1、Non Contact Measurement: The forehead temperature can be measured at a distance of 1~5cm without direct contact with human skin to prevent cross infection and make the measurement safer. 2、High Accuracy Fast Measurement: Advanced infrared detection system and high accuracy sensor ensure high accuracy (±0.2℃) and instant results (≤1s). 3、Data Storage: Forehead temperature and object temperature can be measured, and 20 sets of measurement data can be stored for analysis and reference. 4、LED Digital Display Screen: A clear 3 digit LED display, even in a dim environment, you can easily read the measurement results. If the temperature is abnormal, the alarm will issue a "didi" warning. 5、Long Lasting Power Supply: Powered by 2 1.5V 3A batteries (not included), low power consumption and long service life. Automatically shuts down when there is no operating, effectively saving power.
