Overview
Tel-Tru's BQ300 is a 3-inch glow-dial barbecue thermometer made from 304 stainless steel, with a 4-inch blunt-tip stem and a 100 to 500 degree F range. It threads in as 1/2 inch NPT and is built for permanent mounting in a smoker, pit or grill lid.
- 304 stainless steel construction
- 1/2 inch NPT threaded connection
- 3 inch glow dial with zones
- 4 inch blunt-tip stem
Who it's for
Good for smoker and pit owners installing a permanent dial thermometer into a 7/8 inch hole. Not a fit for grills whose factory hole is smaller, such as the Weber Spirit line's 3/8 inch opening, unless you're willing to drill a new one.
Pros and cons
- Accuracy confirmed by multiple owners against probes and boiling water
- Glow dial stays readable in the dark
- Stainless steel build holds up outdoors
- Installation kit sold separately and pricier through the listing than direct from Tel-Tru
- Does not fit every grill's stock hole size
- A couple of owners found the element could loosen after mounting
