Sensors

WEIGHT AND BMI

Four load cells measure weight. BMI is calculated and displayed based on weight.

BODY COMPOSITION

The scale measures body mass using bioimpedance analysis. ITO electrodes form a pattern on the top of scale, and send a small, safe signal through the body to measure impedance.

WARNING

Do not use if you have a pacemaker or other internal medical device, or are pregnant. Not intended for use by children under 10. Always consult your physician. Slippery when wet.
