The ET-73 RediChek Remote Smoker Thermometer is designed to monitor the internal temperature of the smoker chamber, as well as the internal temperature of the food being cooked in the smoker from up to 100 feet away! Forget about being glued to the grill while preparing a meal, insistently checking the temperature of food. Wander around worry-free, indoors or outdoors, with this handy wireless meat thermometer. If the temperature drops too low, or jumps too high, the RediChek alarm will go off and alert you to take action.
