Micrometer Screw Gauge, Lock Type
Micrometer Screw Gauge, Lock Type (Product Code: SLE/PHY/246) is a precision hand instrument used to measure small outside dimensions, such as wire diameter or sheet thickness, from 0 to 25 mm in school and college physics laboratories. Built from nickel-plated brass with a ratchet top and a lock, this physics lab instrument reads to 1/100 mm and comes in a plastic case. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is a Micrometer Screw Gauge Used For?
In lab practicals across India, the screw gauge is used to measure the diameter of a wire, the thickness of a glass slide or metal sheet and the diameter of small spheres, each to the nearest 0.01 mm. It handles the wire-diameter step of experiments such as Young's modulus by Searle's method and the resistivity of a wire, and it teaches students about pitch, least count and zero error.
Always turn the thimble using the ratchet top so the same gentle pressure is applied at every reading, and check for zero error by closing the jaws before you start. Once a reading is set, the lock holds the spindle so the value can be read or shown to a teacher without shifting. Wipe the measuring faces clean and keep the gauge in its plastic case between practicals.
What to Specify When Ordering
- The number of gauges, typically one per student pair or group.
- Whether you want this lock-type model or the standard screw gauge also listed in the catalogue.
- Whether vernier calipers should be quoted as well for dimensions above 25 mm.
OEM Manufacturer
Jain Scientific Equipments Private Limited trades as ScienceLab and is the OEM (original equipment manufacturer) of this Micrometer Screw Gauge, Lock Type, produced at the company's own licensed factory at Saha, Ambala, Haryana, India. Because the gauge comes straight from the maker rather than a reseller, schools, colleges, dealers and importers in India and international markets deal directly with the company that produces it. Ask us about repeat orders or replacement cases, and see the ScienceLab company profile for more about the business.

Frequently Asked Questions
What is the least count of the Micrometer Screw Gauge, Lock Type?
The Micrometer Screw Gauge, Lock Type has a precision of 1/100 mm, so it reads to 0.01 mm across its 0–25 mm range. That resolution suits measuring wire diameters, sheet thickness and small spheres in school and college physics practicals.
What is the measuring range of the Micrometer Screw Gauge, Lock Type?
The Micrometer Screw Gauge, Lock Type measures outside dimensions from 0 to 25 mm. For objects larger than 25 mm a vernier caliper is the better choice, and ScienceLab can quote both instruments together for a complete measurement set.
What does the lock on the Micrometer Screw Gauge, Lock Type do?
The lock on the Micrometer Screw Gauge, Lock Type holds the spindle in position once a reading is taken, so the value does not shift while it is read, recorded or checked by a teacher. Release the lock before turning the thimble again.
What is the Micrometer Screw Gauge, Lock Type made of?
The Micrometer Screw Gauge, Lock Type has a nickel-plated brass body with a ratchet top and an accurately machined stainless steel rod. It is supplied in a plastic case that protects the measuring faces between practicals.
Who manufactures the Micrometer Screw Gauge, Lock Type?
The Micrometer Screw Gauge, Lock Type is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer with its own licensed factory at Saha, Ambala, Haryana, India. Schools and dealers buy it factory-direct, with quotations issued by the manufacturer.
