1. Accurate measurement: The built-in intelligent thermopile sensor can measure temperature by accurately identifying the surface of the human body. This product supports contactless measurement, which greatly improves safety. 2. Easy to use and easy to read: Aim at the center of the forehead, quickly measure 1 second, accurate to 0.1. Large LED screen, high brightness fonts are convenient for the elderly to watch. 3. Higher precision: increase distance, ambient temperature and ambient temperature compensation sensor. Wearing smart chip, distance sensor, ambient temperature sensor, temperature compensation sensor, such as standby, you can measure the ambient temperature in real time. 4. Easy to use: quick start, no delay, no need to wait, it can be directly used as a thermometer after connecting to the mobile power supply for the second speed measurement, contactless. 5. Compact: Instead of the traditional thermometer, it is lighter, only the size of a car key, lighter and easier to carry. Easy to carry, its size can be easily put into a pocket wallet, saving you more space.
