ThermoWorks RFX™ Wireless Probe Starter Kit: 4 Probe

Break free from spotty Bluetooth®. RFX™ by ThermoWorks is the only wireless meat thermometer setup 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.

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.
