An infrared thermal gun is a thermometer that measures the temperature from a safe distance from the thermal radiation emitted by the object being measured in the LCD. This noncontact thermometer, or temperature gun, is certainly a more reliable device to measure the temperature of a body. It has a well-programmed sound beep system and triggers only if any human has a fever. In this system, there are two lights that illuminate green, showing the person has a normal body temperature, and another light that glows up red, indicating a fever situation. It can easily save the last twenty results of the patient in its database and can be recalled at any time for a particular patient’s analysis and medical prescription accordingly.
