Important: Read this First!
This thermometer reads
skin surface
temperature
and
extrapolates
body temperature from that
reading. It does
not
read body temperature
directly
.
All
non-contact infrared thermometers that measure
body temperature work this way.
To get an accurate reading, point the thermometer
at the side of the forehead or behind the ear where
the skin temperature tends to be constant.
That skin temperature will always be at least several
degrees lower than core body temperature, for
example 92°F/33.3°C. A “body” or “forehead”
infrared thermometer estimates core body
temperature from the skin surface temperature
reading.
So instead of displaying, for example “92°F/33.3°C”,
the actual surface temperature of the forehead, it
applies a formula to this reading to calculate body
temperature, and displays for example
“98.3°F/36.8°C”. This is an
estimate
of core body
temperature based on the
typical average
relationship between forehead surface temperature
and core body temperature.
