A body composition analyzer is a device that assesses your BMI, muscle mass, and body fat. ... was first developed in South Korea in the late '90s as an alternative to traditional scales. By the ...
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).

Hydrostatic weighing, also referred to as underwater weighing, hydrostatic body composition analysis and hydrodensitometry, is a technique for measuring the density of a living person's body. It is a direct application of Archimedes' principle , that an object displaces its own volume of water.
The equation (the squared value of height divided by impedance measurements of the right half of the body) showed a correlation coefficient of 0.92 with total body water. This equation, Hoffer proved, is known as the impedance index used in BIA. [16] In 1983, Nyober validated the use of whole body electrical impedance to assess body composition ...
Irrespective of the location from which they are obtained, the fat cells in humans are composed almost entirely of pure triglycerides with an average density of about 0.9 kilograms per litre. Most modern body composition laboratories today use the value of 1.1 kilograms per litre for the density of the "fat free mass". [8]
In 1912, the company name changed once again, to Toledo Scale Company. [8] Additionally, a new scale line featuring a double pendulum mechanism and a dial face was introduced and was most suited for industrial applications. [9] In 1957, Reliance Electric Co, merged with Toledo Scale Co. Reliance paid about $70 million in stock for the purchase ...
