Description
The ultimate in smoker surveillance plus our entirely wireless draft-control fan and the new 2nd generation Predictive Thermometer.
Precision temperature control
The Combustion Engine™ is a wireless blower that teams up with a Giant Grill Gauge and Predictive Thermometer to maintain rock-steady temps for 24+ hours on a single charge.
The Combustion Engine receives grill temperatures directly from the gauge or thermometer and adjusts its variable-speed fan to hold it right in the sweet spot - locking in a perfect smoking temp for long periods.
Watch your meat from anywhere
The Giant Grill Gauge connects directly to your Combustion Engine and your Predictive Thermometer, and streams temperature data to MeatNet™ Cloud directly with its onboard WiFi! Compatible with most grills and smokers.
Cook longer (and hotter and wetter)
The 2nd generation Predictive Thermometer still has the most sensors of any wireless thermometer (8!) to measure everything from the surface to the center. This tolerates extreme cooking temps of up to 900ºF. And it’s suitable for vacuum-sealing (hello sous vide!) and has the highest ingress protection possible (IP69K). It can now run up to 92 hours on a single charge, all while conveying more data – and refreshing 6-12x faster than competitors.
And it has all the insightful exclusive features that set Combustion apart - things like the first and only live food safety calculator (SafeCook™). Or how about a unique Physics-based Prediction Engine™ that models heat-dynamics and evaporative cooling to accurately predict cook time? We could go on and on (and don’t worry, we do, elsewhere).
Set contains:
- Giant Grill Gauge with huge display, built-in WiFi, 1000ºF temperature limit
- Combustion Engine – the only entirely wireless, rechargeable blower
- 2nd Generation Predictive Thermometer - 8 sensors, hermetically sealed, 900ºF (482ºC) max temp
