The newest instant-read thermometer by ThermoWorks is the best we’ve tested yet. It has all the features we loved in our previous favorite: a large, grippy handle; a rotating screen with large, highly legible numbers; and a backlight that goes on when viewing conditions are dim. It’s waterproof to a water depth of 39 inches for 30 minutes, it goes to sleep when not in use, and the display wakes up automatically when you pick up the entire unit. The ONE improves on its predecessor, though: As its name indicates, it takes just 1 second to measure a temperature. The backlight is brighter, and you can now use the thermometer when cooking on induction burners—the engineers at ThermoWorks have taken measures to eliminate the electromagnetic interference that sometimes occurs when you use digital thermometers with induction cooktops.
