Product Code : EL-MI-2114
Jlab Export is a leading Micrometer Screw Gauge Manufacturer,and suppliers in India
Micrometer Screw Gauge (code EL-MI-2114) is an economical Welch-pattern screw gauge with a semicircular frame, used to measure the diameter of wires and the thickness of thin sheets in school and college physics practicals. It is listed in 15, 20 and 25 mm sizes with a 1 mm or 0.5 mm screw pitch, and each gauge is boxed with a working manual. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Screw Gauges?
| Model | Sizes (as listed) | Construction | Packing |
|---|---|---|---|
| This screw gauge (EL-MI-2114) | 15, 20 or 25 mm; 1 mm or ½ mm | Welch-pattern semicircular frame, dull nickel finish, oxidized threaded rod | Cardboard box with working manual |
| Screw Gauge Micrometers | 25 mm x 1 mm pitch | Brass body, dull nickel plated; machined stainless steel screw | Sold individually; inner pack of 10 |
| Lock Type Micrometer Screw Gauge | 25 mm x 0.01 mm reading | Nickel-plated brass, ratchet top, machined stainless steel rod | Plastic case |
| Micrometer Moore and Wright | 25 x 1 mm or 25 x ½ mm | Hardened stainless steel, ground threads, locking arrangement | Velvet-lined case |
Choose this gauge for class sets where an economical instrument is enough and where a shorter 15 or 20 mm size suits the work. The lock-type gauge adds a ratchet top and a stated 0.01 mm reading, and the stainless steel models suit buyers who want a harder screw.
What Is the Micrometer Screw Gauge Used For?
A screw gauge turns rotation of a finely threaded spindle into a small, measurable advance: one full turn moves the spindle by one pitch, and the divisions on the thimble split that pitch into fractions. Its least count is therefore the pitch divided by the number of thimble divisions. In CBSE and ICSE class 11 physics practicals it is used to find the diameter of a given wire and the thickness of a sheet, and it appears in the measurement chapter of ICSE class 9 physics, in first-year college physics labs and in ITI trade training.
Before taking readings, bring the spindle gently onto the anvil and note any zero error. Turn the screw in one direction only while closing on the object, so that backlash in the thread does not enter the reading, and average readings taken at several points. Store the gauge in its box with the faces clean.
What to Specify When Ordering
- Size and pitch — 15, 20 or 25 mm, with a 1 mm or ½ mm pitch, as listed above.
- Quantity — the minimum order is 10 gauges.
- Companion instruments — a vernier caliper and a spherometer complete the usual set of measuring practicals and can be quoted together.
Frequently Asked Questions
What is the least count of this screw gauge?
The listing does not state it. The least count equals the screw pitch divided by the number of divisions on the thimble, so it depends on the size and pitch you order; ask JLab for the thimble divisions when you request a quote.
What do the sizes such as 25 x ½ mm mean?
The first figure is the measuring length and the second the screw pitch, the same way JLab lists its other screw gauges. Confirm the size and pitch you need in your enquiry.
Is it accurate enough for school practicals?
Yes for teaching use: it is described as sufficiently accurate for beginners and for most elementary laboratory measurements. For work that needs a stated 0.01 mm reading, the lock-type gauge in the comparison above is listed with that precision.
How does it differ from the Screw Gauge Micrometers model?
That model is listed in one size, 25 mm with a 1 mm pitch, with a brass body and a machined stainless steel screw. This gauge has a Welch-pattern semicircular frame and an oxidized threaded rod and comes in six size and pitch combinations.
Who manufactures this screw gauge?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
The gauge comes from Jain Laboratory Instruments Pvt Ltd, trading as JLab, a manufacturer of physics lab instruments in India that was incorporated in 2017 and works from Hargolal Road, Ambala, Haryana. JLab produces it in its own workshop instead of buying it from a trader, so dealers, importers, schools and colleges get factory-direct supply, each gauge is inspected by eye before boxing, and repeat orders come back to the same maker. JLab exports worldwide and ships to buyers in every region — for example Mexico in North America, Luxembourg in Western Europe, South Africa in Southern Africa, Chad in Central Africa and Libya in North Africa. Tender buyers can find details on the lab tenders page.
