Final answer:

A type K thermocouple probe should be used to check the internal temperature of a beef roast. Thermocouple probes are temperature sensors that measure temperature based on the voltage produced when two different metals are heated. Type K thermocouples are suitable for measuring high temperatures and are commonly used in the food industry.

Step-by-step explanation:

To check the internal temperature of a beef roast, a thermocouple probe should be used. A thermocouple probe is a type of temperature sensor that consists of two different metals joined together to create an electrical junction. When the junction is heated, it produces a voltage that can be measured and used to determine the temperature.

In the case of a beef roast, a type K thermocouple probe would be suitable. Type K thermocouples are made of chromel and alumel and can measure temperatures up to around 1,372 degrees Celsius (2,502 degrees Fahrenheit), which is sufficient for checking the internal temperature of a roast. They are also durable and commonly used in food industry applications.

To use a thermocouple probe, simply insert the probe into the thickest part of the beef roast, avoiding any bones. Allow a few seconds for the temperature reading to stabilize, and then read the temperature from the thermocouple display or connected measuring device.
