Make perfect steaks every time with the Intelligent Steak Thermometer. Simply insert the cordless stainless steel probe into your raw steak and place it on the grill. The color-coded LED light tells you when your steak is ready: green=medium rare, yellow=medium, red=well. Grilling multiple steaks? Just use one device to monitor them all. It's the safe and hygienic way to prepare great-tasting beef, game or fish. Heat resistant to 900°F, it can also be used in a frying pan or oven. Built-in battery is designed to last 20 years (roughly 1,000 uses).
