Ranked #2 in Best Meat Thermometers

ThermoWorks RFX

4.5

$299

The ThermoWorks RFX Wireless Meat Probe Thermometer offers a significant upgrade over Bluetooth competitors like Meater with its stable WiFi connection and extended range. Reviewers praised its accuracy, ease of setup, and ability to track temperatures up to 1,000°F. Serious Eats reviewer Grace Kelly found it reliable for smoking and roasting, while Vindulge's Sean Martin highlighted its extensive range and precision. However, both reviewers noted the app's navigation issues and slower probe response times compared to instant-read thermometers. This thermometer is ideal for serious grillers and smokers who need reliable long-range monitoring but may not suit those prioritizing app ease-of-use or ultra-fast response times.

Strengths

— Impressive signal range with stable WiFi connection that doesn't drop during cooking
— Accurate temperature readings confirmed through ice bath and sous vide tests
— Easy setup process requiring only WiFi connection and tapping probe to Gateway

Watch-outs

— App navigation can be difficult despite being mostly intuitive

How they stack up

ThermoWorks RFX

The ThermoWorks RFX excels in wireless monitoring with its stable WiFi connection and 500-foot range, surpassing the ThermoPro TP20's radio frequency and MEATER Pro's Bluetooth range. However, it's slower to respond than the instant-read thermometers like the Thermapen One and ThermoPop 2, taking about 22 seconds to reach 135°F. While the MEATER Pro offers better temperature resistance, the RFX provides a more stable connection and easier setup process, making it ideal for long cooking sessions where reliability is key.

ThermoWorks ThermoPop 2

The ThermoWorks ThermoPop 2 offers excellent value at $35, but it falls short of the Thermapen One's one-second read time and advanced features like motion-sensing sleep/wake modes. While it matches the Lavatools Javelin Pro Duo in terms of read speed and backlit display, the ThermoPop 2 lacks the intelligent stabilization feature and has a longer pocket clip that risks damage. Compared to the ThermoPro TP20, it provides better accuracy and a larger display, though it's more expensive and requires a button press to turn on.
