What does a bimetallic stemmed thermometer measure?

A bimetallic stemmed thermometer is a type of temperature-measuring device designed for use in various food safety applications. It measures temperature within a broader range, specifically from 0 to 220 degrees Fahrenheit. This wide range allows it to accurately measure the temperatures of both hot and cold foods, which is essential to ensure proper cooking and serving temperatures to prevent foodborne illnesses. The bimetallic stem of the thermometer consists of two different metals that expand at different rates when heated, allowing for precise measurement of temperature.

Other options do not cover the necessary range for the applications required in food service. For instance, while options with lower maximum temperatures might be usable for certain culinary tasks, they would not suffice for all cooking processes, particularly those that require precise temperature checks for safety and quality in foodservice management. As a result, the ability to measure temperatures up to 220 degrees is a crucial feature of the bimetallic stemmed thermometer, making it an essential tool for food safety professionals.
