Underwater Weighing is known as the “Gold Standard” of body fat measurement. Many people refer to it as the “dunk test.” All other methods, including our Futrex ® 6100XL Body Composition Analysis System, are calibrated to to this “reference laboratory. Underwater Weighing has a margin of error of plus / minus 3%. The Futrex ® System has the same margin of error precision as underwater weighing.

Futrex ® is the only
gold standard method of measuring body fat that uses completely
safe, near-Infrared light to directly measure percent body fat.
Extensive U.S.
Government research determined that the midpoint of the biceps has a
direct correlation with the body’s overall fat level.

During measurement, the Futrex ® 6100XL Body Composition Analysis System sends a safe, near-Infrared light beam into the triceps at specific wavelengths that fat will absorb and lean mass will reflect. The light absorption is measured to determine body fat -- it’s that simple!
Body fat test results which are equivalent to underwater weighing are instantly displayed for you.
