ThermoPro TP-511 Digital Candy Thermometer Reviewed And Rated

Share on:
ThermoPro TP-511

The ThermoPro TP-511 digital candy thermometer is designed to aid in candy making and frying. It features a long probe and a clip to attach the tool to the pot.

The head of the thermometer swivels to permit reading from any angle. The display is large and has a backlight that doubles as the temperature alarm. The user can set a temperature at which the backlight will begin to flash, alerting that the desired temp has been reached. There is no audible alarm, however. The unit will power down if left for two hours below 122°F or 50°C.

The unit is sealed against water entry and can be rinsed under running water. The test sample exhibited very good accuracy. Should it be necessary, the unit can be recalibrated in an ice water bath. It runs on a single AAA battery; no battery life estimates are made. Because of the intended use, it’s not meant to be a fast-reading thermometer, so don’t use it as a substitute for an instant-read thermometer.

The build quality is good, and it’s nice that it’s water-resistant. Contact information for the manufacturer includes a telephone number and e-mail address should tech support be necessary. The warranty is for one year.

Overall, this is a well-performing product at an attractive price so we awarded it a Gold Medal.

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.
