ThermoWorks BlueTherm Probe Review

ThermoWorks BlueTherm Probe Review

The BlueTherm probe must be used with a Bluetooth device to measure and record temperatures. It can be used with a desktop/laptop that has Bluetooth capability, or a smart device such as an Android or Apple phone or tablet. Software to control and read the device is free and downloadable from Thermoworks or your device’s app store. Don’t plan on leaving this probe in food while it is cooking.

The probe has a rechargeable battery that is refreshed via a USB port. It can be fully charged in 2 hours and will run for 36 hours on one charge. Range is claimed to be 65 feet. There is no display on the unit other than an LED that indicated Bluetooth connectivity. It is well-sealed and should be easy to clean. The USB port has a silicone plug to keep moisture and dirt out.

The accuracy and speed of response are excellent. Construction is industrial-strength. While this unit can be used by a home cook, the lack of a direct readout makes this an unusual choice unless data logging is required. For sheer geekiness, it would be tough to beat, but I would probably prefer a probe I could read without having to connect my smart phone. Because this is a hand-held, instant-read thermometer, the remote connectivity isn’t really a big asset. Unless you’re trying to score points at a Mensa cookout, I’d get two Thermapens and have money left over.

We give it a Silver medal for construction, accuracy, speed of response and pure geekiness.

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.
