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.
- New: Unparalleled speed with full temperature readings in less than one second
- New: Industry leading accuracy to half a degree: ± 0.5°F (±0.3°C)
- New: Brighter intelligent backlight display automatically illuminates in low-light and when the sensor window is covered
- New: Easy access battery housing uses one common AAA battery for a 2,000-hour battery life
- New: Five-year warranty
- Motion-Sensing Sleep and Wake Mode: intuitively turns on and off—or when picked up or in use and off when set down to save battery
- Patented 360° auto-rotating display uses accelerometer technology to intuitively turn right-side up
- Shockproof, dustproof, and waterproof with an IP67 rating for water-tight seals
- Foldaway design protects probe when not in use
- Polygiene Biomaster Antimicrobial Silver Ion Technology reduces microbial growth
- Hand washable
- Display temperatures in °F or °C, 1° or 0.1° resolution
- Each Thermapen ONE includes a NIST-traceable calibration certificate verifying accuracy to national standards
The new Thermapen ONE includes professional level features at an affordable price, including an auto-rotating display, which uses accelerometer technology to detect screen motion/orientation for use in either hand (similar to smartphone orientation); a battery-saving sleep/wake mode; fully waterproof IP67 design; new brighter automatic backlight for use at night or in low light; 2,000-hour battery life using one AAA battery with new easy-access battery housing; and included NIST-traceable calibration certificate for increased confidence in its performance. Thermapen ONE lets everyone “seek perfection” when cooking at home, in the BBQ pit, or for daily use in professional restaurants, to measuring critical temperatures in labs, food processing plants, grocery stores, and more.
