Smoking meat and fish properly can take days. So, rather than going out to the smoker to check the temperature time and time again, simply install a RediChek Remote Wireless Smoker Thermometer and rest at ease. This handy thermometer monitors smoker air temperature and food temperature from up to 100 feet away. And, if the temperature drops too low or jumps too high, the RediChek alarm goes off, so there are no spoiled batches-just certainty that every batch of smoked salmon is perfection. The RediChek can also be used with an oven or grill for peace of mind while baking, barbecuing, and broiling and for fewer trips to the kitchen. Best of all, the RediChek is wireless, so installation is a snap. Your purchase includes four AAA batteries for out-of-box use.
