What are infrared thermometers used for?

  1. Measuring internal food temperature

  2. Checking the freezer temperature

  3. Measuring the surface temperature of food and equipment

  4. Monitoring oven temperatures

The correct answer is: Measuring the surface temperature of food and equipment

Infrared thermometers are used for measuring the surface temperature of food and equipment. Unlike probe thermometers which are used for measuring internal food temperature, infrared thermometers provide instant readings of the surface temperature without making contact. This makes them useful for quickly and safely checking temperatures of various surfaces without the risk of cross-contamination. While checking freezer temperatures and monitoring oven temperatures are important tasks in food safety, these activities are typically done using other types of thermometers designed for those specific purposes.
