Easily check the temperature of your reach-in or walk-in refrigerators and freezers with the 2-1/2” dial on this commercial refrigerator/freezer thermometer. The color-marked temperature scale helps you maintain food-safe conditions and helps staff learn how to read a refrigerator freezer thermometer correctly. With a range measuring from -20°F to 80°F (-30° to 30° Celsius) accurate to within +/- 2°F, the color markings clearly show what temperature a walk-in freezer should be, as well as safe refrigerated temperatures. The stainless steel thermometer has a base for setting it on a sheet pan or solid shelf, and has an integrated stainless steel clip on top which you can use to hang it on a wire shelf.
