Vernier Micrometer Screw Gauge

Product Code : SCL-AM-11228

The Vernier Micrometer Screw Gauge from Lab Equipments Ambala is best positioned under Physics Lab / Measurement Instruments / Vernier and Precision Measuring Tools. It supports practical work where students learn pitch, circular-scale reading, main-scale reading, zero error, least count, and corrected measurement of small objects.

Lab Equipments Ambala’s verified physics lab guidance references screw gauge instruments for measurement practicals and separately mentions 0.01 mm screw gauge use in school measurement equipment guidance. A dedicated product page with final product code, measuring range, pitch, least count, accuracy, spindle type, anvil type, frame material, ratchet stop, locking device, protective case, calibration note, packing, and documentation should be confirmed before publishing.

Key Features

• Precision screw measurement: suitable for measuring small thicknesses and diameters where calipers are not sufficiently fine.
• Mechanical reading system: helps students understand main-scale, circular-scale, pitch, least count, and zero-error correction.
• Physics lab compatibility: useful for Class 11 measurement practicals, mechanics experiments, and apparatus familiarisation.
• Workshop and engineering use: supports small-part inspection, wire measurement, sheet measurement, and STEM activities where compatible.
• Manual operation: does not require batteries or electronic display components.
• Controlled contact: may include ratchet stop or friction thimble to reduce over-tightening; final configuration should be confirmed.
• Verification required: range, pitch, least count, spindle/anvil type, frame material, accuracy, and case details must be confirmed from the final specification sheet.

How to Use the Vernier Micrometer Screw Gauge

1. Clean the spindle, anvil, and object surface before measurement.
2. Close the spindle gently against the anvil and check for zero error.
3. Place the wire, sheet, or small object between the spindle and anvil.
4. Rotate the thimble slowly until the object is lightly held without deformation.
5. Use the ratchet stop or friction thimble if supplied to apply consistent measuring pressure.
6. Read the main scale and circular scale according to the confirmed least count.
7. Apply zero-error correction and record the final measurement in millimetres.
8. Repeat readings at different positions if checking roundness, thickness variation, or measurement reliability.

Safety note: Use the Vernier Micrometer Screw Gauge only for suitable small-object measurement. Do not overtighten the spindle, crush soft specimens, drop the instrument, expose it to corrosive chemicals, or use it as a clamp. Store it in its protective case where supplied.

Care & Maintenance

• Keep the spindle, anvil, thimble, sleeve scale, frame, and case clean and dry.
• Wipe the instrument after use to remove dust, oil, moisture, or fingerprints.
• Do not force the thimble beyond the measuring range or tighten the spindle excessively.
• Store the screw gauge in protective packing away from shock, corrosion, heat, bending, and excess humidity.
• Verify zero and recalibrate periodically if used for precision or compliance-sensitive measurement work.

Frequently Asked Questions

What is a Vernier Micrometer Screw Gauge used for?

A Vernier Micrometer Screw Gauge is used to measure small external dimensions such as wire diameter, sheet thickness, rod diameter, and small object thickness with fine mechanical resolution.

Is a micrometer screw gauge the same as a vernier caliper?

No. A vernier caliper is used for broader external, internal, and depth measurements, while a micrometer screw gauge is mainly used for finer external diameter and thickness measurements.

What is the least count of this screw gauge?

Lab Equipments Ambala’s physics-laboratory guidance mentions screw gauge 0.01 mm, but the final least count for this exact product should be confirmed from the product specification sheet.

Does it need batteries?

No. A mechanical micrometer screw gauge uses a screw, sleeve scale, and thimble scale, so it does not require batteries.

Can students use this in physics practicals?

Yes. Screw gauges are used in school and college physics practicals to measure small diameters and thicknesses while teaching pitch, least count, zero error, and corrected reading.

What should be confirmed before ordering?

Confirm product code, measuring range, least count, pitch, accuracy, spindle type, anvil type, frame material, ratchet stop, locking device, case, calibration note, packing, and documentation.
