Your old thermometer's rusted through or the dial's stuck at 120 and you're guessing whether that steak's done. This JAYCAR dial-type unit drops into any BBQ where one's missing or broken. The 75mm stainless steel bezel is easy to read from across the yard, and the dial runs both Fahrenheit and Celsius so you don't have to do the conversion mid-cook. It needs a 9.5mm (3/8") hole in your lid — standard for most grills. No batteries to replace, no digital screen that dies in the sun. Just a solid mechanical read. Backed by a 1 year warranty.
