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. **Specs** 8 temperature sensors: 4 lower (accurate to ±0.4°F), 4 upper (accurate to ±0.9°F), 1 ambient (±2.7–8.1°F depending on range) Upper half: -5°F to 900°F (-20°C to 482°C) Lower half: -5°F to 220°F (-20°C to 105°C) Probe length: 3.8 in (97 mm) Diameter: 0.19 in (4.8 mm) Water resistance: IP69K / IP68 Battery: Lithium Titanate Oxide (LTO), 90% capacity retention after 1,000 cycles WiFi Booster battery life: 54 hours connected, 285 days standby with thermometer stored inside BLE 5.4 with Long Range support Open source iOS and Android libraries under MIT License Certifications: Bluetooth, FCC, RoHS, REACH, CE-Red, Food Contact Declaration **What's Included** 2nd-generation Combustion Predictive Thermometer WiFi Booster (charges thermometer, extends range, connects to WiFi) Charging cable (5V, 3.4V draw) Suitable for grilling, smoking, roasting, sous vide, deep frying, and any cooking method where knowing the internal temperature actually matters. • The only thermometer with a resume longer than most sous chefs' • WiFi range: unlimited, assuming the internet cooperates • Will survive temperatures that would vaporize lesser gadgets • Eight sensors because one was apparently not enough for these people
