Social Bookmarks

Handheld Infrared thermometers are great for all sorts of automotive and non-automotive applications. These little devices are easy to use and very handy. The first time I came across one, I thought they were just a neat gadget and nothing more. Then I used one. You will quickly discover tons of applications for them. It is easy to get an accurate measurement of temperature in difficult or hazardous places. For one thing, infrared thermometers are used everyday for automotive troubleshooting and diagnostics.  Quick infrared temperature measurements make it easy to identify engine misfires, spot cooling system faults, check for proper A/C performance, verify catalytic converter operation and much more. The temperature range is generally around cold -76° F to a blistering +1000° F (-60° C to 538° C). This is more than adequate for most automotive applications. Some units come with a jack for an eternal thermocouple that will read from -83° F to +2500° F.

In auto air conditioning service they are absolutely necessary. An infrared thermometer can check the output temperature on the heat and cooling. No more guessing about how cold the air coming out of the vent really is. This tool will give you a quick and accurate measurement. You also measure the temperature on a car's radiator temp and make sure it is with in norms and not excessively hot. The list goes on and on. Basically, anything on a modern automobile is a target for this handy device.

Infrared thermometers are mistakenly referred to as "laser" thermometers. They do not use a laser to measure the temperature. The laser is a sighting device that enables the mechanic to aim it accurately and make sure he is measuring the correct component or area. The laser sighting system is an option on most brands, but I highly recommend it. (The Reytek Auto Pro Infrared Thermometer is a good example.)
