Body fat scale is a kind of equipment for measuring body composition. Body composition refers to the content of water, muscle, fat, inorganic salts and other components in the human body and their percentage in the total mass of the human body. It can usually be divided into adipose tissue and non adipose tissue. Its mass and distribution are closely related to the health status of people at all ages. How can the body fat scale distinguish between fat and non fat tissue in the human body? In fact, it is based on a technique for measuring body composition, called bioimpedance analysis (BIA). That is, according to the different electrical impedance characteristics of human adipose tissue (FM) and non adipose tissue (FFM), with the help of the electrode placed on the human body surface, a small AC measurement current is sent to the tested human body, and the human body impedance information is extracted from the detection electrode for the determination of human fat content. Using bioelectrical impedance analysis, the body fat scale can measure and analyze the following items: Body weight, BMI, body fat rate, muscle rate, fat removal weight, subcutaneous fat rate, visceral fat area, body moisture, skeletal muscle rate, muscle mass, protein, basic metabolic capacity, body age Welland intelligent body fat scale adopts BIA measurement technology to achieve accurate body composition measurement, body data analysis, and cooperate with the exclusive app to help track the changes in body health at all times.
