Surface Thermometers for Cooking: How to Choose

It measures surface temperature, not the coldest internal point. Use a suitable penetration probe to assess internal doneness and safety.

Reflective, low-emissivity surfaces can produce misleading readings. Follow the instrument instructions and measure a suitable nonreflective target when possible.

It describes how the measured area grows as the thermometer moves farther from the target. Stand close enough that the spot fits entirely on the surface.

An infrared thermometer generally reads the glass surface rather than the object behind it. Measure the intended surface directly and follow the maker's safety guidance.
