Infrared thermometers are quick and effective non contact diagnostic tools for the automotive garage. Easy to use non contact handheld infrared thermometers make it easy and safe to identify engine misfires, cooling system problems, make sure the air conditioner is working correctly, check exhaust temperature and a whole lot more.  In this article, we will give a brief summary of the some automotive applications for these tools.

1. Infrared thermometers enable a mechanic to take quick and safe measurements and diagnose temperature related issues for the engine and exhaust systems.  You can measure both sides of the catalytic converter for variations in the temperature. Also, you can easily measure the manifold temperature to detect if a misfire is possible or to determine low compression. Just simply pointing and pulling the trigger at  a distance of 2 feet, the temperature can be safely and accurately measured.
2. The cooling system is another big area for infrared thermometers. The IR thermometer can check radiators for excessive heat, measure temperature on the thermostat, and measure coolant temperature sensor.
3. The air conditioning system is probably one of the more obvious places to use an IR thermometer. A A/C technician can easily check if the heater, air conditioner and vents are cooling and heating to the proper temperature. Just aim it at the A/C vent and presto you tell exactly how cold the air blowing from the vent is.
4. The brake system is also a great place to use this tool. An infrared thermometer can tell a brake mechanic if there is uneven heat among the brake rotors. If one brake rotor is significantly higher than the rest could indicate a serious problem or excessive wear.

There are a lot of applications in the modern automotive shop or for the garage mechanic with an portable infrared thermometer. Once, you use you will wonder how you ever got along without it.
