Where the baby temperature gun to measure the most accurate needs to be based on the type of temperature gun to decide, if it is an ear temperature gun, measuring the ear is the most accurate; if it is a forehead temperature gun, measuring the forehead is relatively more accurate. Ear thermometer and forehead thermometer both principle and design are similar, are through the built-in infrared sensor on the body radiation of infrared energy measurement, it will be able to determine the surface temperature more accurately. The difference is that the ear thermometer due to design features, more suitable for measuring the ear canal, the temperature is also more accurate. Forehead thermometers are more accurate for forehead temperatures, but can also be used to measure surface areas such as the neck and wrists. It should be noted that since the forehead thermometer measures the temperature of the body surface, it is susceptible to the influence of the ambient temperature, resulting in a deviation in the measured temperature. If you suspect that your baby’s temperature is not normal, or if it is too high when measured with a thermometer, it is recommended that you seek medical attention.
