Best calipers for 2020

A vernier caliper is an indispensable device for construction or minor repairs. Thanks to him, a person will be able to accurately determine the size or diameter of the product, as a result of which the risk of rejection is minimized. The editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best calipers for 2020.

Device: working principle

Each such device consists of 6 components:

• Measurement sponges;
• Fixing screw;
• A movable frame that allows you to move along the bar;
• Auxiliary scale (vernier) for accurate measurement;
• Measuring rod;
• Depth gauge.

Before carrying out work, it is important to check the current state of the caliper, if there is a deviation, adjustments should be made. In the case when the device has been used several times, and now it has skewed lips, it is not recommended to use it. Also, the device will not give accurate readings if it has nicks, and there are traces of corrosion or scratches on the working surfaces that interfere with accurate measurement. Therefore, before starting work, align the measuring jaws and make sure there is no gap. Clean the scale from dust and dirt, carry out test measurements.

The measurement takes place as follows:

• The jaws of the tool are pressed to the part to be measured, while it is important not to exert special efforts, and there should be no gaps and distortions;
• When measuring the outer diameter of a cylinder, it is important that the plane of the frame is perpendicular to the axis;
• To take measurements inside a cylindrical object, the device jaws are installed at the most distant points;
• To measure the depth of the product, a depth gauge is used, which extends using a movable frame.

When working with a caliper, it is important to consider the smoothness of the frame. The movement should be smooth and easy; the frame sits tightly on the bar, without swaying. Only then will a person receive the most accurate result. If, when aligning the jaws, the zero stroke of the auxiliary scale does not coincide with the bar, then loosen the screws at the vernier, align the zeros and fix them in the correct position.

Types of calipers

Depending on the type of scale used, the device is divided into: electronic and mechanical. However, this is a common division, and according to GOST 166-89, tools are:

• SHTs-1. A classic device that is found in almost all types of work. The error reaches 0.03 mm, it is used for external and internal measurements of products. The cost on the market varies: so cheap ones get for 400 rubles, expensive ones for 1500 rubles. In model ШЦ-2, the sponges are made of durable steel; any object from 0 to 250 mm can be measured. ШЦ-3 is intended for measuring the size of dimensional parts up to 500 mm. In this case, the length of the sponges reaches 30 cm.
• ShTsK. Unlike the previous model, the device has a dial, which allows a person to determine the exact size with a minimum error. Quality models are made of stainless steel. The movement of the auxiliary frame is carried out by a gear mechanism. In shops you can find tools with a maximum measuring range of up to 300 mm.Often used to measure parts in the factory or in the technical department. control.
• SCT. It is a standard device of the ShTs type, but made of harder materials, thanks to which the wear resistance increased. It is more often used by specialists for measuring pipes.
• SCC. The difference between this device and the rest is that this device has a digital indication. The result obtained can be immediately converted into inches or left in millimeters, which also affects the ease of use.

There are also models for measuring center-to-center distances, for brake discs, tread, etc.

How to choose a vernier caliper?

It is worth remembering that when buying a measuring device, a person does not acquire another tool, as it may seem to him, but invests in future work. After all, nothing affects the final result as the accuracy of measurements, so if the product is measured incorrectly, it can only bring losses and disappointment. It's one thing if a person works for himself and can easily replace a bad product with a good one. Another is if it is a large enterprise that can lose not only profit from the party, but also reputation and consumer confidence. Therefore, there should be no savings in such matters. A vernier caliper is not a tool for a one-time use, and the operation of a tuned and tested device will give a high result of work.

Since the Soviet period, the market for tools has expanded, not only the qualitative characteristics of the device have grown, but also the functionality has increased. Now vernier calipers are used in construction, in mechanical engineering, in the manufacture of products from plastic, steel, aluminum, etc. Each device differs both in the complexity of the application and in the accuracy of measurements.

One of the most popular types is ШЦ-1, aka Columbus. This tool has gained wide popularity in the market due to its functionality and affordable price.

Briefly about a caliper, we can say that this is a device whose main function is to measure external and internal dimensions with an accuracy of 0.001 mm, as well as depth.

To make it easier for a person to navigate in the choice of an instrument, you first need to decide what to measure and under what conditions. Having answered these questions, you can proceed to the next point.

The cost

When choosing a caliper, the first thing people pay attention to is the price, only then they look whether the product meets their demand or not. However, everything is not simple here, because a person can order a cheap device from Aliexpress for 200 rubles and find a similar one in a store for 1000 rubles. The difference will be in the accuracy of the measurement, therefore, when choosing a caliper, remember that the higher the cost, the more accurate the device. For 2020, there are devices with a graduation rate of 0.001 mm, and the error reaches a micrometer. More often these are electronic devices, for dials the graduation is 0.02, and for standard verniers it is 0.03. Therefore, if accuracy is the most important thing, then SCC is a suitable option.

In addition to accuracy, there is also a difference in length. Standard models reach 125 mm, and special ones, which are designed to perform complex technical operations - 5000 mm.

Also, some models have a number of additional advantages over their counterparts. For example, removable carbide tips may be supplied in the kit for extended service life. And other instruments are equipped with the control of the pressing force, which will allow a person to avoid an error in the measurement. Therefore, it is not worth saving on the purchase of an accurate device, otherwise the money will fly into the void, and the person will get more problems than solutions.

Design features

A caliper is that unique tool that amazed people with its simplicity and effectiveness. The first modern device was released at the end of the 18th century, and since then its main design has not undergone significant changes. The fixed bar is as it was and remains, the upper and lower jaws are still in their places, and the movable element performs its original function.

Some models have a depth gauge, others are for tire tread or for internal measurements only. Therefore, when choosing a tool, it is worth remembering the design features and additional functions that are rarely useful in everyday life.
