What makes the Combustion Predictive Thermometer unique?

Here’s some of our exclusive features you won’t find anywhere* else:

  • 8 sensors (the most of any wireless thermometer)
  • Total Temperature Awareness™ throughout and near the food
  • TrueSurface™ Sensors
  • Onboard processing (and memory)
  • Built-in food safety
  • The only physics-based predictive engine 
  • The most temperature measurements per second
  • The longest functional battery life
  • The smallest holes in your food (the slimmest full probe and least volume displacement)

 (*At least until the other guys try to copy us again)

How is the Combustion Predictive Thermometer different from other wireless thermometers? I want more details.

The Predictive Thermometer (CPT) has 8 sensors, the most of any wireless thermometer. 

7 sensors are spaced equally along the length of the “probe” and the 8th sensor is placed in the handle to measure the ambient temp near the food (more about that below). 

It shows you all the temperatures from the surface to the center (and the external “boundary layer”) for the duration of the cook. This “Total Temperature Awareness™” means you know how evenly your food is cooking, how things are changing, and when exactly it will be done to your exact specified temp.

You eat more than just the center of the food. So you need a thermometer that measures all the temperatures!

The CPT was the first thermometer to put multiple internal sensors (TrueCore™ Sensors) into the tip. Those “extra” sensors let the CPT find the lowest internal temperature even if you missed the mark. 

It’s also the ONLY thermometer that has the ability (and the sensor placement) to measure the true cooking temperature at the surface of the food (TrueSurface™ Sensors). Pay attention to that temperature! It’s the secret to consistent, precision cooking.

The temperature at the surface of your food is the best measure of heat being applied.

The surface is nowhere near as hot as the surrounding oven - that's because your food sweats. As it does, the evaporating juices cool the surface to a lower cooking temperature.

How much? It varies, and that's why we measure at the surface.

By measuring surface temp, you can adjust your oven or smoker to control the true cooking temperature, bringing a precision to your cooking that was previously only possible with sous vide.

The CPT is also the only thermometer with onboard processing. This may seem like a nerdy call-out, but because we have a tiny computer in the thermometer itself, doing all the intensive cooking math, it’s far more reliable.

All other wireless sets outsource the thinking to a second device, whether that’s a phone or a base station of some kind. So your data (and therefore your cooking outcome) is dependent on a continuous connection between their dumb probe and the smart device. That introduces multiple points of failure.

Don't I only need to know the temp at the center?

For perfect results, you want to measure that and more.

The Predictive Thermometer measures the center (core) temp, the surface temp, ambient temp, and everywhere in between. 

What’s more, our extra sensors (8 total!) allow us to find the center, even if you miss it. This often happens with compact food like a filet mignon or with irregular food like a whole chicken.

All wireless thermometers have a minimum insertion depth (ours is 2in/50mm). If our tip sensor ends up past the center, the lowest reading from the other internal sensors reveals the true core temp.

With our True Core technology, near misses are not misses. In fact, we recommend you push the tip a bit further than the visual center. We'll find and instantly report the lowest temperature so you can be totally confident it comes out just right.

Why do I need an ambient sensor? Isn’t that just the oven temp?

Nope. In fact, it’s not uncommon for the oven temp to be off by 100ºF or even 200ºF! 

New CPT owners are often surprised by this. We’ve gotten emails saying “this can’t be right!” But it is.  

As it heats up, water inside your food evaporates into steam (212ºF). The steam tends to linger near the food, mixing with the hot oven air, and creating an invisible fog which - while still quite hot - is significantly cooler than the rest of the oven.

This is not actually bad news (it helps your food cook more evenly) but it is a shock to many people. 

Because the Predictive Thermometer measures the ambient temp near your food (TrueAmbient™ Sensors), it captures the effect of this boundary layer. 

If you want to see + hear more about this, Chris made a YouTube video that explains it really well. It also shows how convection (airflow) affects ambient temp. (Skip to 5:26 if you’re in a hurry to get back here.) 

[Warning: video may make you hungry.]

I have a different question that is not answered here?

The first thing to try is our help center/FAQ. You can search by topic and learn more than you ever needed to know about the Predictive Thermometer and other Combustion tools. 

If you have no luck there, our subreddit is a good bet.

Anything else I should know?

Oh my yes. 

The Combustion Predictive Thermometer was designed to be a tool for professional chefs, but to also be easy to use by cooks at any skill level. 

Read as much as you can. The deeper you dive, the more I think you’ll appreciate the genius (and occasional madness) of what we’re doing. 

We’ve been very fortunate to have found a community of like-minded cooks who appreciate the extra insight and deep data our tools can provide. And we’re regularly surprised by the new and unusual uses that people are finding for the Combustion Predictive Thermometer (Beehives? Raw milk?). 

If you like cooking and science and the science of cooking, welcome. You’re in the right place. 

If you’re not sure about the CPT yet, do your research. Watch Chris’ videos - they’re full of surprising cooking science and practical techniques. Read the posts on our subreddit - there’s a lot of really specific discussion about how to use the thermometer and the people there are always pushing the limits. 

There’s also a ton of info on our help center, searchable by topic and keyword. 

Or you could always just jump in - we stand behind all our products with a 30-day money back guarantee. 

If the Combustion Predictive Thermometer doesn’t improve your cooking outcomes, or your process, or if it’s just not your bag for whatever reason, return it for a full refund of the purchase price.
