    • 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™

    • Holiday Rib Roast with the Predictive Thermometer

      No more cutting board surprises. From the smallest filets to largest roasts, TrueCore™ pinpoints the slowest-heating part with 8 evenly spaced sensors.

    • Beef Wellington with the Predictive Thermometer

      8 sensors measure what others miss. Track temperatures from the surface to the center, and build your chef-like instinct for controlling heat.

    • Turkey with the Predictive Thermometer

      8 sensors feed our Prediction Engine™ too. It uses real heat transfer physics to make perfect timing as simple as setting your target temperature.

    • 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.

    • Here's what makes SafeCook™ different

      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.

      Johannes Kristinsson

    • I have had great support experiences, as well. Even before using my thermometer for the first time, I received extra help getting going with this forum. It is nice when a company cares and follows up on things.

      u/BBQJohnny (reddit)

    • Excellent, very fast response. Took care of my questions/concerns immediately. It's refreshing to get great customer service these days.

      Luke Heafner

    • I mean, the service and support can't get much better. 10/10. Would email again! Ivy is great and Mr. Porkchop was very helpful as well.

      Andy Chan

    • Surprised these days to get any response from vendors.  But the high quality of this product indicates why I got a quick complete response.

      Mike Ferry

    • Obviously I'd have preferred not to have issues in the first place, but it's how you handle them that counts and this was A+. You really couldn't ask for better support.
