How to choose a tire pressure gauge

Before you start driving, motorists are advised to check air pressure in each of the wheels of your iron horse. For those a pressure gauge is used – a special device that measures pump pressure not only in the wheels, but also in other nodes car – fuel rail, turbine, with it you can measure the compression of the car engine. Presented on the market a great variety of devices of this class, and all that it is necessary for the user – correctly the most suitable.

Top Automotive Pressure Gauge Manufacturers

Preference should be given to quality devices from famous 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 found in specialized automotive forums, as well as in those groups of social networks that are dedicated to automotive subject.

Types of Pressure Gauges

Dial gauge

Dial gauge

The most common type of such devices, readings in which are displayed using the arrow with the values moving around a special dial. Tribal sector a mechanism paired with a spring-loaded membrane measures pressure and displays the numbers 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 for obtaining specific numbers;

  • Mediocre accuracy of measurements;

Rack gauge

Rack gauge

Extremely original design, providing enough high accuracy of measurements. Its appearance resembles a compact hollow tube with a special a rod with a marked scale. When taking measurements, he extends from the body of the tube as high as the pressure in specific tire. Its distribution is small, enjoy in mostly motorists.

Advantages

  • Small dimensions;

  • Inexpensive

  • High reliability;

disadvantages

  • Inconvenient in operation;

  • Mediocre accuracy of measurements;

  • The design is very fragile;

Electronic pressure gauge

Electronic manometer

A simplicity of modern type of such devices operation and high accuracy of measurements. Measuring the sensor is enclosed in a compact housing, and the readings are displayed on integrated liquid crystal display. Source of work the device almost always comes out a small battery- “tablet”

Advantages

  • Tiny sizes;

  • LCD display as an indicator;

  • High accuracy of measurements;

  • Miniature weight;

disadvantages

  • Requires regular battery replacement;

  • Afraid of the effects of the 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, pay attention to key parameters.

Accuracy class of measurements

All devices on sale are divided into three main class:

  1. The first class – the error of the measurements varies in range 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. He produces tire pressure measurements with an error of less than 0.1;

The first and second classes traditionally include devices arrow and rack design, in order to get acceptable measurement results, should be performed, at least 3-4 measurements and calculate the arithmetic mean value. Digital devices lack such a feature – just one measurement is enough to get an acceptable accuracy;

Units

In order not to get confused in the results obtained, preference should be given to models performing measurements in such units of measure like Atmospheres, BARs and kilograms per square centimeter. When it comes to electronic devices, many manufacturers provide the ability to switch units directly to measurement lead time.
