Infrared thermometers are designed to measure the surface temperature of objects without making direct contact. This is achieved by detecting the infrared radiation emitted by the surface, which allows the thermometer to calculate the temperature efficiently. This feature makes infrared thermometers particularly useful for quickly measuring the surface temperatures of food items, equipment, and surfaces in various environments, which is vital for maintaining food safety and ensuring proper cooking and storage temperatures.

In contrast, measuring internal temperatures typically requires a probe thermometer that can reach the core of the food item. Ambient temperature refers to the general temperature of the surrounding environment and is measured using other types of thermometers. Core temperature specifically concerns the innermost part of a food item, which is essential for ensuring that food is cooked thoroughly and safely. Therefore, the infrared thermometer’s function is specifically tied to assessing surface temperatures, making it an important tool in food safety practices.
