Measure your own body composition

As soon as you open the NEO Health ONYX you will notice this is more than an ordinary scale to just measure your weight. This is a whole different ball game! The ONYX is a real body composition monitor, that will measure your weight, and in addition your body fat, body water, muscle mass and bone mass.


Body Weight

Body Fat %

Bone Mass %

Seamless Bluetooth Connectivity

Bio Electric Impedance Analysis

This is all possible through electronics, the ONYX is based on BIA (Bio-electric Impedance Analysis) Technology. Through 4 small electrodes it sends small shocks that go through your body to measure every aspect. The ONYX measures through resistance and since fat is more resistance towards electricity than water and muscles it can measure all 3 of them. Also the bone mass is measured through the BIA Technology.

Muscle Mass %

Body Water %


Mobile App Platform

Easy And Efficient

Though there are more accurate methods to measure Body Fat, Body Water and Muscle Mass, little electric shocks are by far the easiest since almost no knowledge is required to make a Body Composition, while the other methods are far more complicated.
