Introducing TANITA's BF-680W Body Monitor Scale, powered by Bioelectric Impedance Analysis (BIA) technology for precise body fat monitoring. BIA effortlessly navigates through muscle tissue and blood fluids but faces resistance in fat tissue due to its low water content. Leveraging impedance readings, gender, height, and weight, this scale accurately calculates body fat and total body water percentages. Optimal hydration is vital for vitality. Enhance overall health by maintaining a healthy body water percentage, staying energized, and performing at your peak.
