How to choose a tire pressure gauge

Auto and Moto

Before starting to move, 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 car – the fuel rail, the turbine, it can be used to measure the compression of the car engine. There is a wide variety of devices of this class on the market, and everything that a user needs is the most appropriate one.

Top Manufacturers of Automotive Pressure Gauges

Preference should be given to high-quality devices from well-known manufacturers:

  1. Alca;

  2. Daewoo;

  3. Berkut;

  4. Pit-Stop;

  5. Rubber;

  6. KachoK;

Feedback on the functionality of the products of the above-described brands can be found in specialized automotive forums, as well as in those social media groups that are dedicated to automotive topics.

Types of pressure gauges

Dial gauge

Dial gauge

The most common type of such devices, the readings in which are displayed using an arrow with values ​​that moves around a special dial. The tribco-sector mechanism, paired with a spring-loaded diaphragm, measures the pressure and displays the obtained figures on the scale of the device.

Advantages

  • Compact;

  • Low price;

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

disadvantages

  • Critical to moisture;

  • The need to calculate the arithmetic mean to obtain specific numbers;

  • Mediocre measurement accuracy;

Rack pressure gauge

Rack pressure gauge

A very original design that provides a fairly high accuracy of measurements. Its appearance resembles a hollow compact tube, inside which there is a special rod with a marked scale. During measurements, it protrudes from the tube body as much as the pressure in a particular tire is high. Its distribution is small, mainly motorists use it.

Advantages

  • Small size;

  • Inexpensive;

  • High reliability;

disadvantages

  • Inconvenient to operate;

  • Mediocre measurement accuracy;

  • The design is very fragile;

Electronic pressure gauge

Electronic pressure gauge

A modern type of such devices, characterized by ease of operation and high measurement accuracy. The measuring sensor is housed in a compact housing, and the readings are displayed on an integrated liquid crystal display. The device is almost always powered by a small coin-cell battery

Advantages

  • Tiny size;

  • LCD display as indicator;

  • High measurement accuracy;

  • Miniature weight;

disadvantages

  • Requires regular battery replacement;

  • Are afraid of exposure to cold;

  • More expensive than analog devices;

The main criteria for choosing a pressure gauge

In addition to the type and functional differences of a particular pressure gauge, there are also key parameters to consider.

Measurement accuracy class

All devices on sale are divided into three main classes:

  1. First class – the error of the measurements performed ranges from one to 0.5;

  2. The second class measures values ​​with an error of 0.5 to 0.1;

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

The first and second classes traditionally include devices of switch and rack structures, in order to obtain acceptable measurement results, at least 3-4 measurements should be made and the arithmetic mean value should be calculated. Digital devices do not have such a feature – one measurement is enough to obtain acceptable accuracy;

Units

In order not to get confused in the results obtained, preference should be given to models that perform measurements in such units of measurement as Atmospheres, BARs, and kilograms per square centimeter. When it comes to electronic devices, many manufacturers provide the ability to switch units while measuring.
