There are many tools used in the automotive industry to help design, assemble and test cars. Measuring tools are used throughout all processes, from the design state up to final tests and troubleshooting. Automotive measuring tools are used to measure the length, width, depth and temperature of parts, and the distance between parts.
Calipers and micrometers are used to measure the physical dimensions of certain parts. Micrometers are used to measure important small parts that need to have their dimensions precise to the millimeter. The most common type of calipers used in the automotive industry is the Fowler Caliper, which is very similar to a Vernier Caliper, and can be used to measure the inner and outer diameter of pipes and hoses.
Multimeters are used both in production and in car troubleshooting, to make sure that the amperage and power of the electrical system is correct and to detect short circuits. A multimeter can measure amperage, voltage and electrical resistance. Multimeters may also be equipped with digital thermometers and magnetic backs, so they can be affixed to the body or chassis of a car to allow you to use your hands for other tasks.
An automotive thermometer is used to detect if the engine is overheating. They are usually infrared thermometers, and have pinpoint accuracy. They are also used to detect air conditioning system leaks, and are able to detect both overheated and over-cooled regions.
Auto testers can vary from simple handheld tools to complex car stands that will measure various parameters of your car, such as engine power or smoke emission. Handheld testers are generally used to measure fuel pressure, tire pressure and the charge level of the car battery. These tools can usually be found at a service station.
