How Does the Sejoy Thermometer DET-306 Work?

Measuring temperature using this thermometer is very simple, even with all its options and features. Point the probe directly at the target which is either a forehead, or another body part, or the object whose temperature has to be measured. Keep the probe 2-3cm away and press and hold the Start button. The SEJOY Infrared Digital Thermometer DET-306 responds quickly, so you only need to hold the start button for 3 seconds until you hear a beep sound. Release after the beep sound and you will see the digital reading of the temperature on the Jumbo LCD screen.
