The CDN DTP392 Probe Thermometer is perfect for roasting or grilling, candy making, and deep frying. Simply insert the probe into your food, place your food in the oven or barbecue and close the oven door (or grill cover) directly over the sensor cable. Set the temperature alert for USDA safe cooking temperatures. Features audio / visual alert, dual progress display with big digits, sliding mode switch, temperature guide, and adjustable stainless steel clip. Oven doors and barbecue lids close right over the heat-resistant 45-inch cable (not for use in microwaves). Large numerals on the LED screen display both the cooking and desired temperatures, and a switch on the back gives a choice of Fahrenheit or Celsius. The slim, oval-shaped thermometer has a hinged stand that lets it sit anywhere, as well as a removable magnetic holder that attaches it to the side of an oven or refrigerator. Measuring 3-1/4 by 5/8 by 2-1/4 inches, the thermometer comes with one AAA battery and a five-year warranty against defects.
