Nothing Works like ThermoWorks

Accuracy in every sensor
Roast, smoke, grill, and fry meats to restaurant-level perfection. Four hidden probe sensors are independently calibrated to find the true thermal center of your cook—and deliver ±0.9°F accuracy between 14 and 212ºF.

Precision you can trace
Each RFX MEAT probe comes with a digital certificate of calibration to certify that your instrument has been tested against international laboratory standards, including those set by the National Institute of Standards and Technology (NIST).

Ambient temperatures you can trust
Competitors’ built-in ambient sensors give inaccurate readings as cold meat acts as a heat sink, pulling heat from the metal probe and skewing the measurement of the ambient sensor by 75°F or more. Even if these sensors were accurate, they're placed in an evaporative cooling zone around the meat. This means your ambient sensor is not reading the accurate temperature of your cooker. Our Pro-Series® Air Probe plugs directly into RFX GATEWAY for precise placement and true ambient temperature measurements.

Multi-device management for businesses
RFX GATEWAY handles 50+ wireless RFX MEAT probes simultaneously, ideal for professional kitchens and large-scale operations. We’ve future-proofed RFX: Your gateway is also compatible with a whole suite of forthcoming ThermoWorks RFX products.

What the pros are saying

“I’ve been waiting two years for this. RFX will not only supplant the existing products but create a new category of reliability that doesn’t really exist.”
—Jeremy Yoder, culinary mastermind behind the “Mad Scientist BBQ” YouTube channel

“Now that’s technology you can count on.”
—Tuffy Stone, legendary pitmaster, restaurateur, and BBQ Hall of Famer

How RFX works

Communication flexibility for every cooking scenario.

1. RFX MEAT connects to RFX GATEWAY via patent-pending sub-GHz RFX wireless technology.
2. When connected to Wi-Fi, RFX GATEWAY sends data to our mobile app via ThermoWorks Cloud. Or, cook offline with a direct gateway-to-smartphone Bluetooth connection. (Offline mode coming soon)

Go further with ThermoWorks App + Cloud

Supervise in real-time:
Track your cook from anywhere, set crucial alerts, and instantly view cloud data in our mobile app.

Access powerful data tools:
Monitor temperature highs and lows, visualize data with graphs, and make informed adjustments using the cloud.

Connect devices securely:
Lock any device to your cloud account to protect data and prevent accidentally connecting to your neighbor’s gateway.

Scale up seamlessly:
Upgrade features with a paid Cloud Pro account — required for 11+ devices. (RFX probes and gateways count as individual devices).
