The iGrill2 Smart Grilling Thermometer is the ultimate grilling tool that makes it easy to achieve grilling perfection. Powered by a free iOS and Android app and a wireless Bluetooth Smart connection, knowing exactly when to take your meat off the grill has never been easier. This grilling thermometer includes two, water-resistant, color-coded food probes that can withstand temperatures up to 716 degrees Fahrenheit. Expand both your iGrill2 and your convenience with up to four total food probes. An illuminated display allows you to check the temperature on the iGrill2 whether you are grilling during day or night, and the convenient magnetic mounting lets you place the iGrill2 just about anywhere. You can use the adhesive disc for mounting on non-magnetic surfaces. The iGrill2 has a proximity wake-up, which can intelligently sense when you are too far away from the unit to view the display and goes into a power save mode until you come back into range. With the 150-foot range of the Bluetooth connection, you can keep a close eye on your food while you are inside visiting with guests, watching the game or preparing a side dish. The free Weber iGrill app, available in the App Store or Google Play store, is your central dashboard that monitors the temperature and receives alerts when your food is ready to enjoy. The Weber iGrill App has support for multiple devices and comes loaded with handy digital grilling tools such as custom alarms, exclusive recipes, temperature graphing, and social sharing.
