Before you buy
- Put the tip in the thickest part, away from bone and fat. A probe reads one spot, so check a whole bird in a second place before serving.
- An infrared (surface) thermometer reads only the outside of food. It cannot tell you whether meat is cooked through.
- Whatever you buy, test it: in a glass of ice and water, stirred and left for 30 seconds, it should read 0 °C (32 °F).
- Safe temperatures do not change with the tool: poultry, including minced poultry, 74 °C (165 °F); whole cuts of beef, pork and lamb 63 °C (145 °F) with a 3-minute rest; minced (ground) beef, pork and lamb 71 °C (160 °F).
The three types, in short
Instant-read digital thermometer
You check food near the end of cooking, then take the thermometer out. One tool covers steaks, chops, chicken pieces, burgers and reheated leftovers (reheat those to 74 °C / 165 °F).
It cannot: It is not made to stay in the oven or on the grill while the food cooks.
Leave-in probe thermometer with a cable and alarm
The probe stays in the meat and a cable runs to a display outside the oven. You set a target temperature and it beeps, so the door stays shut.
It cannot: It is slow for quick spot checks, and the cable gets in the way when you turn food often.
Wireless leave-in probe
The probe stays in the meat with no cable and sends the temperature to your phone or a base. It suits long cooks you walk away from, a rotisserie, or a closed grill.
It cannot: It usually costs the most of the three, the signal can drop through thick metal, and thin cuts may be too small for the probe.
