A Professional Thermometer

The Mk4 is a professional thermometer that measures temperatures over the range of -58.0 to 572.0°F (-49.9 to 299.9°C), with a high degree of accuracy (±0.7°F / ±0.4°C ) within 2-3 seconds. Thanks to its advanced thermocouple technology, which puts the sensor very close to the end of the probe tip, this unit can give you precise readings even in thin pieces of meat like ribs.

Besides this technology, this unit includes a number of useful and innovative features. It has a 360º self-rotating display that can be used in any position, in either hand. Hold it in any direction and the display automatically rotates right-side-up so you can read it in any position.

It also comes with an intelligent backlit display sensing light levels, automatically turning the backlight on/off in varying light conditions. For maximizing battery life, the Thermapen Mk4 comes with a motion-sensing sleep mode, that automatically turns the unit on/off when set down or picked up.

Great Build Quality

Another selling point of the Thermapen Mk4 is its build quality. The casing is washable and includes Biomaster Antimicrobial Technology that reduces bacterial growth. And as if this is not enough it’s also waterproof to IP66/67.

After start using this thermometer, we will notice that everything is built with a purpose. The Mk4 incorporates a reduced tip, that conveniently folds back through 180º into the side of the instrument when not in use. This feature is particularly useful when it comes to store the thermometer, or when you to travel with it, for example to a BBQ competition.

In terms of battery, this unit is powered by a single AAA battery, and accordingly, to the manufacturer it will last around 3000 hours in normal use, without the backlight.
