MORE INFO About Thermapen ONE

The NEW Thermapen One thermometer is the latest model of the UK’s number one-selling food thermometer, Thermapen. Measuring temperature over the range of -49.9 to 299.9 °C as well as used by hundreds of thousands of discerning cooks worldwide. Moreover, it offers a combination of speed, accuracy, and convenience of use. The new Thermapen One uses advanced technology and includes a number of innovative features illustrated below.


The Thermapen One is fully configurable using buttons in the battery compartment. Here you can choose to lock the display position, disable auto-sleep mode, choose °C or °F scales, and select 1° or 0.1° resolution.
Additionally, the patented 360° self-rotating display enables use in any position, in either hand, and is truly ambidextrous. Since the Thermapen ONE Thermometer incorporates an intelligent backlit display sensing light levels, it automatically turns the backlight on/off in varying light conditions. The motion-sensing sleep mode with user-changeable time delay automatically turns the Thermapen on/off when set down or picked up, maximizing battery life.
The casing is washable and includes Biomaster Anti-Microbial Technology, thus it reduces bacterial growth. Furthermore, the ergonomic rubber seal minimizes the risk of the ingress of water, dust, or food.
As well as being waterproof to IP67, it is 'probably' the fastest reading contact thermometer on the market today. What's more, the true temperature of a product can be tested in just one second. The Thermapen One incorporates a reduced tip, stainless steel, food penetration probe (Ø3.3 x 110 mm) that conveniently folds back through 180° into the side of the instrument when not in use.
The Thermapen One is powered by a single AAA battery with a life expectancy of 2000 hours in normal use, without the backlight. Both low battery (icon) and open circuit indications are displayed, when applicable. Each Thermapen One is supplied with a FREE traceable certificate of calibration.

Not sure what I’d do without it

The best tool I’ve got. And it’s survived an absolute beating and still works perfectly

Stephen Duncan
Essential tool

What can you say about the Thermapen ONE.
Apart from get one you need it for accurate temp measurement now I have it will never be without it

Esses Smoke bois
must have

love my thermapen! I won a thermopen professional from a giveaway from prosmoke on instagram and honestly it is the best tool for the back yard bbqer. its so accurate and reliable and great that it is waterproof to a certain extent as i have left mine outside after a cook on a number of occasions. the price may seem a little hefty but youll spend more money on cheap thermometers instead on just buying one expensive one!

its the very first tool i recommend people getting into barbeque get themselves

Tom Doherty

Pro smoke bringing all the tools! Great service time and time again! Cheers guys!
