Why must a probe cover be used with the Microlife ear thermometer?
The Microlife ear thermometer?s calibration is set with a probe cover. So, measurements without a probe cover result in poor measurement accuracy. In addition, use of the thermometer without a cover can result in transmission of germs. (unacceptable hygiene) Even a small amount of earwax on the probe tip allows bacteria and fungus to grow outside the ear! Please use a new cover for each measurement. The probe cover also protects the infrared sensor from earwax, which can destroy the sensor.
