Feature: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.Specification:Item Type: ThermometerMaterial: ABSGross Weight: Approx. 42g / 1.5ozColour: BlackPower Supply: 2 x 1.5V 3A Batteries (Not Included)Infrared SensorDisplay Mode: LED Digital DisplayMeasuring Distance: 3~5cmHuman Body Measurement Range: 32℃ ~ 42.9℃ (89.6℉ ~ 109.4℉)Object Measuring Range: 0℃ ~ 80℃ (32℉ ~ 176℉)Celsius Accuracy: ±0.2°C: 35°C ~ 42°C / ±0.3°C: 32°C ~ 34.9°C; 42.1°C ~42.9°CFahrenheit Accuracy: ±0.4℉: 95℉ ~ 107.6℉ / ±0.5℉: 89.6℉ ~ 94.8℉; 107.8℉ ~ 109.4℉Measuring Time: 1 SecondAutomatic Screen Off Function for 8 Seconds (When not in use, enter automatic shutdown).Package List:1 x Thermometer
