Designed for professional kitchens and food service environments, RFX delivers continuous remote temperature monitoring across extended cooks. Wireless probes track internal temperatures in real time so teams can verify doneness, maintain consistency, and protect food safety without interrupting service. Built on patent-pending sub-GHz radio frequency technology, RFX maintains a stable probe-to-gateway connection across kitchens, smokers, ovens, and production spaces—without the dropouts common to Bluetooth®.

Each gateway supports 50+ probes and sends continuous data to the ThermoWorks app and cloud for visibility across multiple cooks simultaneously. Four independently calibrated sensors deliver ±0.9°F accuracy across critical cooking ranges, while the RFX MEAT™ probe withstands external heat up to 1,000°F and runs 50+ hours on a single charge. Whether monitoring briskets in a BBQ pit, verifying pasteurization in cook-chill systems, or tracking temperatures through conveyor ovens, RFX provides reliable, real-time data to support operational efficiency, consistency, and food safety compliance.

  • Stable Long-Range Wireless Signal: Patent-pending sub-GHz RF maintains a dependable probe-to-gateway connection across kitchens, smokers, and large production spaces.
  • Reliable Where Bluetooth Falls Short: Sub-GHz RF penetrates walls, ovens, and equipment where Bluetooth probes often lose signal.
  • Follow Temperatures Across the Entire Cook: Four independently calibrated internal sensors monitor temperature changes along the probe length for clearer insight into doneness and product consistency.
  • Verify Critical Control Points: ±0.9°F accuracy supports HACCP programs and helps confirm critical cooking and pasteurization temperatures.
  • Built for High-Heat Cooking Environments: Probe withstands external temperatures up to 1,000°F for grills, rotisseries, smokers, and high-temperature ovens.
  • Designed for Extended Production Cooks: 50+ hours of battery life supports overnight smoking, large batch cooking, and long production runs.

As Seen On...

  • Best Overall Wireless Meat Thermometer. I walked about 430 feet away from the backyard to the end of the cul-de-sac, holding the base station, and it was still connected to the probe sitting in a sponge, within a cast-iron Dutch oven, resting in a steel smoker.

  • Setup was easy... I just connected the Gateway to my WiFi and simply tapped a probe against the side of the Gateway. It immediately popped up on the app, and I was ready to get cooking.

  • Yes, you read that right. This is a wireless thermometer that can operate in high heat environments like pizza ovens and searing stations.

  • The best leave-in meat thermometer. This wireless meat thermometer had the most reliable signal of any we tested, and it comes from the makers of our longtime favorite instant-read thermometer.

  • You can deep fry, roast, sous vide, and grill with this wireless thermometer from ThermoWorks.

  • This wireless meat thermometer is a game-changer when it comes to range and sleek design if you are in the market for a wireless meat thermometer probe.

  • The ThermoWorks RFX Wireless Probe Starter Kit is a game-changer in temperature probes. This is the first wireless probe that gave me zero problems.

  • The ThermoWorks RFX Wireless Probe Starter Kit is a solution for anyone trying to cook...I've been able to test out the ThermoWorks RFX Wireless Probe Starter Kit and have been really impressed with its precision.

The RFX system abandons unreliable Bluetooth in favor of our patent-pending Sub-1 GHz radio frequency. Engineered for uncompromising durability, this professional-grade technology effortlessly pushes signals through thick steel smokers, heavy dutch ovens, and commercial oven walls. By prioritizing signal density over novelty, RFX delivers the most stable, uninterrupted wireless thermal data available for precision cooking.
The RFX Meat Probe captures internal temperatures and transmits them via our patent-pending Sub-1 GHz RF technology directly to the RFX Gateway. Acting as a powerful bridge, the gateway instantly processes that raw thermal data and pushes it over Wi-Fi or Bluetooth to the ThermoWorks App, ensuring your cooks are monitored with exacting, continuous reliability.
The RFX probe transmits temperature data up to a commanding 1,500 feet line-of-sight directly to the gateway. Once the gateway connects to your local Wi-Fi network, your monitoring range becomes infinite. This robust architecture ensures you can track your cooks with absolute certainty from anywhere in the world via the cloud-connected ThermoWorks App.
Absolutely. The RFX ecosystem is engineered with a grounded, long-term vision, designed to grow alongside your culinary needs. The current RFX Gateway acts as the central hub for a future-proof mesh network, preparing your setup to seamlessly integrate a growing lineup of specialized ThermoWorks probes, and sensors without forced obsolescence.
Traditional Bluetooth thermometers hit a strict hardware bottleneck, capping out at just four connections. By utilizing our proprietary Sub-1 GHz RF technology, the RFX Gateway bypasses these consumer limitations, effortlessly managing up to 50 independent probes simultaneously. This purpose-driven capability allows professional kitchens and pitmasters to scale operations with absolute confidence.
