Tom’s Guide Verdict

The Thermapen ONE by ThermoWorks is a great gadget in the kitchen.

This no-nonsense thermometer can be inserted into foods for an instant digital result.

Its easy to use, but you better be hands-on, unlike when using a leave-in thermometer.

Here’s how it went.

The Thermapen One is ready to use whenever you need it.

Then, once the probe is pulled out, it becomes active.

When the light level reaches a certain point, the backlight comes on to illuminate the reading.

you might test it by placing your thumb over the sensor and shielding the display with your other hand.

The casing is solid and comes in a range of bright color-popping colors directly from ThermoWorks.

However, if you prefer a more subtle tone, its available in White, Black, and Charcoal.

How does the probe work?

The company also claims that this sets the Themapen ONE above its competitors.

Customizing the tweaks

The one downside I found with the Thermopen ONE is accessing the customization buttons is difficult.

User guides

The thermometer comes with operating instructions and a comprehensive user guide to get you up and running.

They are certainly worth reading to ensure you get the most out of using the Thermapen ONE.

It’s worth keeping the guide close to hand for the temperature references, if nothing else.

ThermoWorks states that the final resting temperature should be between 31.5 and 32.5F (or -0.3C and 0.3C).

Thermapen ONE: Performance

This thermometer comes with its own Certificate of Calibration.

What does this mean?

Its been signed by the testing technician and includes the date of testing and the product serial number.

Receiving the certificate gave me reassurance that the thermometer is highly accurate.

You wont get a reminder that you’re gonna wanna check your meat.

However, you do have to be hands-on with this process.

Although this is higher than the desired final temperature, it is still perfectly acceptable without drying the meat.

And while testing the Thermapen ONE, I used theNinjaProChef wireless thermometer alongside it.

As before, the Thermapen ONE gave me a quick digital reading within one second.

It can be cleaned in exactly the same way as the probe.

Its also highly accurate and super fast.

I can see the benefit of using an instant-read thermometer, along with one that is wireless.

Its also easy to clean and store, and the guidance that comes with the product is helpful.

But, where it particularly excels is in testing liquids.

I can see that it will come in handy when testing the temperature of homemade jam.

It can also monitor water temperature when you require a poach, simmer, slow or rolling boil.

In this department it can do so much more than a leave-in thermometer.

One disadvantage is the price, as there are cheaper instant-read thermometers available.

Although, what you pay out you get back in accuracy, which is the product’s USP.
