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.

  • Best Wireless Thermometer. The most accurate and reliable wireless thermometer we’ve tested so far, this model is a good option if you really hate wrangling probes and cables...

  • 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.

Don’t take our word for it. Here’s what others have to say.

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.

Reviews

RFX Wireless Probe is great

"Recently purchased the RFX Wireless Probe Starter Kit. I have cooked fish twice using the probes. The RFX is easy to set up and allows me to set temps in the app to alert me when I have different sizes of fish, yet allowing each to cook to the perfect temp. The RFX range and signal strength is excellent. I can monitor the cooking temps with my fish on the grill while I am in the kitchen getting the rest of the meal ready."

— Gordon S. (5/5)

Learning curve for sure, but

"Learning curve for sure, but once you get it you get it. You either need to buy the battery bank or get a Thermacell pack on Amazon with a straight dc to usb-c adapter and a dumb male to female dc cable. The fan will not spin unless it gets 12v. Your portable battery pack you already own won’t get the job done. Great product, great ecosystem. I won’t consider any other brand."

— Sean L. (5/5)

Second one I've bought

"I used a single RFX meat for a year or so, but finally broke down and bought a second one (I should've purchased the set of 4 in the first place). The RFX probes are the only ones that work flawlessly. I've tried every other major brand and a couple of obscure ones. None of them stay connected the way they should. When I use them correctly (I've goofed a couple times) the RFX work perfectly. Don't buy any other meat probe than the RFX."

— Neil P. (5/5)

I ruined a probe. . . they replaced it!

"I love RFX! No doubt about it. Works great, BUT the probes have one issue - don't expose them to too high of a temperature! I ruined a probe by (thoughtlessly) trying to use it in hot oil. The wired probe is fine, but the overheat kills the electronics. So only use the probe inserted into meat TO THE LINE. Now a plug for Thermoworks. Once we figured out what happened, they offered to replace the probe at a generous discount. Go Thermoworks!"

— Ray B. (5/5)

Perfect Tri Top

"Completed my first cook with the RFX, everything turned out great. I was very impressed by the accuracy and reliability of the system. I've only used it twice so far but everything worked perfectly. Wired probes are always a bit of a hassle, especially if you have multiple pieces of meat grilling at the same time. The wireless probes make it to look easier to maneuver things around on the grill without the worry over crossing lines. The app is a bit dated if I'm being honest. This is definitely the weakest point of the whole system. That said, it worked give, though it could be quite a bit more user friendly."

— christopher j. (5/5)

Wireless probe on RFX

"Hi, i have a wireless probe my wife got me at Christmas and i did a low and slow cook with a maximum temperature of 300F in my pellet grill. There were two probes in the meat and now one of the probes will only display one temperature reading. I do like the unit, i just hope they will last. i just bought another two probe set which is why i am getting this review as i do like them if they will work for me. Thanks"

— Ronald V. (5/5)

Only used it a couple

"Only used it a couple times so far but works great! Not a single drop out issue. Had 3 meaters that failed and this is so much more reliable. Could use improvement on the user interface to make it look better but everything is perfectly functional"

— Luke B. (5/5)

Almost Perfect

"Works flawlessly except Looses connectivity. when the protein your cooking requires being wrapped in aluminum foil. Work around Blindly Push probe through the foil into your protein …But if your protein requires precise probe placement to get an accurate reading of doneness (i. e. Brisket) you are at a disadvantage"

— ROBERT P. (4/5)

RFX System Works Great!

"I have used the RFX probes and gateway several times now and cross checked them against other thermometers. They are very accurate and work great with the app. They have helped me make sure my tomahawk, pork chops and other items turned out fantastic."

— Sam D. (5/5)

Great Device with Limitations

"The device works really well for large items, but because of the minimum immersion line it doesn't really work for smaller items such as filet mignon, burgers and fish. I will still find it useful for the large items but, for the price, wish it was more versatile."

— JAMES N. (4/5)

Q&A

Can the RFX probe be used in an oven. I'm assuming yes, but all the photos show it only be used for barbecuing.
Yes, RFX can be used in the oven! Just make sure the RFX MEAT probe is inserted to the minimum immersion line.
Are the probes Bluetooth yet. I’m at competition with no internet. I need them to operate just in my work space
Yes, RFX GATEWAY can now communicate with your phone via Wi-Fi or Bluetooth.
In the picture there is the RFX wireless probe and an air temp probe. Does the package contain both? And how do they work together?
Yes, the RFX Starter kit includes both. In the app, you will see both the RFX MEAT temperature and the temperature from the ambient probe through the RFX GATEWAY.
Can the App be used on a laptop computer?
When on your laptop, you'll log into ThermoWorks Cloud, which is the same information you find on the app.
Can proves go into dishwasher “JW” help me last nite with startup - excellent help
Yes, RFX™ Wireless probes are dishwasher safe. Just place them securely and you’re good to go.
