Feature: 1. Before you put the turkey in the oven, put it in the oven. Once the meat is cooked, the center of the timer will pop up to remind you. 2. These disposable thermometers accurately determine (within +2 ℉ or ‑2℉) the temperature of poultry, meat or fish, making it easier to cook. 3. Activate between 175℉ and 180℉ and cook until the colored head of the thermometer pops out. 4. The pop‑up thermometer is easy to insert, just insert and cook, ensuring that the timer does not touch the bones. 5. If the pop‑up thermometer is used with poultry, insert it into the left or right side of the poultry's sternum.
