TempPro TP20 Wireless Meat Thermometer Review: Budget Pick Serious Eats Still Recommends

Product Overview

The TP20 is a traditional leave-in probe thermometer: wired probes sit inside the food during cooking, transmitting temperatures wirelessly to a handheld receiver via radio frequency (RF) signal — not Bluetooth or Wi-Fi. The brand was called ThermoPro until a rename to TempPro; the ASIN and product are unchanged.

The transmitter clips onto your grill; the receiver stays with you — in your pocket, on the kitchen counter, or clipped to a belt. No smartphone is involved. Both probe temperatures display simultaneously on the receiver.

Performance & Real-World Use

The RF signal is a deliberate choice, and reviewers consistently praise it. RF doesn't depend on your phone's Bluetooth range or your Wi-Fi router's reach, so it maintains a stable connection at backyard distances without dropouts. FoodFireFriends and BarbecueFA both confirmed reliable operation at the full 300-foot real-world range, which is adequate for virtually any home outdoor cooking setup.

Setup is genuinely fast. There's no app to download, no account to create, no pairing sequence. You insert batteries, stick the probes, and start cooking. Bob Vila's testing team called it "one of the easiest to set up" among probe thermometers they've evaluated. The nine USDA-standard preset temperatures for beef, pork, chicken, and more mean you don't need to look anything up before a first cook.

Accuracy is adequate but not exceptional. AmazingRibs.com, which tests thermometers with calibrated reference instruments, found the TP20's readings running 2–4°F above actual temperatures across a range of test points. That figure falls within the stated ±1.8°F spec at its widest, and it's unlikely to cause a cooking failure. But it means the TP20 is not the right tool if precision down to a single degree matters — it's a get-it-done workhorse, not a precision instrument.

The dual-probe layout is where this thermometer justifies its existence. One probe monitors the internal temperature of the meat; the second can be positioned near (but not touching) the grill grates to track ambient cooking temperature. Running a smoke at 225°F while your brisket climbs through the stall? Both numbers are on the receiver screen simultaneously. That combination — and the ability to set high/low alarms on both channels — is genuinely useful during long smoking sessions where babysitting the thermometer gets old.

The probes struggle with small or thin cuts. Their straight, 8-inch length is designed for thick roasts and whole birds. Using them on burgers, chicken wings, or sausages requires awkward angled insertion, and the probe cable can drape across active grill grates if you're not careful. Bob Vila specifically noted poor results with thin and bone-in cuts.
