With full readings in only 2 to 3 seconds, the Super-Fast® Thermapen is the world’s best in speed and accuracy. Advanced technology makes the new Thermapen Mk4 even more intuitive than previous models. Hold it in any direction and the display automatically rotates right-side-up so you can read it in any position—in either hand, straight up or down; read temperatures without cocking your head.

  • The Mk4 knows when it’s dark and turns on the backlight for you, making it easy to read at dusk or in complete darkness with maximum battery life. Or, just touch the sensor window anytime with your finger and the display lights up. Leave the probe open and the Mk4 stays on while you use it. Set it down, and Sleep Mode saves battery power. Pick the Mk4 up, and it turns on again instantly. Close the probe when you’re done cooking and the unit stays off for storage. High-tech, intuitive, fast and accurate.

    Available in Multiple Colors

    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.

    That was the reason we did multiple colors for the Thermapen. Of course most people buy a color variety simply according to personal preference. Even in commercial applications it seems most people buy colors so they can quickly tell who belongs to which Thermapen (blue is Fred's, yellow is Cathy's, etc…)

    In 2006 we added black and orange which weren't even on the color coding system. If you have a color preference that we don't make yet, email us and we'll keep track of your vote.

    Standard Color Code:

    Red = raw meat, raw beef and pork.

    Blue = raw seafood

    Yellow = raw poultry

    Green = produce

    White = dairy or bakery items



    Thermapen Mk4 FAQ

    1. Where can I buy the Thermapen?

    You can buy it right here online. There are only a few authorized dealers, (watch out for counterfeit Thermapen look-alikes). There are a few retail outlets in the U.S. and Canada that stock the Thermapen.

    2. Why don't more retail outlets carry it?

    Most retailers want to more than double their money. The big name chains want the most. If a product costs them $4, they want to charge you $10. The Thermapen is already priced at "Trade Pricing". Meaning, this is the price we sell it to commercial food service users and health departments. And, we offer it to the general public at the same price. Big retail chains would have to charge you much, much more and they'd still be mad that we would take your order at a lower price. The retailers that do carry the Thermapen are not making their normal mark-up so thank them if you buy there!

    3. Where can I buy replacement batteries?

    The Thermapen Mk4 uses one AAA battery, which are commonly found at Wal-Mart, Target, and other stores.

    4. How long should the battery last?

    The new Thermapen Mk4 with one AAA battery should give you about 3,000 hours of use. This number is based without using the back light. If you grill a lot at night the number will be reduced.

    5. Will the Thermapen tell me when my meat is done?

    Not exactly. Instead it (very quickly) tells you the actual temperature and you decide if that is "done". We can give you the USDA guidelines for food safety but you should consult your favorite cookbooks, TV shows and recipes for advice not only on safe temperatures but the best cooking temperatures for flavor and texture. Also remember that individual preference is very important.

    6. Other digital cooking thermometers are cheaper. Why pay more for a Thermapen?

    In use there's a big difference. Don't take our word for it. Check our Reviews page to read the many reasons written by others. Cheaper thermometers are limited by the technology that they use. These can be mass produced for just a few dollars. On the other hand, the Thermapen is hand-assembled and hand-tested and uses a professional thermocouple circuit design. This design costs more to make than the cheap thermometers.

    7. Why is the Thermapen so much faster than other cooking thermometers?

    The main reason is the professional thermocouple technology that we use instead of mass-produced thermistor technology. Thermocouples are recommended by the USDA for measurement of cooked meat products and thin portions. Go here to see what a thermocouple means in performance vs. a thermistor. We also use a reduced-diameter needle tip on the probe. Comparable professional meters cost $140 to $300 for the electronics and a similar probe! Some improvements were made in the sensor manufacturing process and the probe assembly in the new Thermapen Mk4 to make it just slightly faster than the original Super-Fast® Thermapen.

    “Having the Thermapen definitely took the guess work out of determining whether the chicken was ready. We expect to be using this tool everyday in the RainyDayKitchen. We just wished we had found it sooner!”

    First Look

    First Use


    “My birthday wish came true and I got a thermapen™. Yes, A THERMAPEN™. After screaming for a few seconds, I ran around taking the temperature of the air, the ground and generally anything that was soft enough to poke a needle into. The thermapen is ridiculously expensive, but the fact that it can take a temperature reading IN 4 SECONDS FLAT is truly amazing. It even came with calibration papers. CALIBRATION PAPERS! I love it more than anyone in their right mind should love a thermometer. I kind of want to carry it around in my bag and whip it out at restaurants. Okay, not really.”

    Cooking for Engineers

    "As you can see from the results, there is no comparison between the Thermapen thermocouple thermometer and any of the others. The speed is amazing - about one second for a ballpark value and two more for dead accurate. Three seconds is such a short amount of time that the time it takes to position the probe in the middle of the roast is almost the same time it will take for the Thermapen to take a reading. ...If you only have space for one thermometer, save up and treat yourself to the ThermoWorks Thermapen. It's fast. Very fast. It also comes calibrated with documentation to prove it. ...The probe tip is very thin (like a thick needle), so measuring the temperature of a 1/4 in. steak is no problem at all. The temperature range is greater than most thermometers and it's also really easy to read."

    Virtual Weber Bullet

    "There is no better instant-read thermometer than the Thermapen. While other "instant-read" thermometers take 20-30 seconds to reach a full reading, the Thermapen is done in just 4 seconds! ...Can be recalibrated or repaired if damaged. ...worth every penny."

    Roots and Grubs: Instant Karma

    “The Thermapen lives up to the phrase “instant-read”: you stick it in, and it tell you the temperature in four seconds, max, and usually more like two seconds.”

    Kevin Kelly Cool Tools

    “…once you've got one, you'll wonder how you ever cooked without it. The Thermapen takes all the guesswork out of the proper time to cook things. …this is THE best kitchen tool I have…”   -- Barbara Young

    “The best of the lot, the Thermapen by ThermoWorks, is truly instant, measuring the temperature inside your roast in seconds rather than minutes.”

    Nerd Approved

    “…it’s quick measurements and easy to read display make it a little easier than most. This product has been around for a while, and they are continuing to improve it. …Almost all comments from users are highly complimentary.”

    Nelson’s Weblog

    "Usually high tech gizmos are a failure in the kitchen, but the Thermapen is an exception. It's a true instant read thermometer: stick it in the food, wait two seconds, and you know the temperature to within one degree.

    It's expensive at $85, but it's so much better than conventional cooking thermometers it's worth it. The difference is it uses a scientific quality thermocouple instead of a cheapo thermistor." Meathead’s Hot Stuff Award!!

    “…get a really really accurate reading right now. …the probe is thin so it will not open a gusher when you pull it out. The heat sensor is extremely small, so you know you are reading just where you put it and not a lot of the meat around it. ...the only probe I use for ribs.”

    "This is the best cooking thermometer I've ever used. It's wicked fast… The temp sensor is at the very end of the probe, so there's no guessing whether you have it placed right. And there are no complicated controls to figure out."

    Braisin’ Hussy

    “I also got a Thermapen! These things are incredible. I mean, I have a digital themometer from Polder, but it takes like thirty seconds to read a temperature. This thing takes less than five seconds. It's SO COOL.”

    LA Weekly

    "This was one of the hottest items at a recent Master Food Preserver silent auction, and with good reason. The gel point in jams and jellies can be an elusive beast. But not when instantaneous accuracy is at your fingertips. Reaching the magical 220°F is much less painful, easier on the eyes, and involves way less clean up than the standard, bulky candy thermometer. Plate test, schmate test. Trust us, they will love it."

    KK Cool Tools

    "Over the past few years I've experienced everything from burnt caramel to undercooked turkeys and overdone steaks because of crappy thermometers. Most were either slow, inaccurate, or both, and it made for imprecise cooking.

    I left that all behind a few months ago when I started using a Thermapen digital thermometer."

    The Kitchn

    "So, what is a Thermapen and why is it so great? A Thermapen is a different kind of thermometer; it uses a different technology to read temperatures. Unlike cheaper, more traditional thermometers (which use thermistor sensors) the Thermapen uses what's called a thermocouple sensor. These are used in professional kitchens and other places where getting faster, more accurate temperature readouts is very important. The Thermapen condenses this technology into a relatively small thermometer probe."

    Q 4 Fun

    "The Thermapen is great for BBQing. The less you open your lid when cooking the better and when you do open the lid the less time it is open the better. The Thermapen takes a reading in about three seconds so you only need to open the lid for about 10 to know how your meat is doing. This translates into smaller temperature swings and allows your temperatures to stay more even for better cooking. The thermapen can also be used for other cooking like making jellies, jams and candy."

    BBQ Sauce Reviews

    "The Thermapen is one of the fastest, most accurate thermometers on the market today. It's a thermometer that's extremely popular for use by backyard grillers all the way up to competition BBQ teams."

    "The Thermapen from ThermoWorks isn't new but it is to me. And I'm so glad I found it."

    Kitchen Contraptions

    "Just open the probe and the Thermapen comes on. Close it and it shuts off. No buttons or switches to catch germs, confuse you and cause errors. We used our Thermapen over the past weekend to test various brew temperatures in our coffee makers to seek a perfect brew. Temp readings from the Thermapen were almost instant unlike our older kitchen thermometers, and we loved how easy it was to hold and put away."

    Grilling Companion

    "I really recommend the Thermapen. Again, the instant reading it gives you allows you to probe around and ensure that you have a perfectly cooked piece of meat."

    Seattle Times

    "The Thermapen digital meat thermometer, for instance, is fast and accurate."

    San Francisco Chronicle

    "...test the internal temperature with a British-made Thermapen. They're available in a Crayola array of colors..."


    "First of all, it's as sharp as an ice pick. It has a very slender needle, so it goes in easily. And it's digital, so it gives you an accurate read."

    Food and Fire

    "It gives you precise internal temperature readings in 3 seconds flat. There is no on or off button, swing the probe out and it's on (and yes, it was a hot one the day I got it). The very thin tip slides right into the meat and gives you a reading at the center of the food."


    "The Thermapen is the best instant read thermometer I've found."

When the new Thermapen was released I had to get one. I LOVE LOVE LOVE the new motion sensing design. It was a bit of a hassle to have to close and then re-open the probe after the auto-off kicked in to turn it back on (a first world problem to be sure). Now I just have to pick it and it's back and ready to use. I can't get enough of that feature. The backlight is great and the rotating display can be helpful at times as well. All in all I love the updates. The durability has been amazing as well. My 4 year old decided he wanted to give it a try and ended up shutting the probe in the oven door. He bent the probe. I gave the probe a little adjustment and it was back in place, good as new. I'm not so sure other thermometers would have been that resilient. $99 is a lot to pay for a thermometer but it has paid for itself over and over again. I'm quickly learning to buy the best and junk the rest. This is THE BEST!

Life Changing
It’s difficult for me to put into words what the Thermapen MK4 means to me and my overall quality of life, that of my family, and that of those that swagger up to the bountiful trough of smoked meats I provide. Comparing this instrument of gloriousness to any cooking or bbq’ing temperature accessory is like comparing the Death Star to a package of Kraft singles that’s passed its expiration date.

Number 1. Why does anyone have Kraft singles? That’s not cheese homie. That’s a guy in a lab coat tinkering with leftover yellow chemicals.

Number 2. This Death Star has no secret hidden design flaws.

I bought a competitive product one time - the most expensive one offered at the time - and you had to hold the sides of it for an “instant” reading. The only problem was their definition of instant was about the length of the movie Rambo First Blood, which I have on loop at my home because I’m an American. Also, I have a unique issue in that I have human hands made of skin and that proved problematic in holding the device over a blazing inferno of lump charcoal for any period of time past 4 seconds into Rambo.

When I first saw this product I thought hey… $100 is a lot of money. I could buy hatchet and a betta fish, or a subscription to the meat of the month club (which prolly exists). To say I was naïve is to say Trump doesn’t tweet enough.

The Thornelious Pentacular 5000, as I like to call it, is as advertised. This thing knows when it’s dark outside. A freaking light comes on so you can see it. How can it do that? Why is it so courteous? How many tiny Harry Potter sorcerers live inside this magical wand?

Sometimes, I forget it’s on - because I talk to people sometimes - and I come back and this thing has turned itself off. What kind of a backroom gangsta deal did this thing make with the battery companies to allow that? Did he trade them a bottle of Pappy for it? Two bottles of Pappy? No, prolly just one, because two would be like 50 grand.

I don’t understand Thornelious’s ways, but I sure do appreciate the results. You want rare, you want medium, you want medium rare - done deal, Thornelious is on it in 2 seconds (if he’s hungover). You want well done? Get outta here, leave now.

Sometimes, I take it to restaurants, partly because I don’t want him to feel left out, but also I like to leave it on the table, just to let the establishment know that I’m there, and I like to party. You think the guys in back don’t know Thornelious is out there? Oh they know… trust me… they know. They know they better not be bringing no 150 degree internal temp out to this hombre. Thornelious will Dikembe that steak into the cheap seats and wave his probe in defiance.

I open. I close. I probe. I make it rain with grilling perfection, thanks to the Thornelious Pentacular 5000, formerly known as the Thermapen MK4. If you don’t buy one, I look forward to your term paper on the benefits of communism and eliminating puppies.

Perfect, backlit and accurate
I had the classic before someone stole it. Replaced it with this one in pink, hopefully I get to keep it.

Love it. Also bought the leather case for it so I can travel with it. Some people travels with friends I travel with my thermometer. :)

Absolutely recommend this to everyone. Both pros and enthusiasts. Fits in your pocket and is fast and easy to use. The backlight sensor could be a little better. But put your finger over it to get the light to turn on.

Love it...
I've had the MK4 for about 10 weeks. It has become an essential, go-to, cooking tool. I just bought 2 more MK4s for my extended family. It's that good.

My son, a professional cook, carries the Super-Fast pocket digital for his work. If you want a toe in the water before committing to a MK4, start there.

If you get a MK4, be sure to get the silicon boot. The embedded magnets allow you to park your pen on the stove door, vent hood, refrigerator... it's extremely convenient.

By far, the finest thermometer available. There is nothing else that will improve your cooking more than cooking to the right temperature. Customer service is spectacular. Highly recommended.

Thermopen customer service
The Thermopen is a great tool. I use it for everything from yogurt and cheese making to baking to roasting meat.

I recently mutilated the battery door and sent an e mail to customer service about it. The promptly sent me a new one and included a package of Jelly Belly jelly beans in the package. The door was easy to change. All in all 5 star service.

No more overcooked meat. Now everything I cook whether on bbq, oven or stove top is perfect. I have the MK4. Would highly recommend it.

The gold standard
There are a lot of imitators (I went through 4 or 5 of them before taking the plunge and buying the real deal) but only one thermapen. Expensive, impossible to justify to a spouse, but once you've gotten used to its 3 second readings, there's no going back. The temperature assessment is so fast that you can literally pull it through a piece of meat and watch the temperature changing, like a topographical map. This enables a level of accuracy in cooking that is simply impossible otherwise. The shape and ergonomics are outstanding. I wish it was more affordable, but it's worth every penny.

Best Ever
This new version of the thermapen is a major improvement and is pretty much perfect. The wake feature is really helpful. Now you don't have to close and reopen the probe. That was always a pain when you would forget you left it open, it turned off and you have only one free hand.

The thermometer is only surpassed by the service from ThermoWorks. I had some issues with some other products I had purchased from them and was about to give up on future purchases. They went above and beyond to solve my issues and have won a customer for life. I have purchased about 10 thermapens and give them as gifts to chefs that work for me.
