Infrared thermometers are today the best alternative to the traditional thermometer for gauging temperature in a non - contact manner. They are used in almost every industrial sector that requires measuring temperature in their operations such as in gourmet industry, in household appliances, in electrical appliances, and the automotive industry among many others. In this article you would find information regarding their uses in the automotive sector. As mentioned above, infrared thermometers are used extensively in the automotive industry to diagnose problems ranging from air conditioning, brakes, to engines. They also help in avoiding dangerous car interiors by convenient temperature measurement with these non-contact devices. They are however most effective in diagnosing temperature-related engine problems. This is because, as with other traditional thermometers, the user doesn't have to dissemble the whole engine, as it reaches even inaccessible areas. Among the various uses of these infrared thermometers in engine and exhaust troubleshooting are for scanning manifold temperature to determine low compression, for misfire condition, measuring and comparing exhaust system components for correct fuel/air mixture and for scanning both sides of the catalytic converter for temperature differences. These are also used for cooling system diagnostics like checking for overheating problems, scanning radiators for core restrictions, measuring thermostat temperature and above all for measuring coolant temperature sensors and manifold air temperature sensors. Even for measuring climate control, in automobiles infrared thermometers are used most of the times. With them you can check heaters, air conditioners, and vents at a convenient pace for any kind of malfunction or system output. These are equally powerful like digital multimeters, as gauging instruments. Further, infrared thermometers are used for checking the condition of braking system in automobiles. This is very necessary because if the temperature is significantly higher than ambient or varied temperatures of rotors, drums or bearings, it would indicate excessive wear. Uneven braking can also be diagnosed with this amazing instrument. Use infrared thermometers, digital multimeters and digital pressure gauge for simple, fast and frequent temperature gauging and enjoy the difference.
