ThermoWorks' RFX Meat wireless probe uses radio waves instead of Bluetooth to monitor food on the grill
A more reliable connection and longer range are both on the menu.
Wireless food probes are some the best grilling gear for keeping tabs on meat and other items while cooking. You don't have to dodge cords when you're flipping a steak or trying to wrap a brisket. Several companies make these, Traeger-owned Meater being one example, but existing products rely solely on Bluetooth and have ambient temperature sensors that may not be the most accurate. ThermoWorks, the company that's known for its Thermapen instant-read thermometers, has officially announced its take on the wireless meat probe: the RFX Meat.
Like ThermoWorks' more robust grill and smoker temperature-tracking devices, the RFX Meat uses radio technology to transmit data rather than Bluetooth. The company explains that its "patent-pending sub-GHz RFX wireless technology" provides a more reliable connection with up to 2,132 feet of direct line of sight range. When placed inside a grill or smoker, ThermoWorks promises up to 659 feet of range. Similar to the competition, the RFX Meat has four internal sensors that provide an accurate measure of food temps with 0.9-degree accuracy between 14 and 212 degrees Fahrenheit. This probe is also IP69K rated, so it's safe to use for deep frying and sous vide. Plus, it can withstand temperatures of up 1,000 degrees Fahrenheit, which makes it well-suited for high-heat searing, and you can stick in in the dishwasher when you're done.
Since the RFX Meat utilizes radio frequency and not Bluetooth, you'll need a RFX Gateway receiver to use it. This small device sends cooking data to ThermoWorks Cloud when it's connected to WiFi, or it can be used offline with your phone via Bluetooth. Either way, you get timely updates on your phone to keep tabs on meat and other foods. And when the RFX Gateway is connected to WiFi, you can monitor what's on the grill or smoker from anywhere. The RFX Gateway is also capable of handling readings for up to 70 RFX Meat probes at once.
Most of these wireless probes come with a charging dock that doubles as a Bluetooth transmitter. RFX Meat resides in one of these (minus the Bluetooth), and ThermoWorks says you can get over 50 hours of use with a 10-minute charge. The dock uses a single AAA battery which should be enough for over 175 full charges, according to the company.
One thing the RFX Meat doesn't have is a built-in ambient temperature sensor. Meater's products, for example, have one situated at the far end of its wireless probes. But, ThermoWorks argues this component doesn't provide accurate readings. Due to the fact that it's close to cold meat at the start or in an evaporative cooling zone around food, a built-in ambient temperature sensor can't accurately keep tabs on the grill, according to the company. So, ThermoWorks devised a solution that uses a wired Pro-Series Air Probe from its other products that plugs into the RFX Gateway. Since this probe is only monitoring grill or smoker temps and can be placed out of the way, it's not as essential that it be wireless.
The RFX Meat starter kit is available for preorder today for $159. That price includes the RFX Meat probe, the RFX Gateway and a Pro-Series Air Probe. The same bundle with four RFX Meat probes is $349 and individual probes are $89. You can also purchase the RFX Gateway for $79, which comes with a Pro-Series Air Probe. ThermoWorks says it will start shipping the grilling devices on September 10th.
