News: Thermapen One Accurately Reads Temperatures in 1 Second!


The Thermapen ONE takes only 1 second for an accurate temperature check and is used by professional kitchens and pharma testing labs world wide. Made by ThermoWorks, each product is tested and verified for accuracy via NIST traceable calibration certificate. Temperature tolerance ranges from -58.0 to 572.0°F (-49.9 to 299.9°C).

The brings temperature checks to the next level in speed and accuracy. While it does work well checking food and beverage temps, I wonder how well it can deal with checking body temperature (say, under your tongue?)

This product comes with a 5 year warranty, is fully waterproof, has anti-microbial protection and lasts 2,000 hours on 1 AAA battery. Retails for US $105.
