This is Combustion Inc. as it is meant to be used.
Start with the thermometer, because that is what justifies everything else. Most wireless kitchen thermometers measure temperature at a single point. That sounds reasonable until you start thinking about what you actually need to know. Meat, fish and poultry are not homogeneous materials. Heat spreads unevenly from the inside and outside depending on the shape, fat content and density of the food and the oven’s temperature profile. The coldest point inside a thick sirloin steak or a whole chicken leg is rarely exactly at the tip of the thermometer. A single measuring point gives you a number. That is not enough.
The Combustion Predictive Thermometer Generation 2 contains eight sensors along the probe. Four TrueCore® sensors sit in the tip and lower third, surrounded by the food, and always identify the coldest point inside the meat regardless of how the probe is angled or where it is positioned. Three TrueSurface™ sensors cover the upper section and measure actual surface temperature, crucial for knowing when the surface is caramelising correctly or when the crust on a steak is ready for turning. The eighth sensor, TrueAmbient™, sits by the handle and measures the air temperature in the oven, barbecue or frying oil, completely separately from the heat of the food. Together, the eight provide what Combustion calls Total Temperature Awareness®: a complete real-time temperature profile from centre to surface to surroundings, all in one instrument.
Just as important as the hardware is the algorithm. Physics-based Prediction Engine™ runs in real time against the sensors’ continuous stream of data and models the heat flow inside your particular food under your particular conditions. It calculates exactly how much time remains until the desired core temperature is reached, compensating for carryover cooking, the fact that the temperature inside the meat continues to rise after it has been removed from the oven. That is the difference between guessing from experience and knowing from calculation. SafeCook™ simultaneously calculates bacterial reduction against USDA-FSIS and FDA food safety standards and indicates exactly when the food is safe to eat without having been overcooked.
The probe is 4.8 mm in diameter and 97 mm long, hermetically sealed with a ceramic-to-metal braze rather than a rubber seal. IP69K is the highest protection rating available and means the thermometer can withstand direct high-pressure spraying with 80°C water. It is vacuum-tight and works just as well in sous vide at 55°C for 48 hours as on a charcoal barbecue at 300°C, in a deep fryer at 180°C or in a wood-fired oven. The temperature range extends up to 482°C. The accuracy of the four internal sensors is ±0.2°C within the range relevant to cooking. The battery uses LTO, Lithium Titanate Oxide, cell chemistry, a choice that prioritises durability over capacity: 90% of the original capacity remains after 1,000 charging cycles. Five minutes of charging provides 24 hours of cooking time. Fully charged, it lasts for more than 90 hours.
The WiFi Booster is the accessory that solves the thermometer’s three practical problems at once. Charging: the built-in battery can fully recharge the thermometer up to 16 times without the Booster being connected to a wall socket. Stored in the Booster, the thermometer remains fully charged and ready to use for up to 9 months without you having to think about it. Range: the Booster connects to your WiFi network and forwards the thermometer’s data to MeatNet™ Cloud for real-time monitoring in the Combustion app from anywhere in the world. It also extends Bluetooth range by a further 100 metres per unit in the network. Connectivity: the Booster relays signals between all Combustion devices on the network and acts as the backbone of the system when you are running several thermometers or combining them with the Display. The Booster measures 165.8 × 15.8 × 14.4 mm, charges via USB-C and reaches a full charge in 60 minutes.
WiFi Display is the physical control centre. A 2.8-inch FSTN LCD with adjustable RGB backlighting, built-in WiFi and a built-in magnet with 27 newtons of pull force, measuring 79 × 79 × 16 mm. It communicates via Bluetooth 5.4 with up to four Predictive Thermometers at the same time and shows core temperature, surface temperature and ambient temperature in real time, plus a countdown to the correct result based on Prediction Engine™. You set the target temperature directly on the display, attach it to the refrigerator or oven door with the magnet and cook without touching your phone. Connected to WiFi, it sends data to MeatNet™ Cloud and works with the Booster to keep the entire system connected and synchronised. Battery life is 28 days under normal operation and up to 6 months in storage without charging. There is a built-in kitchen timer independent of the thermometer function and an alarm when the target temperature has been reached.
The package contains Combustion Predictive Thermometer Generation 2, WiFi Booster and WiFi Display. The Combustion app is free and available for iOS, Android, iPadOS and macOS, M1 or later. WiFi connectivity and cloud monitoring require the app. Combustion Inc. was founded by Chris Young, co-author of Modernist Cuisine and founder of ChefSteps and Joule. The Kitchen Lab is one of only a handful of Combustion Inc. retailers in Europe.
In short: the thermometer with eight sensors and a prediction engine, the Booster that charges it and connects the entire system to WiFi, and the Display that shows everything and counts down to the correct result without your phone ever leaving your pocket. The most complete way to get started with Combustion, and the only package that includes all three components.
