Micrometer
Product Code : LSK-PL-10372
Micrometer (SKU LSK-PL-10372), also called a micrometer screw gauge, measures small thicknesses and diameters from 0 to 25 mm in 0.01 mm steps. It suits Class 11 physics practicals, college labs and technical training. Science Lab Supplies turns out the gauge in its Saha, Ambala factory at Plot 448, HSIIDC Industrial Area, India, and quotes it directly to schools, colleges, tender contractors and distributors.

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 returns in B.Sc. elasticity experiments and in ITI and diploma measurement training.
- Class 11 physics: diameter of a given wire, for example a length cut from a 100 g spool of SWG Steel Wire (100gm), and thickness of a given sheet.
- Finding pitch, least count and zero error of the screw gauge.
- B.Sc. practicals: measuring wire diameter before a Young's modulus run on the Young's Modulus Apparatus (Searle's Pattern) or a rigidity experiment.
- 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. Wire samples, calipers or other measuring items for the same practical can be added as separate lines 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, and its accuracy at 10 mm is ±0.003 mm, which is enough for wire and sheet measurements in school and college practicals.
Is a micrometer the same as a screw gauge?
Yes. In school physics the instrument is 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?
This screw gauge is made at the company's own Ambala factory in Saha, Haryana, so Science Lab Supplies is its manufacturer, 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 the stainless steel measuring rod between practical sessions and keeps a class set together on the shelf.
