Electronic vernier caliper from China for super accurate measurements

At the dacha there are always many things to do for repair or construction. Of course, the master should always have a tape measure at hand, as well as a ruler. Yet there are such planes that cannot be measured with such devices. In this case, an electronic vernier caliper from China rushes to the worker's aid. Thanks to the device, the diameter of any pipe or the depth of a non-standard hole is determined with extreme accuracy.

The nature of the universal tool

It is equipped with an LCD display. The result is displayed on it with an accuracy of 0.1 mm. Especially such measurements are needed when working with miniature or too thin structures. The nature of the caliper is determined by the following indicators:

1. Reading speed. Is 1.5 m / s. The master does not even have time to blink an eye, as the data will already be on the screen. As a result, in a few minutes he will be able to process dozens of parts.
2. Sharp image. If it has an unclear outline, then the electronics are defective or the battery needs to be replaced.
3. Large measuring range, which varies from 0 to 150 mm.
4. Upper and lower jaws. Must have a flat surface. When they are fully compressed, no gaps are formed. Due to their shape, they are able to penetrate any hole.
5. Zeroing. Set to zero regardless of position.
6. Power consumption. The device operates on one battery (1.55 V). Because of this, you have to periodically change the battery.

In all vernier calipers, an error of 10% is allowed both in the direction of decreasing and increasing. In the industrial sphere, such devices undergo metrological control every 6 months.

In the upper part of the display there is a button for switching units of measurement: from millimeters to inches, and in the lower part - on / off the device. The reset key is located in the same row. Of course, at first glance, it may seem fragile, since it is made of plastic. However, this is precisely its advantage. It is comfortable to hold the instrument in your hand, because it is not too heavy and at the same time not cold.

What does the client need to know?

It is important to understand that electronic calipers go out of tune due to the impact of sudden changes in temperature and humidity. Moreover, it is susceptible to mechanical damage, which is often considered the cause of breakdown. Therefore, it is necessary to work with such accurate instruments very carefully.

Many people hesitate to purchase the electronic version of the caliper, because it is too expensive. Nevertheless, on the Aliexpress site, the price for measuring goods of this class is 463 rubles. But metal ones or with a dial are several times more expensive - from 1,500 rubles. in regular stores.
