The RA600 infrared ear thermometer measures the infrared heat generated by the eardrum and surrounding tissue. The ear accurately reflects the core body temperature because the eardrum shares the blood supply with the temperature control center in the brain. When core body temperature rises, it can be quickly detectable in the ear.The Continuous Scanning Mode in the thermometer views the entire ear canal and looks for the highest temperature that can be detected. Simply press and hold the start button for 3 seconds, gently rotate the probe inside the ear canal in a circular manner and the most accurate reading will appear.This thermometer comes with a smart technology that highlights low battery life and has a quick auto shut off mode.
