The ProTemp S1 is designed to fit almost all grills and smokers on the market. Simply remove your existing gauge thermometer and replace it with the S1, or drill a new hole if needed(do not drill ceramic).
There are 4 different variants of the ProTemp S1.
Universal Version: This model has a base stem diameter of 7.8 mm (0.3 inches) and is compatible with most grills and smokers, including Weber, Kamado Joe (except Big Green Egg), drum, offset, and kettle grills. It’s ideal if your grill’s gauge hole is approximately 0.3 inches or larger.
BGE Version: Designed specifically for Big Green Egg grills or other grills with smaller gauge holes like Primo Oval XL, this version has a thinner base stem diameter of 4.1 mm (0.16 inches). It’s perfect for Big Green Egg, Primo Oval XL, or similar grills with smaller ports (For the Primo XL series, since the thermometer hole diameter may vary depending on the production year, it is recommended to measure the diameter of the thermometer hole before purchasing the ProTemp S1).
5.5” Special Edition: Its base stem diameter is the same as the Universal Version, at 7.8 mm (0.3 inches), but its stem length is longer, at 5.5 inches, making it suitable for devices where the thermometer is farther from the food, like Old Country Gravity Fed smoker.
1.5″ Short Stem Edition: Retaining the same base stem diameter as the Universal Version, at 7.8 mm (0.3 inches). This model features a shorter 1.5-inch stem. The reduced length ensures better compatibility with grills requiring limited internal clearance, preventing interference with lid operation. It’s particularly well-suited for certain gas grills, such as the Weber Genesis and Napoleon Prestige PRO series.
We recommend measuring the gauge hole on your grill to ensure the perfect fit before choosing a version.
