You can use air gauges to measure different properties of air such as temperature and pressure. To measure pressure, you will require an air pressure gauge and to measure temperature, you will require an air temperature gauge. In addition to these types of air gauges, there are air fuel ratio gauges which measure the ratio of oxygen to fuel in a combustion engine.

Some important factors you must consider before buying an air gauge are:

1. Type of air gauges required
2. Measuring range of the air gauges
3. Desired accuracy
4. Type of display: analog or digital

The best contacts and resources to help you get it done

Shop for air pressure gauges from a reliable supplier

There are wide assortments of air pressure gauges available in the market. You can choose an air pressure gauge based on the above-mentioned factors.

I recommend: Technical Specialties Inc. features an array of industrial air gauges with different dial sizes. You can choose the display size, pressure range and connection hose diameter. At Northern Tool + Equipment, you can choose between an industrial and tire air gauge. You also have a choice between an analog and a digital air gauge. Omega.com is another source that provides a wide range of pressure gauges such as liquid filled gauges, low pressure gauges and differential pressure gauges.

Buy an air temperature gauge from a reliable gauge manufacturer

Air temperature gauges work in the same way as thermometers. For an air temperature gauge, it is important to consider the operating environment.

I recommend: A wide range of gauges for air temperature as well as pressure measurement is available at Palmer Wahl Instrumentation Group. In addition, you will find an extensive range of temperature gauges at Mid States including precision service gauges and special application gauges. Cyberdyne Gauges is another manufacturer that provides digital air temperature gauges. The company also provides other air electronic gauges including air pressure gauges and air fuel ratio gauges.

Shop for air fuel ratio gauges

An air fuel ratio gauge, also called an air-fuel meter, is a key instrument in identifying the problems associated with non-optimum air-to-fuel ratio that may lead to inefficient fuel usage in a vehicle.

I recommend: Innovate Motorsports offers a range of air fuel gauges through a wide network of dealers in the US. At AllCarGauges, you can buy a standard air fuel gauge or a more accurate wideband air fuel gauge. You can also choose a digital or an analog display as per your requirements.
