3x Faster Readings
Thermapen ONE is engineered for speed, delivering precise temperature checks in just one second — so you can focus on cooking.
More Accurate
With an improved accuracy spec of ± 0.5°F (± 0.3°C), Thermapen ONE ensures you’re getting even more reliable readings for perfect results.
Brighter Backlight
Thermapen ONE’s upgraded automatic backlight is brighter, with a more responsive sensor that adapts seamlessly to any ambient lighting.
2.5x Longer Warranty
Built with a newly designed, rugged, and waterproof case, Thermapen ONE now comes with a 5-year warranty against defects — offering extra peace of mind.
Enhanced Usability
Thermapen ONE features a newly designed battery compartment to easily switch out the AAA and access user settings like scale (°F or °C) and sleep-wake mode.
Thermapen MK4 set the bar for speed and accuracy, but Thermapen ONE raised it further. Delivering full readings in just one second, it’s nearly three times faster than the MK4, capturing temperatures instantly so you can keep your focus on cooking. With improved precision and enhanced durability, Thermapen ONE is built to perform and last even longer.

With full readings in just one second, Thermapen ONE is in a category by itself when it comes to “instant-read” thermometers. Thermapen ONE achieves a new standard of accuracy, as well—now accurate to ±0.5°F (±0.3°C)—so you know your readings are correct. To achieve this level of performance without resorting to algorithms or mathematical adjustments, Thermapen ONE truly pushes the boundaries of sensor and electronic measurement engineering.
