ThermoWorks Thermapen ONE
Accurate to half a degree, says ThermoWorks, and backed for five years.
You cook meat a few nights a week and want a number you can trust right away.
You mostly cook on a smoker and want to follow the meat from the couch. That's a job for a wireless probe.
A reading in about one second
America's Test Kitchen still ranks it first among instant-read thermometers. In their trials it took 1.1 seconds on average and stayed within 0.07 degrees at 125°F, where other models drifted up to 2 degrees off. ThermoWorks rates it at ±0.5°F at cooking temperatures. Because it's so quick, checking a pork tenderloin in two or three places takes no longer than one reading with a slow thermometer.
The screen turns itself so the numbers are right side up, and the backlight comes on by itself in the dark. There's no power button. Pick it up and it turns on. It runs on one AAA battery and it's IP67 waterproof, so you can rinse the probe under the tap.
It comes in a few colors at the same price. I'd get the red.
Several of the newest reviews come from people replacing an older Thermapen. One whose Classic finally quit was glad to switch to a plain AAA battery, and a competition barbecue cook says he wouldn't show up to a cook-off without one. The one mild complaint comes from a longtime Mk4 owner (it lasted ten years, until a trip through the dishwasher) who finds the ONE a little wider, with a shorter probe.
- Hey Grill Hey found the battery runs down a little faster than in other ThermoWorks models.
