Infrared thermometers work very well when measuring the temperature of hot oil. For deep frying it's not a big deal, as standard probe thermometers work fine. But for shallow frying or sauteeing, the IR thermometer does an excellent job at providing the temperature of the oil.
Infrared thermography (IRT) , thermal imaging, and thermal video are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000â14,000 nanometers or 9â14 Âµm) and produce images of that radiation, called thermograms.
