How to choose a tire pressure gauge

Before you start driving, motorists are advised to check the air pressure in each of the wheels of your iron horse. For these purposes, a pressure gauge is used - a special device that measures the injected pressure not only in the wheels, but also in other parts of the vehicle - the fuel rail, the turbine, it can be used to measure the compression ratio of an auto engine. There is a great variety of devices of this class on the market, and everything the user needs is the right one.

The best car gauge manufacturers

Preference should be given to quality devices from reputable manufacturers:

1. Alca;

2. Daewoo;

3. Berkut;

4. Pit-Stop;

5. Rubber;

6. Kachok;

Reviews on the functionality of the products of the above brands can be found on specialized automotive forums, as well as in those groups of social networks that are devoted to automotive topics.

Types of manometers

Dial gauge

The most common type of such devices, the readings in which are displayed with the help of an arrow with values ​​moving around a special dial. The mushroom-sector mechanism, working in tandem with a spring-loaded diaphragm, measures pressure and displays the figures obtained on the scale of the device.

Virtues

• Compact;

• Low price;

• Do not require special skills when working with the device;

disadvantages

• Critical to moisture;

• The need to calculate the arithmetic average for obtaining specific numbers;

• Mediocre accuracy of measurement;

Rack gauge

A very original design that provides a fairly high accuracy of measurement. Its appearance resembles a hollow compact tube, inside of which there is a special rod with a marked scale. When performing measurements, it extends from the body of the tube as much as the pressure in a particular tire is high. Its distribution is small, mostly used by motorists.

Virtues

• Small dimensions;

• Inexpensive;

• High reliability;

disadvantages

• Inconvenient in operation;

• Mediocre accuracy of measurement;

• The design is very fragile;

Electronic manometer

Modern type of similar devices, characterized by ease of operation and high accuracy of measurement. The measuring sensor is enclosed in a compact case, and the readings are displayed on an integrated liquid crystal display. The source of the device almost always serves a small battery- "tablet"

Virtues

• Tiny sizes;

• LCD display as an indicator;

• High measurement accuracy;

• Tiny weight;

disadvantages

• Requires regular battery replacement;

• They are afraid of exposure to cold;

• More expensive analog devices;

The main criteria for selecting a pressure gauge

In addition to the type and functional differences of a specific pressure gauge, attention should be paid to key parameters.

Accuracy class of measurements

All devices on sale are divided into three main classes:

1. The first class - the error of the performed measurements ranges from one to 0.5;

2. The second class measures values ​​with an accuracy from 0.5 to 0.1;

3. The third class is the most accurate instruments. It measures tire pressure with an accuracy of less than 0.1;

The first and second classes traditionally include devices of the switch and rail construction, in order to obtain acceptable measurement results, at least 3-4 measurements should be taken and the arithmetic average should be calculated. Digital devices of this feature are devoid of - one measurement is enough in order to obtain acceptable accuracy;

Units

In order not to get lost in the results, preference should be given to models that measure in such units as Atmospheres, BARs and kilograms per square centimeter. When it comes to electronic devices, many manufacturers provide the ability to switch units directly during the measurement.
