Although the temperature is important information in combustion research and development, it is very difficult to accurately measure the temperature of combustion gases. Thermocouples are inexpensive and traditional measuring tools but careless use leads one completely wrong result. In this lecture, tips for using thermocouples are introduced for beginners, and also several non-intrusive infrared emission methods including CT method for combustion gases are introduced and discussed for better application and accuracy.
