Buying advice: meat thermometers
- 1Instant-read suits steaks — chicken and spot checks. Leave-in probes suit roasts and smoking. Wireless probes suit grilling while you're away from the cooker.
- 2Good instant-read thermometers settle in about 1 to 3 seconds. Slower models need longer in the meat.
- 3Look for accuracy with in about ±1°F. Test in ice water (32°F) and recalibrate if your model allows.
- 4A th in probe tip leaves smaller holes. A backlit, auto-rotating display helps at night and for left-handed cooks.
- 5Bluetooth range drops through walls and grill lids. Wi-Fi models avoid range limits but need setup.
