The Weber iGrill Mini offers precision grilling, every time. With 150 hours of battery life, this two-inch magnetic thermometer seamlessly pairs with a compatible smart device via the Weber iGrill App to immediately alert you once your food has reached your target doneness. The iGrill Mini includes Smart LED Technology that guides you through a four-color food progression spectrum, so you’ll never have to lift the lid on your grill or smoker and interrupt the cooking process. Green means that you’re ready to go, yellow indicates that you’re 15-degrees from your target temperature, orange signifies that you’re 5-degrees from the target temperature, and red means your meat is done and it’s time to eat. Clean the unit with a lint free cloth and non-abrasive cleaner. Never submerge in fluid, it is not waterproof.
