Download Classic Thermapen Operating Instructions
Order a Thermapen today and we'll throw in a copy of our new 20 page guidebook: "Using Your Thermapen: A Guide to Better Food Through the Proper Use and Care of Your Splash-Proof Thermapen" at no extra charge. The guide features basic cooking temperature principles, step-by-step instructions for customizing and cleaning your Thermapen, special considerations for getting just the right doneness with meat, poultry and fish, QuickTips, Frequently Asked Questions, diagrams, and more. Plus, there's a handy chart of food safety and chef-recommended temperatures on the back!
Originally, we manufactured the Thermapen in gray only. Later we added all the food-safety color-coding versions. Many people in the food industry use color coding to prevent cross contamination by dedicating tools to specific food products. That way, a knife, cutting board or thermometer that is used for say, raw poultry, won't end up contaminating fresh vegetables like salad greens.
Had a knock off thermometer for a while and it took a long time to get a reading. I love my Thermopen fast and accurate. I'll be ordering more products soon.

Classic Super-Fast Thermapen is a professional tool (originally designed for commercial kitchens, labs and manufacturing plants) that has become the top consumer cooking thermometer for home use. Its popularity among celebrity chefs, cooking magazines, top foodies, bloggers and competition BBQ teams has made the Thermapen into an essential tool in the best-equipped home kitchens and backyard BBQ rigs.
Made by Hand in England, the Thermapen is faster and more accurate than any other cooking thermometer on the market. Competitors have tried to copy the Thermapen with mass-produced products made in China and have flooded the housewares market with slower, less-accurate knock-offs. However, when compared to true competing commercial thermocouple thermometers, the Thermapen is not only faster and more accurate, it's also less expensive!
The Thermapen's speed and accuracy will reveal more about food and cooking techniques than you ever imagined. You'll learn that temperatures are always changing; a roast is never the same temperature throughout while cooking. If you want to know what's really going on, get a Thermapen.
If you want to experience speed and precision (traceable to National Standards) and you're on a quest for culinary perfection, you will want a Thermapen. Add up the expense of wasted meats alone and you'll justify the cost of this professional tool.
A Thermapen can be used for virtually anything that needs to be cooked or chilled. Use it on meats, fish, casseroles, re-heated foods, breads, cakes, deep frying and candy. You don't have to have a Thermapen to be a great cook; however, more than one celebrity chef and several food writers have testified that a Thermapen will make you a better cook...AND, you can choose your own color! Order one today.

Great while they work
I'm now on my second dead Thermapen.
They have been treated kindly, not exposed to water, but I find they last for about 3 years of occasional usage in my home kitchen. And when I say occasional, I mean once or twice a week.
The battery was just changed on the second one, and it worked for a short time, and no longer works. I just looked up my receipt. It's 3 years old.....
The first one I had to disassemble and clean out the grease that had developed in the swivel. While that brought it back to life, it died not too long after again.
Just a poor design. For the cost of these, they shouldn't do this.

Happy with purchase. Cooked 3 pork butts all three turned out perfectly. Fast shipping and easy to use.
Have a question? Ask owners.
Start typing and see existing answers.
Why did you choose this?
Can I use this as a candy thermometer?
Yes, you can. In fact, the Thermapen is our preferred choice for candy making. It's fast. It's accurate. It's the perfect tool for keeping on top of the fast-moving temperature changes that occur during the last moments of a candy-making cook. We highly recommend the Thermapen for this application.
Does this Thermopen come with a certificat of calibration?
Yes, it comes with a calibration certificate.
Different parts of meat measure different temperatures, how do you know which one is accurate?
Unlike dial thermometers, where the sensor can be in the shaft of the probe, the temperature sensor in a Thermapen is in the very tip of the probe. This is important. It means, wherever you put the tip of the probe, that is where your Thermapen is measuring temperature.
Different spots of meat are different temperatures. The best way to measure the doneness of meat is to push the probe tip just past the center of the food while it is cooking (being careful not to go all the way through) and to pull the probe tip back up through the food until you find the coolest spot. You'll actually notice the numbers on the Thermapen display change as you move the tip around. That's because different parts of the food are at different temperatures while it cooks.
If you have any concerns about the accuracy of your Thermapen, or any other thermometer, the best way to test them is with a properly made ice bath test, as it’s a standard laboratory test that is easily replicated at home. If your Thermapen is accurate, it will read within ± 0.7°F of 32°F (31.3 to 32.7°F). If it is reading accurately in this test, you can rest assured that it is reading accurately in various spots in food and at higher temperatures. Directions for conducting a proper ice bath can be found here:

can you use a classic thermapen to measure skillet temperature before searing a steak?
If the pan has oil or butter in it, then yes, you can use your Classic Thermapen. However, if your skillet is dry, you'll want to use an infrared gun, as they are used to measure surface temperatures.
You can find our selection of Infrared Guns here:

Does it read water/liquid temperatures too?
Yes, it does. You can use a Thermapen to take the temperature of any food or liquid (and many other things, too)!
Display rotates?
The Classic Thermapen's display does not rotate. You'll want to look at the Thermapen ONE instead, as it has an auto-rotating display. It's available here: https://www.thermoworks.com/thermapen-one
What is the button inside next to the battery?
It is the trim adjustment. You can read more about it in the Operating Instructions that came with your Thermapen. You may also find the Operating Instructions online here:

Calibration and Trim Adjustment Instructions may be found here
:https://www.thermoworks.com/pdf/user_manuals/Thermapens/Thermapen_Splash_Proof_Calibration.pd
fNote: If the Thermapen is within specifications, we do not recommend using the trim adjust feature.. It should not be needed in normal use.
Can you use the thermapen to check how hot grease is?
Yes, you may.
Is there a warranty on this?
Yes, Classic Thermapen comes with a 2-year warranty. You can find the warranty terms here:
https://www.thermoworks.com/product-warranty/
can a thermapen be used as an oral thermometer?
No, it cannot. We recommend that you look at WAND™ - No Touch Digital Forehead Thermometer, which is FDA-Cleared for taking human temperatures. You may find it here: https://www.thermoworks.com/wand
great device
Great service from older unit with slower probe and will pass it on + good pricing.
My son-in-law needs a meat thermometer, and I have a Thermapens myself, so I know he can depend on this thermometer.
