If you’ve ever cut into a steak too early or watched a brisket overshoot its mark, you know the difference a good thermometer makes. Two of the best in the game come from ThermoPro—the TP19 and the TP622 Lightning Read. Both are fast, waterproof, and built for serious cooks, but they’re not identical. One focuses on rugged simplicity, the other on next-level speed and accuracy. Let’s break down the difference so you can decide which one belongs next to your grill.

“Side-by-side comparison of ThermoPro TP19 and TP622 Lightning instant-read meat thermometers showing design and feature differences on a wooden background. Branded Smoke and Ride Official.”

The TP19: Rugged, Reliable, and Built to Last

The TP19 is ThermoPro’s everyday workhorse. It reads temperatures in 2–3 seconds with ±0.9°F accuracy, and the folding probe makes it compact enough to slip in your apron pocket. It’s IP65 waterproof, has a rotating backlit display, and is tough enough to handle life at the grill or smoker.
If you want a solid, dependable thermometer that’s fast, easy to read, and won’t quit on you—this is it.


The TP622 Lightning Read: Speed and Precision Combined

The TP622 Lightning Read takes things up a notch with a 1-second thermocouple sensor. It’s built for people who want instant, lab-grade readings with zero guesswork. The display auto-rotates, it wakes with motion, and it’s also waterproof—so cleaning it after a long cook is simple.
This one’s for pitmasters and detail-oriented cooks who demand precision.


Bottom Line

Here’s the deal:

  • Choose the TP19 if you want rugged reliability and solid performance.
  • Choose the TP622 if you want the fastest, most accurate readout available.

Both are major upgrades from guessing by feel—and both belong in your BBQ setup.
