This commercial oven thermometer lets you see at a glance if your oven is cooking at the temperature you set. The stainless steel oven safe thermometer has a thick glass lens that protects the face from oven heat and food spatters. A red pointer clearly indicates temperature readings from 100°F to 600°F in 5-degree increments, and the thermometer has a Celsius scale, too. The unit 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 rack. The NSF Listed thermometer is key in how to calibrate oven temperature more accurately.
