What is a "thermocouple"?

A thermocouple is indeed a type of metal-probe thermometer. It is widely used in various cooking and food safety applications due to its ability to provide accurate temperature readings quickly. The device operates by measuring the voltage difference that arises at the junction of two different metals, which correlates to temperature changes. This allows chefs and food safety managers to check the internal temperatures of foods precisely, ensuring that they are cooked to safe levels or stored appropriately to prevent bacterial growth.

The design of a thermocouple permits it to be used in a variety of settings, including both solid and liquid foods, and it can often be found in kitchens due to its reliability and speed. Using a thermocouple is essential in food safety practices as it helps maintain compliance with health regulations regarding safe cooking and holding temperatures.
