This tool for measuring magnitudes, known as a vernier caliper, is also known as a vernier and caliper. The name “vernier” is given thanks to the French mathematician Pierre Vernier, inventor of the caliper and of the vernier scale, a scale that is applied in measurements in conjunction with the caliper.

The function of the vernier scale is found in the vernier, a complementary scale that works by increasing the accuracy of measurements taken by the caliper. By using a measurement tool, such as the ruler, you can detail that there are divisions between its divisions, divisions that are not marked, including among the smallest.

The vernier fulfills the purpose of marking those tiny divided spaces, thus giving you visibility to accurately check the measurements taken. Today there are several types of vernier, used in different work areas, it is widely used in constructions, especially in measurements that require precise measurements.

Once we have defined what a vernier scale is, we can proceed with the vernier scale.

What is the vernier caliper?

The caliper is a masterful instrument, its specialty is precise measurements, there is no millimeter that escapes this tool, it is the tool with the greatest accuracy in its measurements today, surpassing many other measurement tools. The caliper is made up of a base that fulfills the role of a rule, at the ends it has pieces to measure internal and external areas, including a vernier.

With the ruler, two types of measurements are made, the low point of the instrument is used to measure millimeters, the high part to measure inches. Similarly, at the upper end of the instrument there is a holder for internal and external measurements, corresponding to the large clamps for external measurements and the small clamps for internal measurements. On the other hand, the lower part consists of a rod to measure the depth.

We can say that the caliper is a comprehensive measuring instrument, from its impeccable utility to measure accurately, to the multiple measurement tools that comprise it, tools that allow the user to measure a variety of surfaces. The vernier caliper has a functionality where you can move the vernier between the measures of the ruler and adjust the clamps in the right place to measure.

Parts of the vernier caliper

How many pieces you bring depends on the type of caliper that we mention, also, its characteristics vary; We will talk about the universal vernier caliper, since these are the fundamental pieces of all types of vernier calipers, with the exception of the digital one, since this, being automatic, does not need verniers. Every vernier caliper consists of 6 essential pieces.

  1. Body: It is the rule that joins the other pieces.
  2. Nonio: It is a small scrollable scale that divides the rule. The vernier caliper is made up of two verniers, one allows you to measure inches and the other for fractions of millimeters.
  3. Internal measure clamps: They are smaller than external measure clamps. It is made up of clamps, one that moves and the other is fixed.
  4. External measuring clamps: Like the internal clamps, it consists of two clamps, one fixed and the other that slides sideways to measure objects.
  5. Push button: It is the button that allows to fix the clamps after taking the measurement.
  6. Depth grid: It is located at the lower end, with it the depth is measured.

What does it perform?

He is the precise instrument to measure, clearly, there are other kinds of measuring devices and many rulers, such as the tape measure that gives us the facility to measure curved spaces. That said, what makes the vernier caliper special? The vernier caliper outperforms any measurement tool when it comes to recording exact measurements.

The importance of the vernier is obtained thanks to the multiple functions it possesses, coupled with this, the integration of the vernier. The vernier is located in a fragment and creates a subdivision in it, thus forming a segmentation between the first partition of the vernier and the first partition of the rule, separating the branch of the unit from the rule.

In this way, the highest accuracy in millimeter measurements is obtained. Without these fractionations between millimeters, the calculations would not make sense. Without that precision when measuring, you would have a high probability of recording inaccurate data. The caliper can be classified as the integral tool, since it has an ability to measure both internal and external areas, with tweezers that adjust to the environment.

Where can I use the vernier caliper?

It is normally used in construction, mechanical and lathe work. Its ability to measure both external and internal angles. It is the perfect tool for working on parts like nuts. It is the instrument commonly used in this type of work, despite this, that does not take away its usefulness in other disciplines, you can use it for other jobs, you just have to be careful when using it.

Using the vernier caliper is not difficult, but if you want to get the most out of its measuring capacity, we recommend that you learn to use it well; If not, what is the point of using a precision tool if the measurements will turn out to be inaccurate?

How to use it

  • The first step is to check that the instrument is straight level in the space to be measured.
  • Adjust the lower or upper calipers, it all depends on whether you want to measure the internal or external area of ​​the body.
  • Each pair of clamps has the ability to move.
  • Once the caliper is slid, you position it with the impeller so that it does not move while you are measuring the area.
  • Then, you continue to measure, check that the division of the ruler coincides with the “0” of the vernier.
  • You can measure the millimeters and check the correspondence of the principal with the vernier.

Keep in mind that measurements taken in inches require a different process, taking into account the decimal numbers in fraction. When using the vernier caliper you must be very careful, it is a very delicate tool. Whenever you finish using it, you should fix the impeller and close the clamps so they don’t roll through the ruler.

It is the tool known to every good mechanic, the use of this instrument covers any work space in which exact measurements need to be taken. Especially in hollow objects and pieces, in these cases both clamps are used, in addition to that, the depth gauge; the perfect tool.

How to read measurements

Once the measurements are taken by the vernier caliper, we will proceed to read it. To complete this procedure we have three different scales. The main scale with the fraction in centimeters (cm) and millimeters (mm), the scale that measures in inches, this scale is useful most of all when you are going to measure inches or a vernier of millimeters.

To make it easier we give you an example.

From the main scale you can see that it is about 31mm. The next step to follow will be to validate what the tenth of a millimeter is (the vernier will provide us with the result). On the vernier you will see a scale from 0 to 10. Find the line that matches the one of the lines on the first scale. In case you can’t find it, they match the third line of the vernier.

Once done, the result will be 3/10 a tenth of a millimeter. Giving as a final result an exact 31.3 millimeters

Caliper classes

As a result of the extensive range of pieces and objects that exist today, the vernier measurement system has opened up a world of possibilities to use different calipers in many ways, of different sizes, different measurements and functionalities. Some more difficult to use, others with a more accurate measurement capacity. Among them, we can name you a few.

 Digital vernier caliper

This tool stands out in precision as one of the highest among the feet of kings, thanks to the fact that it does not depend on any stimulus from man to obtain precise measurements.

Double caliper

This vernier caliper is the largest, as the name implies. It is the most used to measure gears.

Fine adjustment caliper (type M)

It is mainly used to measure small internal surfaces.

Caliper with adjustable caliper

It is the tool used to measure bodies with uneven or uneven ends, you can adjust the calipers vertically between the ends.

Kafer vernier caliper

To measure the thickness of materials, you can find them digital and analog.

Among the classes of calipers you will find that each of them specialize in a specific function, different sizes and the measurement ranges they have. Whenever you go to buy or get one, it is necessary that you analyze which is the one that best suits what you need to measure, thus you evaluate its characteristics of the type of caliper that adapts to the need that arises. However, if you feel unsure of which is the best option, you can opt for the universal one, it is the most complete.

What makes the caliper important?

When making measurements, the vernier caliper is the most needed instrument. This is thanks to its impeccable precision, measuring with this tool absolves us from registering erroneous results. With the arrival of the verniers, many of the mechanics’ headaches were alleviated, the verniers allowed measurements with a negligible margin of error, opening doors to other areas of work.
