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.

The patented 360° self-rotating display can be used in any position, in either hand and is truly ambidextrous. The Thermapen One incorporates an intelligent backlit display sensing light levels, automatically turning 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, maximising battery life. 

The casing is washable and includes Biomaster Anti-Microbial Technology that reduces bacterial growth and the ergonomic rubber seal minimises 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. 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 indication are displayed, when applicable. Each Thermapen One is supplied with a FREE traceable certificate of calibration.
