The RediChek Remote Cooking Thermometer takes all the guesswork out of knowing when your meats on the grill or in the oven are done and cooked to perfection. This thermometer features a stainless steel probe and 42 inch wire to take accurate readings in the oven or the grill. Monitor food doneness up to 100 feet away. The transmitter doubles as a docking station when the thermometer is not in use. Program the thermometer to the desired temperature, and RediChek will alert you by beeping and flashing when the desired temperature has been reached. Requires four AAA batteries (not included).
