Break free from spotty Bluetooth®. RFX™ by ThermoWorks is the only wireless meat thermometer you can actually rely on. Astonishingly stable, powerful, and long-range, our patent-pending radio frequency technology makes it easier than ever to monitor that brisket in real-time, from anywhere.
Everything you need to get started: RFX GATEWAY™ (receiver), RFX MEAT™ (wireless probe), Pro-Series® Air Probe (ambient temperature), grate clip, charging block, power adapter, USB cable, and probe rings.
How RFX stacks up
Move freely around your home, yard, or business.
When unobstructed and in direct line of sight, our signal reaches up to 1,500 ft between RFX MEAT and RFX GATEWAY. (That’s over 1,000 ft further than our closest Bluetooth competitor.)
The secret behind our superior signal
Bluetooth operates at a 2.4 GHz frequency, which means more signal peaks per second. Higher frequency signals experience greater attenuation, or loss of strength, when encountering obstacles like smoker walls. That's because shorter wavelengths are more easily absorbed.
The patent-pending sub-GHz wireless technology of RFX operates at a much lower frequency, 433 MHz, which translates to fewer signal peaks per second (longer wavelengths) and significantly better penetration through barriers. This lower frequency allows RFX to blast through thick metal smokers, home walls, and other robust obstacles, ensuring a strong, reliable connection no matter where you are. Stay truly connected with RFX.
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.

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.
