This commercial-grade thermometer is used to avoid over- or undercooked food by testing your oven temperatures. It is made of heavy-duty stainless steel; the thermometer features a wide base and a two-way hook so that it can be placed or hung anywhere inside the oven. The large 2-1/4-inch dial with its high-visibility red indicator needle measures temperatures in both Fahrenheit and Celsius, ranging from 150 to 550 degrees Fahrenheit (65 to 290 degrees Celsius). Temperatures are also grouped into cooking zones, such as warm, moderate, and broil, for quick reference. Certified by the National Sanitation Foundation (NSF), this thermometer has been manufactured to high commercial standards. CDN covers the thermometer with a five-year warranty against defects.
