ThermoPro TP-19 Review

ThermoPro TP-19 Review
The ThermoPro TP-19 is a folding-type instant read food thermometer with a bright rotating display and can be rinsed under running water. The unit cannot be left in food while it is cooking.
Like other folding thermometers, the unit turns on when the probe is pulled away from the body. It will stay on for 90 seconds if undisturbed, then shut itself off. Picking up the unit will turn it back on if the probe is extended. The probe unfolds 180° but no farther, slightly limiting its functionality for a left-handed user. The two-position display will turn itself upside down for lefties, though. There is a "Lock" button that will capture the current temperature and display it for five seconds. There is another button on the back to change between Celsius and Fahrenheit. There is a magnet built into the back of the unit to affix it to a (cool) metallic surface.
Temperature accuracy is excellent. So is the speed of response - right up there with the best of them. If the unit's accuracy is suspect, the user can recalibrate it using an ice bath and following the instructions. The unit runs on a single AAA battery (supplied) that lives behind a sealed hatch on the back. I put the unit under running water in the kitchen sink with no degradation of performance.
The thermometer comes with a one-year limited warranty that is extended to three years upon product registration. The instruction manual has a phone number and an e-mail address should customer service be necessary. The instructions are in English and French.
Overall, this is a well-made unit with excellent performance, and should stand up well in the cooking environment.

3) Tell us everything we need to know to help such as the type of cooker and thermometer. Dial thermometers are often off by as much as 50°F so if you are not using a good digital thermometer we probably can't help you with time and temp questions. Please read this article about thermometers.
