The ThermoPro TP-01A is a small, light-weight and inexpensive hand-held instant read thermometer that exhibits good accuracy and quick response times. It cannot be left in food in a cooker.
The unit has a long probe with a narrow tip that allows it to respond quickly to changes in temperature. It is turned on by pressing a button that doubles as the ºF/ºC selector. There is a second button that allows you to capture and hold the reading, and a third button that activates the blue backlight. The display is on the small side but readily legible. There is a loop at the top that can be used to attach a lanyard or hang the instrument on a hook.
This thermometer operates on two AG13 button batteries instead of the more readily-available AAAs. The battery life is not specified in the user instructions. The housing is not sealed against the ingress of moisture, making it vulnerable to damage in the cooking environment. The sample we tested died shortly after testing, displaying only “LL.L” despite being at room temperature. (This reading normally would indicate that the temperature was below the range for which it was designed.)
Aside from the mortality failure, the thermometer was quicker than all but the best instant reads and its accuracy was good. The build quality leaves something to be desired, but it costs only $8.99, so you get what you pay for. The product comes with clear instructions. The manufacturer’s contact info includes an e-mail address, a website URL, and a telephone number. It is covered by a one-year limited warranty.
We’ll give it a Bronze Medal for decent performance at a low price, despite its marginal construction.
