Combustion Predictive Thermometer

  • 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®

  • 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!

Unconditional love, guaranteed.
