Thermapen ONE Instant-Read Thermometer
Last verified by the Lifetime Picks Editorial Team
Why we picked it
1-second reading accurate to 0.5°F across full range
The Thermapen ONE is the kitchen thermometer professional cooks, BBQ competition pitmasters, and r/sousvide all converge on. 1-second reading, accurate to 0.5°F across the entire range, IP67 waterproof, auto-rotating display, motion-activated wake. Made in American Fork, Utah. Where cheaper thermometers drift after 2 years and need replacement, the Thermapen has a 5-year warranty and ThermoWorks honors calibration recertification indefinitely for a small fee. The thermistor itself is the same medical-grade sensor used in food-safety industrial applications, not the cheaper RTD elements in $20 thermometers. ATK's Equipment Review winner repeatedly across multiple years.
