Infrared thermometers usually use a lens to focus infrared light from one object onto a detector called a thermopile. The thermopile absorbs the infrared radiation and turns it into heat. ... The electricity is sent to a detector, which uses it to determine the temperature of body without any physical contact.ACCURACY MEASUREMENT - The large screen reading, 0.5 second rapid measurement temperature, can measure the human body ,object ,indoor temperature.NON-CONTACT DESIGN: Non-contact design will be more sanitary, potentially decreasing the spread of bacteria/infection. Keep the sensor less than 2 inch (5cm) from the skin and you will get a good reading.Three color backlight to remind the different temperaturte range.Temperature Measuring Range:89.6 F~109.22 F.MULTI-FUNCTIONAL:Measures not only the temperature of human body(forehead) but also the surface of object, such as, milk, food, refrigerator or anything else in your house.It is necessary for you to get the help from this temperature gun. Maybe your old parents need to be taken care of too. This thermometer can let you know if your family are having fever. It is useful and universal, can measure the temperature of water, milk, room and many other things.Measuring Range:89.6℉~109.22℉ , Measure time:0.5 s , Menory Data:32 groups(recycled) , Storage temperature:25 ℃~+55℃ , Humidity:≤90 % , Accuracy:+/-0.2℃/+/-0.4℉ , Working Temperature:16℃~35℃;
