Tanita Weight, Body Fat, Body Water Scale

Tanita's body water monitor scales use Bioelectric Impedance Analysis (BIA), the same accurate technology used for body fat monitoring. BIA passes freely through the fluids contained in muscle tissue and in blood, but it encounters difficulty when passing through fat tissue, which contains little water. By using the impedance reading, gender, height, and weight, the scale can quickly and reliably calculate body fat and total body water percentages. Proper hydration is essential for life. Maintaining a healthy body water% improves all overall health and keeps you feeling energized and operating at a peak performance. As a general guideline the average TBW% ranges for a healthy adult are: Female 45 to 60% Male 50% to 65%

 Do you want to lose weight or improve your total health and fitness? Then a Tanita BF-679W Body Fat / Body Water Monitor is the right addition to your routine. A weight scale alone is not enough. This monitor calculates body fat and body water levels using bioelectric impedance analysis (BIA); sending a safe, low-level electrical signal through the body.


Using Tanita’s exclusive FDA cleared BIA technology, this scale not only measures weight and body fat, it also tells you your body water %.  BIA is quick and non-invasive, and is one of the most thorough and reliable ways to measure body composition, clinically comparable to DXA (dual-energy x-ray absorptiometry) and hydrostatic (underwater) weighing.


The BF-679W features a weight capacity of 300 pounds, it operates for greater than 2 years on four AA batteries (included).
