What are infrared thermometers used for?

  1. Measuring internal temperature of food

  2. Used to surface temperature of food and equipment

  3. Monitoring room temperature

  4. Checking water temperature

The correct answer is: Used to surface temperature of food and equipment

Infrared thermometers are primarily used for measuring surface temperature. Option A is incorrect because infrared thermometers are not meant for measuring internal temperature. Option C is incorrect because infrared thermometers are used for measuring surface temperature, not room temperature. Option D is incorrect because infrared thermometers are not designed for checking water temperature. Infrared thermometers use a sensor that detects the thermal radiation emitted from a surface, giving an accurate measurement of surface temperature. This makes them useful for quickly and non-invasively measuring the temperature of food and equipment without the need for physical contact.
