Micrometer
Product Code : LSK-PL-10372
Micrometer (SKU LSK-PL-10372), often called a micrometer screw gauge, measures small thicknesses and diameters from 0 to 25 mm in 0.01 mm steps. It is a standard instrument for Class 11 physics practicals, college labs and technical training. Made by Science Lab Supplies in its own factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, it is offered directly to schools, colleges, tender contractors and distributors.
Specifications
The micrometer has a 0–25 mm range read to 0.01 mm, with a stated accuracy of ±0.003 mm at 10 mm. Its frame is nickel plated brass, the spindle is an accurately machined stainless steel rod, and a ratchet top gives even contact pressure. It is supplied in a case.

Applications and Experiments for the Micrometer Screw Gauge
The screw gauge is used wherever a length is too small for a vernier caliper to read well, such as wire diameter or sheet thickness. It is part of the NCERT Class 11 physics practical list and is used again in B.Sc. elasticity experiments and in ITI and diploma measurement training.
- Class 11 physics: diameter of a given wire and thickness of a given sheet.
- Finding pitch, least count and zero error of the screw gauge.
- B.Sc. practicals: measuring wire diameter for Young's modulus and rigidity experiments.
- ITI and polytechnic workshops: checking small machined dimensions.
Standard Scope of Supply
Each micrometer comes in its own case, with the nickel plated brass frame, stainless steel measuring rod and ratchet top as specified above. Nothing else is listed as standard; any extra items you request are shown separately on the quotation.
Packing, MOQ and Lead Time
Quotations are available for a single micrometer or for a complete batch for a school physics laboratory. Each one lists the packing, delivery time and price for the quantity you name, and vernier calipers, spherometers or rulers can be priced on the same sheet.

Frequently Asked Questions
What is the range and least count of this micrometer?
It measures from 0 to 25 mm with a least count of 0.01 mm. The stated accuracy is ±0.003 mm at 10 mm.
Is a micrometer the same as a screw gauge?
Yes. In school physics the instrument is usually called a screw gauge, because each turn of the thimble advances the measuring rod by one pitch of the screw.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer of this micrometer. It is produced at the company's Ambala factory in Saha, Haryana, and each quotation is issued by the factory without a reseller in between.
Does the micrometer come with a case?
Yes. It is supplied in a case, which protects the ratchet top and measuring faces between practical sessions.
