The ultimate steak thermometer is easy to use and clear to read. Turn on the SteakChamp in the black activator, insert it into the raw meat from the side, and cook it from the start. A green double flash means the steak is medium rare; yellow means medium; red means medium well. Remove the steak from the heat at your desired doneness and let it rest. When the light stops flashing, the resting time is over and the steak is ready. The SteakChamp then switches off automatically. Suitable for grills, pans, and ovens. Heat-resistant up to 500°. Battery-powered (battery life: approximately 1,000 to 2,000 steaks). Includes a magnetic activator. Hand-wash with warm water and mild dish soap.
