This thermometer instantly ascertains the temperature of foods, whether they're on the buffet line or being cooked. Its 1 inch dial, protected by a shatterproof plastic lens, displays temperatures from 0 to 220 degrees Fahrenheit. The thermometer comes with a pocket case and has a 5 inch stainless-steel stem. Should it seem to be off kilter, the thermometer can be recalibrated by twisting the hexagonal hub beneath the dial with pliers. 1 inch dial thermometerRange 0 degree Fahrenheit to 220 degree FahrenheitRed pointerShatterproof plastic lensStainless steel 5 inch stemExclusive Safe-T-Set recalibration featureStorage sleeve with built-in recalibration wrench
