximum structural rigidity and exceptional resistance to physical wear. The tool features clear, precision-engraved graduation lines set against a non-glare satin chrome finish, which protects the scales from micro-scratches and minimizes visual glare under heavy laboratory lighting. The slider mechanism operates smoothly across the beam, eliminating lateral play to provide highly repeatable measurement values.

This analog metrology instrument serves as an essential teaching foundation for physics, engineering, and vocational training courses. By requiring users to manually evaluate the vernier scale alignment, it builds necessary analytical skills and demonstrates the concept of least count calculation. This permanent, battery-free addition to your physics lab equipment array remains fully operational over decades of educational use.

Key Features

• Hardened Stainless Steel Frame: Built entirely from heavy-gauge, hardened steel alloy to prevent warping, bending, and structural distortion over time.
• 0.02mm Least Count Resolution: Features a highly accurate metric scale block that enables measurements down to a twentieth of a millimeter.
• Dual Scale Readings: Equipped with clear metric and imperial graduation lines to support simultaneous measurements in millimeters and fractions of an inch.
• Four-Way Measuring Utility: Precision-ground jaw profiles allow users to calculate external diameters, internal bore openings, structural steps, and cavity depths.
• Satin Chrome Vernier Plates: High-contrast scale plating eliminates reflection and enhances visual legibility during detailed readings.
• Integrated Knurled Locking Screw: Features a top-mounted manual locking clamp to hold slide positions fixed for field transcription.

How to Use the Vernier Caliper Stainless Steel (0.02mm)

1. Zero Verification: Clean the measuring faces completely. Slide the jaws shut and verify that the '0' mark on the vernier scale aligns perfectly with the '0' mark on the main beam scale.
2. Position the Object: Place your sample between the lower jaws for external measurements, or use the upper inverted jaws inside an open bore for internal measurements.
3. Secure the Slide: Move the sliding scale smoothly until the jaw faces firmly grasp the component surfaces. Tighten the knurled lock screw lightly to secure the measurement.
4. Read the Main Scale: Note the main scale line situated immediately to the left of the vernier scale's zero mark to establish whole millimeter values.
5. Read the Vernier Scale: Identify the specific line on the fractional vernier scale that lines up perfectly with a graduation line on the main scale beam. Multiply this line number by 0.02mm.
6. Sum the Totals: Add the main scale value and the fractional vernier value together to get your final measured dimension.

Handling Note: Always ensure the locking screw is completely loosened before sliding the jaw assembly to avoid abrasive friction wear along the satin scale faces.

Care & Maintenance

• Surface Cleaning: Wipe the caliper down with a soft, dry microfiber cloth after every laboratory session to remove skin oils, dust particles, and moisture.
• Lubrication: Apply a thin layer of fine white industrial instrument oil to the sliding beam surfaces every six months to maintain smooth operation.
• Secure Storage: Keep the caliper placed inside its custom padded storage box when not in use to protect the precision jaw alignment from accidental work bench drops.

Frequently Asked Questions

What does the 0.02mm value represent on this manual vernier caliper?

The 0.02mm value represents the instrument's least count or resolution, which is the smallest physical change in dimension that the mechanical vernier scale can reliably differentiate.

Why is an analog caliper preferred over a digital model in science classrooms?

An analog caliper is highly valued in educational settings because it operates permanently without battery cells and requires students to actively read the mechanical scale matrix, reinforcing essential math and physical measurement concepts.

Can this stainless steel caliper measure the depth of blind holes?

Yes, this tool contains a built-in flat depth rod linked to the main slider that emerges from the rear end of the beam, allowing easy measurement of internal pocket depths.

What should I do if the vernier scale zero line does not align perfectly at zero?

Ensure there are no dust particles caught between the flat measuring jaws. If it remains misaligned after cleaning, note the structural zero error value and subtract or add it to your final experimental calculations.

Does the stainless steel construction resist rust in chemical environments?

The caliper is fabricated from high-grade hardened stainless steel, which provides excellent resistance to standard moisture and corrosion, though it should be wiped clean immediately if exposed to acidic or caustic chemicals.
