The Gauge replaces the existing dial thermometer on many grills and smokers. Check the mounting area before choosing a mount:

Thermometer hole: 5/32–1/4 in
Flat mounting area: 4.3 in (109 mm) across
Clearance around the mounting point: 2.5 in (64 mm)

Heat Shield: for top-mounted thermometers or hotter lids, up to 750°F (399°C). Heat Deflector: for front or side mounting, up to 600°F (316°C).

Some ceramic grills need an adapter plate, and thick walls may need a longer sensor than the Gauge’s 86 mm tube. If your grill needs an adapter or does not meet these measurements, email support@combustion.inc with your grill’s make, model and a photo to confirm the fit before ordering.

No. Display and Giant Grill Gauge kits without a Booster include a charging cradle. A Booster adds cordless recharging. Use your own USB-C cable and standard 5V USB power source; neither is included.

Your Predictive Thermometer sends readings by Bluetooth. A WiFi Booster, WiFi Display or Giant Grill Gauge receives those readings and sends them on to your phone.

The Predictive Thermometer sends readings by Bluetooth to one of three alternative WiFi accessories: Display, Booster or Giant Grill Gauge. The accessory connects onward to a phone by Bluetooth or WiFi.

You only need one of these three WiFi accessories.

Nearby: Long Range Bluetooth

Your phone can receive readings directly from the thermometer or through a nearby Combustion accessory. The accessory relays the signal so you can move farther from the thermometer. No WiFi is needed.

Beyond Bluetooth range: WiFi

Connect your accessory to WiFi with internet access and sign in to the Combustion app. You can check food temperatures and time until ready wherever your phone has internet access. Changing a target temperature in the app still requires a local Bluetooth connection.

What affects Bluetooth range?

Walls, metal and foil reduce range. Keep your accessory where it receives a good signal from the thermometer; WiFi cannot replace that first Bluetooth connection. The second-generation thermometer transmits at +8 dBm, with an unobstructed Bluetooth range rated at 330 feet (100 meters).

Yes. Each WiFi accessory supports up to four Predictive Thermometers. Add another thermometer with its standard charger to cook more foods at once. You don’t need a Booster for every thermometer.

You can also add another display. Leave a Giant Grill Gauge on your smoker and add a WiFi Display in the kitchen to see the same thermometer’s readings in both places.

Linked Combustion tools form MeatNet, relaying readings between them. Adding a tool where it receives a good Bluetooth signal provides another path for the readings. Both WiFi accessories can connect to the internet; you don’t need to choose just one.

Add a WiFi Booster, WiFi Display or Giant Grill Gauge on its own. All three work with first- and second-generation Predictive Thermometers, so you can add WiFi without replacing your thermometer.

Rave reviews from real cooks

Out of the frying pan and into the 🔥

With its 900 ℉ max temperature rating and brazed hermetic seal, the Predictive Thermometer doesn't just survive high heat — it thrives in it.

Any technique, any temperature the Predictive Thermometer can handle it.

Total Temperature Awareness®

No more cutting board surprises. From the smallest filets to largest roasts, TrueCore® pinpoints the slowest-heating part with 8 evenly spaced sensors.
8 sensors measure what others miss. Track temps from the surface to the center, and build your chef-like instinct for controlling heat.
8 sensors feed our Prediction Engine™ too. Sensors and software work together – using real heat transfer physics for perfect timing.

Safecook™ Complete

99.99999% bacteria destroyed.

Stop overcooking, just to be safe. Pick your protein and let SafeCook™ tell you exactly when it's safe and delicious. It tracks both time and temperature throughout cooking to calculate when your food is safe - so you'll never have to overcook "just to be safe" again.

Food safety isn't merely just high temperature - what matters is time spent at bacteria-destroying temperatures.

The old way? Temperature-only overkill.

Traditional guidance like "cook chicken to 165°F" was created because there wasn’t an easy way to track both time and temp. These simplified rules guarantee safety through overkill – brute force thermal annihilation. Result: overcooked food.

The SafeCook way? Time + Temperature.

The Predictive Thermometer stays in your food throughout cooking, tracking both time and temp. It continuously calculates bacterial destruction until your food reaches official safety standards—usually at a more delicious doneness.

See the difference

Chicken breast cooked at 150°F for about 3 minutes is just as safe as chicken cooked all the way to 165°F. But it's fork-tender and juicy, not dry and overcooked.

That's because SafeCook measures what matters: the total time spent at bacteria-destroying temperatures.

There’s an app.

(But it’s not quite as cute as the Display)

Our apps for iOS, Android, WatchOS, and MacOS turn your devices into powerful cooking companions. Dive deep into real-time data or keep it simple — it's your call.

Just the essentials.

Focus on essential cooking temps: core, surface, ambient...

All. The. Temps.

...or view all 8 sensors to see exactly
how heat moves through your food from the surface to the core.

Perfect timing.

Simply enter a target temp—in a few minutes you’ll get a countdown that tells you exactly when your food will be ready.

Visualize better cooking.

Take a closer look at the graph to really understand how heat is flowing and perfect your cooking technique.

Keep your food safe and delicious!

SafeCook™ tracks time at temps and tells you exactly when your food is safe to eat. No need to overcook “just to be sure.”

Constant innovation, on us.

Regular updates bring new features and boost performance, making your Predictive Thermometer work even better over time. Built-in upgrades with every update!

Oh, did we mention?

The Combustion Predictive Thermometer is still the thinnest, most accurate, and longest running wireless thermometer? It’s also the only open source wireless thermometer available.
