Combustion Predictive Thermometer with WiFi Booster | 8 Sensors | 900ºF Max Temp
Eight sensors, evenly spaced from tip to handle, give you the full thermal story of what's happening inside your food while it cooks. The top half can tolerate up to 900ºF. The hermetic brazed ceramic seal earns it an IP69K rating—the highest waterproof protection there is. You can vacuum-seal it for sous vide, blast it over open flame, or dunk it in a deep fryer. It's rated for things most thermometers would file a restraining order against.
The included WiFi Booster connects to your home network so you can monitor your cook from anywhere with internet. Basement to Bali. Couch to Copenhagen. The Booster's battery can fully recharge the thermometer up to 16 times, and when stored inside, the thermometer stays charged and ready for up to 9 months.
Combustion's physics-based Prediction Engine models heat dynamics and evaporative cooling to estimate when your food will be done. SafeCook™ tracks bacterial reduction at every step and tells you exactly when your meat hits USDA safety standards—while it's still tender. It does the food safety math so you don't have to pretend you remember it.
Requires the free Combustion app (iOS, Android, iPadOS, macOS). Works with Bluetooth (330ft+ range unobstructed) or WiFi for unlimited range. Full reading in 4–5 seconds. Battery lasts 90+ hours in cook mode at 5-second intervals. A 5-minute charge gets you 24 hours of cook time.
