What it does
A pocket sized folding probe thermometer with a backlit screen and a magnet on the back, now listed by the maker as the TempSwift PLUS TP03B.
- Folding probe tucks into the body for storage
- Magnet on the back holds it to the fridge or grill
- Backlight for reading in low light
- Switches between Fahrenheit and Celsius
- Runs on a common AAA battery
A strong budget choice for home cooks who want quick, accurate spot checks on meat, oil or candy. The trade-offs are build details: the hinge and button feel flimsy, the screen does not rotate, it cannot be recalibrated, and it is not waterproof.
