Review on iHealth PT3 No-Touch Forehead Thermometer: Digital Infrared Touchless Thermometer with Ultra-Sensitive Sensors for Adults, Kids, and Babies. by Ada Dylewska ᠌

I have now been utilizing the equipment for a period of two months. I make it a habit to check the staff' temperatures first thing in the morning. If you meet all of these parameters, the gadget will show 99% accuracy; nevertheless, it will only display correctly at room temperature, which is between 19 and 22 degrees Celsius; you must also be seated away from batteries and heaters, and you must not have walked or moved around before using it. If you come from the street, or if you walked before, then the temperature on your forehead will be lower because it will have cooled down. If you just got in from the street or were walking before, you should first sit down for five minutes before measuring. Also, if you sit next to a heat source, such as a battery or a heater, your skin will heat up and show the temperature more clearly. This is because the skin is more permeable to heat. There should be no complaints about the gadget because it gives accurate results if it is used correctly and measurements are taken at the appropriate times.
