Vernier Calliper
Vernier Calliper (Product Code: SCL202/01) is a stainless-steel sliding measuring instrument used to measure the length and diameter of small objects more precisely than a ruler in school and college physics practicals. This IME-type calliper is 15 cm long, has a listed least count of 0.01 mm and a thumb movement that slides the jaws smoothly. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for schools sourcing a Vernier caliper in India for class sets.

What Is the Vernier Calliper Used For?
A vernier calliper lets students read a measurement that falls between two graduation marks on the main scale. The sliding vernier scale performs a mechanical interpolation, which increases resolution and reduces the guesswork of estimating by eye – the student simply looks for the vernier line that lines up most closely with a main-scale line. It is a routine item of physics practical equipment for CBSE and state-board laboratories, used to find the diameter of a small sphere or cylinder and the dimensions of a regular block, and from these its volume.
Before measuring, close the jaws and check whether the vernier zero sits exactly on the main-scale zero; note any zero error with its sign. Grip the object gently between the jaws using the thumb movement, read the main scale just before the vernier zero, add the coinciding vernier division multiplied by the least count, and correct for zero error. Repeat at different positions and average the readings.
What to Specify When Ordering
- The number of callipers – usually one per student pair or practical group.
- Confirm that a 15 cm length and the listed 0.01 mm least count match your practical syllabus.
- Whether screw gauges, spheres or blocks for the same experiments should be quoted with them.
Supplier
The Vernier Calliper is supplied by Jain Scientific Equipments Private Limited, the company behind the ScienceLab name in Ambala, Haryana. Physics departments can order it together with the spheres, blocks, scales and screw gauges used in the same measurement practicals, and receive one consolidated quotation. More about the company is available on our company profile.
Related Physics Lab Equipment
Apparatus used alongside the vernier calliper in measurement practicals:
- Screw Gauge — for finer measurements such as the diameter of a wire or thickness of a sheet.
- Steel Ball — a sphere whose diameter and volume students determine.
- Wooden Block Small Size — a regular body for measuring length, breadth and height.
- Bob/Metallic Sphere (Small) With Hooks — measure its diameter to find the effective length of a simple pendulum.
- Meter Scale 100 cm — for lengths beyond the calliper’s range.

Frequently Asked Questions
What is the least count of the Vernier Calliper?
The Vernier Calliper is listed with a least count of 0.01 mm. If your practical syllabus or tender specifies a different least count, mention it in your enquiry so we can confirm the correct instrument before quoting.
How long is the Vernier Calliper and what is it made of?
The Vernier Calliper is 15 cm long and made of stainless steel. It is an IME-type calliper with a thumb movement that lets students slide the jaws smoothly onto the object being measured.
How do I check the zero error of a vernier calliper?
Close the jaws of the Vernier Calliper fully and see whether the vernier zero coincides with the main-scale zero. If it lies to the right, the zero error is positive; to the left, negative. Subtract the zero error from every reading.
Is a calibration certificate available with the Vernier Calliper?
Whether a calibration certificate can be provided with the Vernier Calliper should be discussed with us before ordering. Please raise it through our contact page and we will explain what documentation is available for your order.
Who supplies the Vernier Calliper?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab in Ambala, Haryana, supplies the Vernier Calliper to schools, colleges, laboratories and dealers in India and international markets, as single pieces or class quantities.
What should a quotation request include?
For the Vernier Calliper, quote product code SCL202/01, the number of pieces, any least-count requirement and the delivery location. Send the request through our contact page and we will reply with a quotation.
