The human body is a dynamic system, the body continuously produces heat, surface also constantly much heat, so the body's temperature is not perfectly still remains the same. At the same time, with mercury thermometer to measure the same person, axillary and mouth temperature difference can reach more than 0.8 degrees. The forehead thermometer is designed according to the circumstance of human fro...

From different parts of the human body is a dynamic system, the temperature is different, and each individual differences between, there is no fixed relationship with temperature.Customers according to their different situations, the use of our function key measurements of fine-tuning.

The same part for measuring time, every time, the distance and Angle of the probe is slightly different, the forehead thermometer probe detected temperature is slightly different, so if every measurement of slightly different numerical is reasonable. This situation is suggested that a site measurement about 3 times, peak.
