The Primo Digital Thermometer will help to ensure that your food and grill are at the appropriate temperature at all times. Featuring a base and wireless receiver, this unit provides accurate temperature readings from up to 300 feet away. By placing one heat-resistant probe wire inside your Primo Grill and the other probe into the meat, you can monitor the dome temperature as well as the internal temperature of the meat. The wireless receiver with LCD screen beeps and flashes when meat or temperature goes above your programmed temperature. This Primo Thermometer also features a Count-Up & Count-Down timer and a back light for use at night. The receiver has a belt clip and built in stand for keeping a close eye on your meal. The transmitter has a removable wire stand that also becomes a hanger which can be used with your grill. A special smoking chamber probe wire comes with a clip to attach to grill rack.
