ONE. Second. Readings. Thermapen ONE almost moves at the speed of thought...allowing you to focus exclusively on the quality of your work. More Accurate With an improved accuracy spec of ± 0.5°F (± 0.3°C), you’ll know your lightning fast Thermapen ONE readings are always accurate, as well. Brighter Backlight The automatic backlight is brighter and the light sensor is more sensitive to changes in ambient lighting conditions. 5-Year Warranty The newly designed rugged, waterproof case features a 5-year warranty against defects. With a newly designed battery compartment for easier access to the user settings and all the amazing features you loved in the Thermapen Mk4—auto-rotating display, motion-sensing sleep and wake mode, waterproof to IP67, NIST-traceable calibration certificate—you'll need to get ONE for yourself to understand the power of sub-second performance.
