The 3 main types of food thermometers are instant-read insertion probes, leave-in cooking thermometers and noncontact infrared instruments. Instant-read models spot-check the center; leave-in models track change during cooking; infrared models scan only a surface.

Common questions

Questions before you buy

What are the three main types of food thermometers?

A useful kitchen classification is instant-read probe, leave-in cooking and noncontact infrared. Each measures a different stage or location.

What is the difference between instant-read and leave-in thermometers?

An instant-read model is inserted briefly to check a spot. A leave-in probe is built to remain in food while its cable or wireless system reports the temperature.

Is a dial thermometer a separate type?

Dial describes the display. A dial model may be a bimetal instant-read or an oven-safe leave-in thermometer, so check its sensing area and instructions.

Which thermometer type works for thin food?

A fine, tip-sensitive thermocouple or thermistor probe is easiest to position in the center of a thin patty or cutlet from the side.
