Oven Probe measures 122ºF – 572ºF Digital LCD display shows elapsed cooking time, your choice of target temperature, and constant average actual oven temperature Average oven temperature is updated every 10 seconds Battery and probe included This new thermometer is a must for perfect baking of cakes and sensitive deserts. The Maverick BAKER’S OVEN THERMOMETER lets you know the constant average temperature of your oven throughout the cooking process. What’s more, it recalculates this average every 10 seconds, and compares it to the temperature target you have preset. It then alerts you if the temperature swings more than 15F above or below your target temperature. It updates this average every 10 seconds. The BAKER’S OVEN THERMOMETER measures the temperature by using a probe sensor with oven rack clip, and an insulated metal wire that passes between the oven door seal back to the unit. Ovens can vary up to 50 F from the temperature you set on the dial, and every oven is different. If you don’t know your oven temperature, your baking results can be poor. Terrific for proper cooking of roasts and poultry, too. Also features 20 hour count-up or countdown timer. Detachable stand for countertop use, hanging bracket for wall, and has magnets on back for sticking to metal surfaces. Single AAA battery included. Box size 6 1/2” x 7” x 7”. Master pack 6.
