Sturdily made of commercial-quality stainless steel, this Pyrex Accessories Professional series oven thermometer measures oven temperatures up to 600 degrees F. With a wide bottom, it sits anywhere in the oven, or you can use the handy loop on top to hang it from your oven rack. The dial has large, easy-to-read numbers in 50-degree increments from 100 to 600 degrees. This thermometer works in both conventional or convection ovens, has a lifetime warranty, and must be hand washed. --Doree Armstrong
