Your oven dial is a suggestion. This one is a fact-checker. Hang it from a rack or stand it on one and you finally know what the cavity is actually doing, which is how cakes rise on schedule and roasts stop being a negotiation. The oversized face uses high-contrast color zones you can read through a closed oven door, and the stainless steel body with its glass lens and red pointer stays legible after years of heat. Extra-large 3" dial with high-contrast color zones, readable through an oven door Stainless steel construction with a glass lens and red pointer Two-way mount: hang from an oven rack or stand on the rack NSF certified to commercial kitchen standards Limited warranty included 7" x 5" x 1.5" Hand wash Will be hot after use, so use oven mitts From Taylor, the precision-measurement brand since 1851
