This is really a "must have" instrument for pan frying, deep frying and even stir frying. Know instantly and accurately what your oil temperature is for precision control.
The unit in the photo to the left is by Electronic Specialties and available through the Internet at about US $41. It features a bright laser beam for precision aiming and measures surface temperatures from -22°F to 500°F/260°C. With a response time of less than 1 second, it's really great for measuring hot oil and other materials that are rapidly changing temperature - and you can measure from a safe distance.You'll find this type of thermometer absolutely useless for measuring refrigerator and freezer temperatures. The reason is that the moment room air contacts a cold object, water vapor starts to condense on it. Since condensing water is the actual surface, and this device measures surface temperature, you get odd results. For instance, I chilled a heavy piece of metal down to -4°F. Brought out of the freezer it measured not much below 32°F, the freezing point of the water that was frosting onto it.
This photo shows a very low cost unit available through the Internet for around US $19.99. It also features a laser beam for precision aiming and goes up to 482°F/250°C, which is sufficient for normal frying applications. Photo © source..
