ThermoWorks RFX Meat Mini launches

ThermoWorks announced the RFX Meat Mini on March 8, 2024. The new probe measures 2.6 inches from tip to base, a 10% reduction from the 2.9-inch full-size RFX Meat. The company claims the Mini retains the same four-sensor array and 0.1-degree accuracy as its predecessor.

Design and build

The Mini’s housing is a single-piece polymer block that meets IP69K standards. The manufacturer notes the probe can withstand immersion up to 1,000°F and survive a drop from 1.5 meters. The tip is a 0.5-inch diameter thermocouple, identical to the full-size model. The probe’s battery compartment is sealed; a removable AAA block powers the unit and lasts up to 48 hours on a full charge.

Connectivity and software

ThermoWorks retains the 433 MHz radio used by the RFX Gateway. The Mini pairs automatically when it enters the Gateway’s range. The Gateway then forwards data to the ThermoWorks app over Wi-Fi. The app displays real-time temperature, a countdown to target, and a history graph. The company does not list any firmware updates for the Mini, implying the probe uses the same firmware as the full-size version.

Pricing and bundles

Retailers list the Mini at $99. ThermoWorks offers a 20% discount when the probe is purchased with a Gateway or Starter Kit. The discount brings the price to $79.20. The company does not disclose MSRP for the Gateway, but the Starter Kit typically sells for $199.

Target market

The Mini targets cooks who need a probe for filet mignon, salmon, or other small cuts. The 2.6-inch immersion line allows the probe to fit inside a 3-inch thick steak without protruding. The probe’s small size also makes it easier to handle in tight grill spaces.

Competitive context

The RFX Meat Mini competes with other wireless probes such as the Meater Plus and the ThermoWorks Thermapen. The Meater Plus offers a 3-inch probe, while the Thermapen is a handheld device that requires a separate thermometer. The Mini’s 48-hour battery life and IP69K rating give it a durability edge over the Meater Plus, which has a 24-hour battery life.

Risks and caveats

ThermoWorks does not provide a warranty for the Mini beyond the standard one-year limited warranty. The probe’s small size may make it harder to clean, despite the IP69K rating. Users who rely on the probe for sous-vide cooking may find the 2.6-inch length insufficient for larger volumes.

What to watch next

ThermoWorks has not announced a firmware update schedule for the Mini. If the company releases a new firmware version, it could add features such as Bluetooth Low Energy or extended battery life. The company also has not disclosed plans to release a 3-inch probe variant.
