Transtek Body Fat Analyzer GBF-1251-B1 applies BIA (Bio-impedance Analysis)
technology. A small amount of weak current flows through the human body so as to detect
the bio-impedance and estimate BMI, body fat, body water, muscle mass and bone mass.
The electrical current is small and may not be felt.

This BIA technology is cheap, safe, non-invasive, toxic-free and harmless. It also
possesses the characteristics of simple operation and abundant information.

The current mentioned above is less than 0.5mA. However, please be aware that
anyone with an wearable or implantable medical electronic instrument, such as a
pacemaker, must avoid using this device.

The intended use of this device is for healthy children 10-17 years old and healthy adults.
