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.
With full readings in ONE second or less, Thermapen ONE approaches the speed of thought - allowing you to focus exclusively on the quality of your work. Achieve such speed and accuracy without sacrificing durability and usability.
ONE. Second. Readings.
Thermapen ONE almost moves at the speed of thought...allowing you to focus exclusively on the quality of your work.
The newly designed rugged, waterproof case features a 5-year warranty against defects.
With an improved accuracy spec of ± 0.5°F (± 0.3°C), you’ll know your lightning fast Thermapen ONE readings are always accurate, as well.
The automatic backlight is brighter and the light sensor is more sensitive to changes in ambient lighting conditions.
With a newly designed battery compartment for easier access to the user settings and all the amazing features you loved in the Thermapen Mk4—auto-rotating display, motion-sensing sleep and wake mode, waterproof to IP67, NIST-traceable calibration certificate—you'll need to get ONE for yourself to understand the power of sub-second performance.

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
- 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.

Let customers speak for us20 reviews
Like always,there is something last minute and in my case needed to take something to Germany, for my cousin. Looks impossible, feels impossible because of time constraints but this is where good customer service shines bright and they certainly do. Friendly, helpful and competent, rare combination now days but here certainly available. Thank you again for a great job, well done.
I bought this product early 2022 and it was shipped promptly and received in good condition. January 2023 I get this email asking for a review, as the title says great product weird customer support.
It was a gift. Don’t know if they used it yet
I was 3 months ago
Great products & shipped immediately
