Which thermometer can measure food temperature up to 220°F?

The bi-metallic stem thermometer is designed to accurately measure the temperature of food and can handle temperatures up to 220°F. This type of thermometer consists of a metal probe with a sensing element that expands or contracts as the temperature changes. When inserted into food, the probe provides a reading based on the temperature at the core of the food item, making it suitable for various cooking applications and ensuring food safety.

It's important to understand that other thermometer types have different ranges and applications. For instance, thermocouples and thermistors can measure temperatures over a wide range but may not be as commonly used for direct food temperature measurements as the bi-metallic stem thermometer. Infrared thermometers are great for measuring surface temperatures but do not measure internal temperatures accurately, which is crucial in ensuring food is cooked safely. Thus, for monitoring food temperatures specifically up to 220°F, the bi-metallic stem thermometer is the appropriate choice.
