The picks
Thermapen ONE
One-second readings, ±0.5°F accuracy
Thermapen ONE delivers full readings in one second or less. The one-second reading lets a cook check doneness without stalling. Accuracy is ±0.5°F, with a NIST-traceable calibration certificate. The probe rotates 180° and the display auto-rotates 360°, keeping readings clear in any hand or position. The housing is IP67-rated for splashes, humidity, quick rinses, and everyday cooking. A single AAA battery powers it for up to 2,000 hours of typical use. It comes with a 5-year warranty.
