Can it be used in a ____?

If you can cook meat in it, then almost certainly yes. Grills, smokers, ovens, ranges, pans, induction, air-fryers, rotisseries, slow-cookers? All good.

Sous vide? Yes. Deep-fryer? Not yet, but we’re working on it. Microwaves are no-go. Sorry, Sparky.

The handle is safe up to 575ºF. The internal components are good up to 212ºF, but don’t worry: they’re insulated by the food while it cooks.

How’s it different from other wireless thermometers?

8 sensors. Competing wireless thermometers have 2 (at most!).

Those “extra” sensors are a huge advantage for you. They create context so we can figure out the effective size of the food, how evenly it’s cooking, and exactly how things are changing. This leads to more accurate predictions. More data equals less guessing.

By comparing temps at each sensor, we can find the lowest internal temperature every time, even when you miss the “center.” We’ve all done that, because most of the things we cook aren’t a uniform block. That doesn’t matter with the Predictive Thermometer.

The extra sensors also allow us to locate and measure the surface temperature. If you want more consistent results from your favorite recipes, keep reading.

What’s special about surface temperature measurement?

Surface temperature is the secret to consistent, precision cooking. That's because the temp at the surface of your food is the temperature the rest of the food feels.

It's nowhere near as hot as the surrounding oven. That's because your food sweats. As it does, the evaporating juices cool the surface. How much? Depends on the food. That's why we measure at the surface. And by the way, we’re the only one who can.

By measuring surface temp, you can adjust your oven or smoker to control the true cooking temp, bringing a level of precision to your cooking usually only possible with sous vide.

Why Bluetooth?

The newest Bluetooth standards gives us the strongest possible signal, and it’s far more consistent than WiFi. No dead spots.

Secondly, there’s no “handshake” problem. A WiFi router requires sign-in every time you start up (or restart) a device (sometimes it happens automatically, but not always). That’s the last thing you need when your pork chops are in the oven.

The way we have it set up, it’s no hassle. If the thermometer is on, it’s broadcasting. If the display (or your mobile) is on, it’s receiving that broadcast. It’s just simpler that way. You shouldn’t need tech support to cook a ribeye.

Can I hack it?

Yes. Easily. All the temperature data is broadcast in the open, where you can grab it with any Bluetooth device. We use an open standard so clever dev-type people can make their own apps.

It’s impossible to build an app that’s all things for all cooks. We know folks will want specialty apps more suited to certain styles of cooking, and that’s great. Go hog wild! Our stuff is free to build on, and what you build remains yours.

Open standards also mean the Predictive Thermometer will be able to work with many smart appliances. It can be the “eyes” of a connected kitchen, telling appliances what they need to know so they can (for instance) adjust the heat level when needed.

Hello. We’re Combustion Inc.
We build nice things that make cooking enjoyable.

You don’t need much to prepare a great meal: A sharp knife (like actually sharp), a few good pans, and a modest assortment of other tools are enough. You should definitely have a good digital thermometer. And we think it should be smart enough to take the guesswork out of cooking. We made ours that way, so that your food will be just right, every time.
