5 BODY TEMPERATURE BASICS
G
enerally, you can take a body temperature on the
forehead, in the ear canal, under the armpit, in the
mouth, or in the anus. The temperature measured
at different parts of the body may differ slightly.

Variation in body temperature
N
ormal body temperature varies by the time of
day and is also affected by external factors. The
body temperature of an individual is the lowest
between 2:00 a.m. and 4:00 a.m. and the highest
between 14:00 p.m. and 20:00 p.m. An individual’s
body temperature typically changes by less than
1°C each day.
6 PRODUCT DESCRIPTION
O
verview: The IRT-200 Forehead & Ear Thermometer
measures the body temperature based on the
infrared energy emitted from the eardrum or the
forehead. Users can quickly get measurement results
after positioning properly the temperature probe
in the ear canal or forehead. It can also be used to
measure the surface temperature of object (such
as milk and water).
S
tructure: The thermometer consists of a shell,
an LCD, a measure button, a beeper, an infrared
temperature sensor, and a Microprocessor.
O
perating principle: The infrared temperature sensor
collects infrared energy emitted by the eardrum or
the skin surface. After being focused by a lens, the
energy is converted into a temperature reading by
the thermopiles and measurement circuits.

ntended use: The IRT-200 Forehead & Ear Thermom-
eter is intended for the measurement of human body
temperatures. The forehead mode is indicated for
use by people of all ages and the eardrum mode is
indicated for use by people above three months old.
C
ontraindications: Do not use the thermometer
if the ear is infected with otitis or suppuration.
