With seven pre-programmed candy stages and one all-purpose temperature setting CDN's Digital Candy Thermometer (Model: DTC450) provides easy control over candy and other high temperatures. The thermometer has a stainless-steel probe that measures 8 ½ inches and can measure temperatures up to 450℉. The dual progress display shows two temperatures, the set temperature and the current temperature. Alert warnings will sound 3℉ before the low temperature, during the range, and at the high end of the range. During the two deep fry settings, the alert only sounds at the set temperature. Two (2) LR44 batteries and instructions included.
