Exergen Temporal Scanner 2000C - Manual (Page 4)

The TemporalScanner has patented software, providing arterial heat balance.
This unique process determines temperature by accurately measuring the
balance between the tissues warming from arterial blood and tissues cooling/
warming caused by heat loss/gain to the environment.
Why take temperature measurements at the skin surface
over the temporal artery?
The best place to measure temperature is the center of the heart, but this
can be done only under a doctor’s supervision. Doctors know that measure-
ment of the blood temperature in a major artery accurately reflects true
body temperature. The TemporalScanner Thermometer is designed to
measure the temperature of the skin surface over the temporal artery, a
major artery of the head.
The temporal artery is connected to the heart via the carotid artery, directly
leading from the aorta, the main trunk of the arterial system. It offers con-
stant blood flow. It is the only such artery positioned close enough to the skin
surface to provide access needed to take an accurate measurement. It is
easy to use because it is ideally located at the front portion of the forehead.
The TemporalScanner is easier and gentler to use than other types of meas-
urement devices such as oral, rectal, underarm and in-ear thermometers
because it is truly non-invasive.
How does the TemporalScanner Thermometer work?
As you gently stroke the thermometer across the forehead crossing over
the temporal artery, the sensor in its probe performs two processes:
First it scans like a video camera, capturing naturally emitted infrared heat
from the arterial blood supply at about 1000 times per second, locking in
the highest temperature it senses and;
Second, at the same time, a patented system measures the ambient tem-
perature of the area where the temperature is being taken. The patented
“arterial heat balance” (AHB) software then synthesizes the two separate
readings to accurately determine and display body temperature.
As with any thermometer, taking temperatures properly is critical to obtaining
accurate temperatures, so please read all instructions carefully and thoroughly
before using this product.
