Perfect Temperature Every Time

This Ruby Grill Thermostat is a game-changer! I used to guess temperatures, but now my steaks are perfectly medium-rare every single time. It was super easy to install on my Sunstone grill, and the reading is always spot on.

Eli O.★★★★★June 29, 2024
Essential for Serious Grillers

As a BBQ enthusiast, precision is everything. The R-Tmeter provides accurate temperature readings, which is crucial for low-and-slow cooking or searing. It feels really well-built and has held up great through several grilling sessions.

Does the Job, But Nothing Special

The Ruby Grill Thermostat works as advertised, giving me a temperature reading. However, for the price, I expected it to feel a bit more premium or have some unique features. It's a basic gauge that gets the job done, but it's not a standout product.

Julian G.★★★★☆October 18, 2011
Reliable and Easy to Read

I'm really happy with this thermostat. The numbers are clear and easy to read, even when the grill is hot and smoky. It's a solid, reliable addition to my Sunstone outdoor kitchen setup, ensuring my food cooks consistently.

Eduardo Y.★★★★★July 18, 2013
Couldn't Grill Without It Now!

Wow, this R-Tmeter has completely elevated my grilling game! No more burnt edges or undercooked centers. The accuracy is fantastic, and it feels incredibly durable, like it's built to last. Highly recommend for any serious griller!

Q
Will this Ruby Grill Thermostat - R-Tmeter work with my older Ruby 'Emerald' series gas grill, or is it only for newer models?Asked by Sunstone Support Team
A
The Ruby Grill Thermostat - R-Tmeter is designed for broad compatibility across Ruby Gas Grill models, including many of the older 'Emerald' series. As long as your grill lid has a standard thermometer port or enough flat surface to drill a new one, this thermostat should fit perfectly.
