The finest candy thermometer we've seen, with a 9.5"-long stainless stem and a stainless clip to hold it to your pan. It measures from -40 - 450 degrees F, with an audible alert to warn you when your desired temperature or candy stage has been reached. The case is made of rugged ABS plastic and a sheath with a pocket clip is printed with a temperature guide. Auto shut-off, battery included.
