No touch measurement, just safe and hygienic: Built-in infrared temperature sensor, reads body temperature within 1.18 inches from the center of the forehead without physical contact. Tri-point sensors accuracy: An ultra-sensitive infrared sensor collects over 100 data points per second while distance and environmental sensors combine to account for other variables; ensuring maximum accuracy every time temperature is taken. Fast, simple, clear and quiet: The thermometer's intuitive single-button control design indicates the temperature in 1 second on a clear and bright extra-large LED display, even in total darkness. The silent vibration alert ensures there is no buzzing noise and no disturbance. Suitable for multi-scenarios and all ages: It is designed for all ages: ranging from babies and toddlers to the elderly. An ideal choice for hospitals, hotels, schools, and public institutions. Monitor your temperature with ease. With the non-contact forehead thermometer, measure the temperature of the whole family hygienically, painlessly, and with high accuracy. An ultra-sensitive infrared sensor that measures the infrared energy emitted by the forehead and collects more than 100 data points per second. A distance sensor ensures that measurements are taken no more than 3 cm from the forehead to avoid errors. An environmental temperature sensor that detects changes in ambient temperature in real time to reduce their impact and ensure measurement accuracy. All this with a single button and in just one second. No more worrying about cross-contamination and the spread of germs throughout the household. Our non-contact thermometer is safe and hygienic. A gentle vibration signals the end of the measurement. No shrill beep to wake your child when you monitor their temperature while they sleep. Unit of measurement: °C and °F.
