Why do you need to do a cleaning job after each
measurement?
Because infrared temperature adopts highly sensitive
technique to detect the temperature of the target object,
not only will any earwax and dust paste affect the
measurement accuracy, more likely to cause bacteria
infection. So we suggest that you should do cleaning
job well as the picture shows after you use every time.

Frequently Asked Questions and Solutions
1. (When the measurement probe is
not properly placed in the ear canal
or if the measurement distance is
too far during the measurement

2. When measurement probe is
dirty, the measurement value may
be low; we should use a cotton
swab to dip alcohol to wash the
