Underwater weighing, known as "Archimedes principle",
is the most accurate method for measuring body fat. Underwater weighing measures
body density in water to determine exact body fat quantity. Usually, density
of fat is lower than density of muscle or bone groups. Therefore, a person
who has a lot of muscles is more apt to sink in water than a person who has a
lot of fat. It is desirable for an impedance measuring system to produce values
similar to underwater weighing values. However, clinical experiments are needed
to achieve this goal.
Characteristics of Health Keeper-X
Repeatability : Can exactly measure body fat regardless of sex and
age by using experimental hydrospace weight measurement data for various population
sub-groups. (Less than ±0.5% error in body fat easurement)
Accuracy of abdominal obesity measurement : All abdomen FAT amounts
and WHR(waist and hip ratio) estimated values are provided through abdominal CT
photographing research data and waist circumference measurement.
accuracy of measurement is increased : By connecting electrodes to the finger
and ankle contact area is reduced and the accuracy of results are increased.
Short measurement time : Complete measurements taken in 10 seconds
with printed results in only 1 minute.
Touch screen and voice guidance system : Easy to follow instruction
through a touch screen and voice guidance system.
No need to go barefoot : Because direct skin contact is achieved
by using the ankle electrodes.
