1. Summary of infrared
Thank you for choosing our Infrared
Thermometer. The MDI231 Infrared
Thermometer is used to measure an
objects temperature based on the re-
lationship between temperature and
measurable infrared radiation. Sim-
ply aim the unit's probe toward the
surface to be measured to obtain a
quick and accurate temperature. To
ensure proper use, please be sure
to read this user manual carefully,
paying close attention to the safety
precautions.
• In order to use this product correct-
ly, please read the user manual be-
fore use.
• In order to properly use this pro-
duct, please carefully read the full
text of this manual before using, in
particular the "safety precautions"
section.
• Please keep the instructions on the
side for easy checking.
Basic principles:
All objects above absolute zero tem-
perature emit certain percentage of
infrared radiation energy based on
its temperature. The amount of the
radiation energy and the distribution
of the wavelength have very close
relationship. When human body tem-
perature in 36-37°C, it emits wave-
length 9-13um of infrared radiation.
Based on this principle, according
