Monitor Food, Storage, Equipment, and Room Temperatures with Commercial Thermometers Commercial thermometers are vital kitchen tools that ensure food is safely prepared, cooked, and served! Use probe thermometers to determine when meat and other foods are cooked to proper temperatures, or use wall-mounted styles to maintain consistent working temperatures in your kitchen or dish room. Denson also carries restaurant thermometers that measure the temperature of your refrigerator, freezer, oven, or dishwasher.
