Fitbit Aria General Info & Specifications
Sensors
Weight and Body Fat
Four load cells measure weight. Body fat information is measured through electrical
impedance and calculated based on weight and user account data.
Body composition
The scale measures body mass using bioimpedance analysis. Indium tin oxide (ITO)
electrodes form a pattern on the top of scale and send a small, safe signal through
the body to measure impedance.
Limitations
• The Aria will accurately measure the weight of children and adults over 20 lbs.
(10 kg).
• The maximum weight limit for the Aria is 350 lbs. (159 kg).
• Body fat percentage may not be accurate for children under the age of ten.
Batteries and power
• 4 AA standard 1.5V size AA batteries included
(Operating max: 3.3V, 0.1A / 300mW)
• No power cord necessary
