Thermapen® NANO

Thermapen NANO is designed to outperform Thermapen ONE, improving on several key features: Speed: Thermapen NANO reads in an ultra-fast 0.4 seconds, compared to the Thermapen ONE's previous industry-leading 1 second. Storage: Thermapen NANO includes a highly requested built-in magnet. Visibility: The Thermapen NANO display is 300% brighter, making it easier to read during evening barbecues or in low-light conditions. Design: The overall body of Thermapen NANO is thinner. Usability: Thermapen NANO features an easily accessible °C/°F toggle button directly on the back.

Yes. The Thermapen NANO is the definitive successor to the Thermapen ONE. It introduces new and innovative technology that leverages decades of engineering insights to push the limits of what’s possible while setting a new standard for speed.

Yes! Unlike previous models, Themapen NANO features two built-in magnets. This allows you to effortlessly stick it to suitable magnetic surfaces—like your grill, oven, or refrigerator—so it is always within reach.

Yes, Thermapen NANO is fully waterproof with an IP67 rating. This means it can easily survive heavy splashes, messy kitchens, and even brief drops into the sink.

Thermapen has streamlined the settings process. Instead of needing to open the battery compartment, Thermapen NANO features a much more accessible °C/°F switchable button located directly on the back of the device.

The NANO was officially unveiled August 2026, and all pre-order shipments are scheduled to begin shipping out in October.

Thermapen NANO offers professional-grade precision with an accuracy guarantee of ±0.3°C. Unlike cheap mass-produced thermometers, every single Thermapen NANO comes with a NIST-traceable calibration certificate, proving it was individually tested before shipping to ensure spot-on results.

ThermaBoost is the patent-pending technology engineered into Thermapen NANO that allows it to achieve its unprecedented 0.4-second reading time. Our patent-pending innovation intelligently accelerates the sample rate to 20x per second during temperature shifts. You get actual real-time data with zero guessing.

Value corresponds directly to investment; you truly get what you pay for. While the lifespan of many imitation houseware products is often measured in months or even weeks, Thermapens are professional instruments, handcrafted in the UK and built to last. Thermapens have a well-documented history of lasting 10 years or more—and many units from 20 and even 30 years ago are still operating today. Thermapens continue to prove that investing in the best instruments pays off. Rather than buying multiple items multiple times, remember that quality isn't expensive; it's priceless.

Absolutely. Its IP67 waterproof rating protects it against the heavy spills and constant washing of a commercial environment. Because it is handmade in the UK specifically to withstand professional wear and tear—and comes backed by a 5-year guarantee—it is highly reliable for high-volume, demanding kitchens.

Nothing has changed with your Thermapen ONE warranty. Thermapen NANO is backed by the same 5-year warranty and is supported by our US-based support team here in American Fork, Utah.

Yes, and we were able to improve that accuracy over a wider range, making more readings more accurate with Thermapen NANO.

Yes. The power needed to deliver this kind of improved speed, brightness, and accuracy means that NANO has its own unique battery life specification. We introduced our patent-pending ThermoBoost technology in Thermapen NANO to optimize that performance and battery life. Even with faster speeds and a brighter backlight, you’ll still have about 1000 hours of battery life with Thermapen NANO, so you can keep the extra batteries in the drawer for a long, long time.

Yes, the display is 4x brighter than Thermapen ONE with new design features that make it even easier to read from more angles and under more diverse viewing conditions.

Yes! Thermapen ONE was the industry standard until the first Thermapen NANO came off the line. NANO is 2.5x faster, 4x brighter, and 10% thinner than Thermapen ONE. It’s also jam-packed with all the latest technology and upgrades. At this remarkable introductory price, the NANO is a strategic addition to any culinary arsenal. We recommend transitioning your Thermapen ONE to a second cooking station or gifting it to an upcoming enthusiast while you adopt the new standard, Thermapen NANO. If you demand the best, Thermapen NANO is for you.

There are too many to only focus on one. Thermapen NANO is now 2.5x faster, 4x brighter, and 10% thinner than Thermapen ONE. It’s jam-packed with all the latest technology and upgrades. When you want the best, the fastest, and the most accurate thermometer, you only have one serious choice–Thermapen NANO!

Its unprecedented speed is the reason; it delivers readings 2.5 times faster than the current industry standard, the Thermapen ONE. In fact, most everyday cooks lack a stopwatch—or the lightning-fast reflexes—required to measure it accurately!

Yes. As soon as NANO came off the line, it became the world’s best candy, baking, and cooking thermometer. Order yours today and put it to the test.

As recipes continue to evolve in origin and complexity, being able to toggle between temperature scales on the fly has become more and more important. The location and design of the new button on Thermapen NANO help it disappear into your hand and out of your consciousness. Now you can focus even more on your craft while spending less time adjusting your instrument to shifting temperature scales. It’s one more way Thermapen NANO delivers unmatched speed.

The Thermapen NANO provides an actual measurement. Many competitors use "ramp-up electronics" to guess the final temperature based on a predictive algorithm. The NANO rejects this approach. By utilizing a high-performance Type K Thermocouple and 20x/sec polling, it captures the real temperature in 0.38 seconds. It does not guess; it captures the actual thermal curve. The sophistication of this internal architecture is matched by an external design that emphasizes both visibility and long-term durability.

We’re always working on the next Thermapen. For over 30 years, we’ve been improving Thermapen's performance, design, features, and technology. Each generation is better than its predecessor. How much better? Thermapen NANO is 20 times faster than the original Thermapens from 1992! As technology improves, so will the Thermapen!
