Which thermometer is used to measure the heat of sugar or hot oil?

• A. Meat Thermometer
• B. Infrared Thermometer
• C. Candy Thermometer
• D. Dial Thermometer

Answer: (C)

Measuring high-temperature liquids like sugar syrups and frying oil requires a thermometer designed to handle that heat and be read accurately while immersed. A candy thermometer has a long, heat-resistant probe that stays in the pot, with a scale that covers the very high temperatures needed for sugar work and for frying. This lets you monitor precise stages in candy making—where exact temperatures determine texture—and maintain the right oil temperature for even frying. Infrared thermometers read surface temps and can be thrown off by steam or the pot’s reflections, and they can’t reliably measure the temperature inside a liquid or hot oil. Meat thermometers target internal doneness in meat and aren’t designed for the high ranges or immersion in liquids, while dial thermometers may not reach the needed range or respond quickly enough for candy work. So, the candy thermometer is the best fit for measuring the heat of sugar or hot oil.
