Simzo -- HW-F7 -- NON-CONTACT INFRARED THERMOMETER
Forehead thermometers are specifically designed to measure body temperature on a person’s forehead. They are different from what you would buy at an automotive store.
The ones at the automotive store read the temperature of an “area” an object and give you an average temperature.
Forehead thermometers are designed to read the temperature of a particular spot on the forehead and make a conversion internally and equate it an oral thermometer’s reading.
The "industrial" models you can purchase at the auto parts store will absolutely give incorrect readings if used to measure for high body temperature.
