ThermoWorks Therma K Plus with 313-158 Probe Review

The ThermoWorks Therma K Plus Kit is an expensive thermometer that exhibits superb accuracy and very rapid response times. The readout cannot be left in the oven/grill while cooking, but cabled probes can, making this a versatile unit that can act as a rapid-read hand-held or an in-food/in-cooker thermometer.

The thermometer can accept any K-type thermocouple probe. The thermometer’s inherent temperature range is –148 to 2501ºF (-100 to 1372ºC), but with the kit probe, the temperature range is a more suitable -58 to 482ºF (-50 to 250ºC). Other probes can extend the range considerably, but our focus here is on food temperature measurements. The unit does not have a water-resistant rating, but otherwise it has all the features one might want: min/max functions, a hold button, a backlight and F/C flexibility. The accuracy is right-on, and this probe reacts almost instantly, going from ice water to boiling water in about 4 seconds. The battery life is so long that you might never need to change them.

The manufacturer’s contact info, including address, telephone number, website and e-mail, is found on the instruction sheet. The thermometer is covered by a 1 year warranty. A certificate of calibration is included.

While this thermometer isn’t cheap, it is well made and performs with the best of them. For these reasons, we give 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.
