Measurement principle Forehead temperature: Any object emits infrared rays when it is above absolute zero (-273 ° C). This product receives infrared rays from the forehead of the human body through an infrared sensor and obtains the temperature data to obtain the body temperature. Scope of application The body temperature of the subject is displayed by measuring the heat radiation from the forehead of the human body. Technical Parameters Power supply voltage: DC3V (2 AA alkaline batteries) Measurement range: Forehead temperature mode 32.0 ° C ~ 42.9 ° C; Calibration mode 0 ° C-99.9 ° C Maximum allowable error: within the display range of 35.0 ° C ~ 42.0 ° C is ± 0.2 ° C; other ranges are ± 0.3 ° C. Memory storage: 32 sets of latest measurement data can be stored Automatic shutdown: within 60 seconds Host size: 105x48x150mm Caution 1. The distance between the forehead and the thermometer must be 1 ~ 5CM to avoid affecting the accuracy of the measurement. 2. Do not dispose of the battery in a hazardous area, which will cause environmental pollution. 3. The product is not waterproof. Please be careful not to let liquid enter the product.
