Analogue Caliper Manufacturer,Supplier and Exporter in India
Product Code : EL-AELE-12912
Jlab Export is a leading Analogue Caliper Manufacturer,and suppliers in India
An analogue caliper is read straight from engraved scales, with no display or power supply. This one is a vernier caliper with a 0 to 150 mm range that takes outside, inside, depth and step measurements. Its scales are graduated in both millimetres and inches, so it serves metric parts and imperial tube sizes alike.

Vernier Practicals for Students
The classic physics practical is to find the least count, check the zero error and then measure the diameter of a small sphere or cylinder. Students go on to the internal diameter and depth of a beaker or a short tube, using the inside jaws and the depth bar. They compare each result with a measurement from a Steel Rule to see how much the vernier adds.
In an engineering workshop, the same caliper checks copper tube before flaring and turned parts after machining. Teachers can have students read one part on this caliper, on the Digital Caliper and on an External Micrometer, then discuss why the three readings differ.
Frequently Asked Questions
How do I find the least count of a vernier caliper?
Divide the value of one main-scale division by the number of divisions on the vernier scale. Work it out separately for the millimetre and the inch scale before taking the first reading.
How is a reading taken?
Note the last main-scale mark before the vernier zero. Then look along the vernier for the one line that meets a main-scale line exactly. Its number times the least count is added to the first figure.
What is zero error and how do I correct it?
Close the jaws and look at the two zeros. If the vernier zero sits to the right of the main-scale zero, the error is positive and is taken off every reading. If it sits to the left, the error is negative and is added.
How does parallax spoil a vernier reading?
If the scale is viewed at an angle, a vernier line seems to meet a different main-scale line. Students then pick the wrong coinciding line and record a wrong reading. Hold the caliper so the eye looks straight down on the scales.
Can it measure in inches?
Yes. It carries millimetre and inch graduations, so the same caliper reads metric drawings and imperial refrigeration tube sizes. Use the least count that belongs to the scale you are reading.
