For example is a pH-meter.
A Vernier allows a precise reading of some value. In the figure to the right, the Vernier moves up and down to measure a position on the Scale. This could be part of a barometer which reads atmospheric pressure. The "pointer" is the line on the vernier labelled "0". Thus the measured position is almost exactly 756 in whatever units the scale is calibrated in. If you look closely you will see that the distance between the divisions on the vernier are not the same as the divisions on the scale. The 0 line on the vernier lines up at 756 on the scale, but the 10 line on the vernier lines up at 765 on the scale. Thus the distance between the divisions on the vernier are 90% of the distance between the divisions on the scale. If we do another reading with the vernier at a different position, the pointer, the line marked 0, may not line up exactly with one of the lines on the scale. Here the "pointer" lines up at approximately 756.5 on the scale. If you look you will see that only one line on the vernier lines up exactly with one of the lines on the scale, the 5 line. This means that our first guess was correct: the reading is 756.5. Here is a final example, with the vernier at yet another position. The pointer points to a value that is obviously greater than 756.5 and also less than 757.0. Looking for divisions on the vernier that match a division on the scale, the 7 line matches fairly closely. So the reading is about 756.7. In fact, the 7 line on the vernier appears to be a little bit above the corresponding line on the scale. The 8 line on the vernier is clearly somewhat below the corresponding line of the scale. So with sharp eyes one might report this reading as 756.73 ± 0.02. This "reading error" of ± 0.02 is probably the correct error of precision to specify for all measurements done with this apparatus. Now we shall use a simulation of a Vernier Caliper. A caliper measures a length, and in the following figure we show a caliper being used to measure the length of an Object. The Object will be placed between the "jaws" of the caliper. The Object is almost exactly 75 mm (2.95 in) long. In the above photograph, you can see that on the top of the caliper are two "prongs" which can be used to measure an interior dimension. There is also a piece of metal sticking out from the right side of the caliper, which is a depth gauge. Calipers commonly use a vernier scale. In the simulation below, you may "grab" the jaw of the caliper with the left button of the mouse and move it to some position. When you click on the Show button the distance between the jaws will be shown. Note that there is a small difference between the simulation and a real caliper: in the simulation the distance between the jaws is always an even multiple of a tenth of a millimeter. It does not allow readings between these values, for which we would have to estimate the value. The Java applet to simulate the vernier caliper was written by Fu-Kwan Hwang, Department of Physics, National Taiwan Normal Univ., and is used by permission. See related link for the applet.
Their Vernier scale consists of two readings; the Vernier scale and the main scale. One can read that by the first line is the main scale and the next line is the Vernier reading.
the tool used to measure a area is a tape measure
Least Count [L.C]:-Least count is minimuim acuurate value meauserd by instrument.Least Count of Vernier Callipers:-The minimum value measured is 0.1mm but nowa days [l.c] is of 0.5mm.'
Because the secondary scale, which gave the calipers it accuracy, was designed by the French mathematician Pierre Vernier.
Vernier Calipers are instruments that are used measure length. It is an instrument that provides a digit of accuracy.
There are several conclusion for Vernier calipers. One is that in comparison to other tools like micrometers, they have less accuracy. Regardless, the Vernier calipers seem to allow a larger measurement range leading to better versatility.
Vernier calipers are used to measure length when quite accurate measurement is required, but not such accuracy as to require a micrometer.
The vernier calipers is used to measure length of small objects to an accuracy of 0.01 centimeters.
I guess it is found by vernier as it works on vernier theory -Manasa
Vernier Caliper are made with different materials even plastic vernier calipers are also available in market however generally stainless steel is used in making of vernier calipers

A caliper is a tool that can be used to measure both internal and external diameter accurately. It consists of two arms with measuring jaws that can be adjusted to fit the size of the object being measured. The different types of calipers include digital, dial, and Vernier calipers.
Vernier calipers are in use in machine shops throughout the world. Of course, they are gradually being replaced by digital calipers but, plenty are still in use in England.
Vernier calipers is more convenient to use compared to the external and internal calipers because vernier caliper by its own could be used as external and internal calipers. When using Vernier caliper you can identify the measurement withtout using ruler, meter stick etc. but the internal and external calipers rely on measuring tools to know the exact measurement...

The modern vernier caliper reads to thousandths of an inch
