How Does TANITA BIA Technology Work?
High-level accuracy, available in the home
TANITA is the founder of Bioelectrical Impedance Analysis (BIA) and the first to bring a so-called body fat analyser to the market. By continuing to innovate and develop, we have become the world leader in health monitoring and the only manufacturer making it available to both professionals and home users.
Body Composition Scales
Using TANITA Bioelectrical Impedance Analysis Technology
Biometric Impedance Analysis
When a customer stands on a TANITA scale, a very low, safe electrical signal is sent from four metal electrodes through their feet to their legs and abdomen. The electrical signal passes quickly through water that is present in hydrated muscle tissue but meets resistance when it hits fat. This resistance, known as impedance, is measured and input into scientifically validated TANITA equations, to calculate body composition measurements.
Dual and Multi-Frequencies
Additional frequencies provide an exceptional level of accuracy compared to single frequency monitors. This information is essential for providing the health status of a person and indicating health risks such as severe dehydration or edema.
Multi-Frequency BIA Technology
TANITA Multi-Frequency Monitors are able to measure bioelectrical impedance analysis at three or six different frequencies. The lower frequencies measure the impedance external to the cell membrane. The higher frequencies are able to penetrate the cell membrane. By measuring impedance at both the lower and higher frequencies it is possible to estimate extracellular water (ECW), intracellular water (ICW) and Total Body Water.
Dual frequency BIA technology
TANITA body composition monitors with Advanced Dual Bioelectrical Impedance Analysis Technology use two different frequencies to capture your body composition data. By using different frequencies, a higher accuracy of measurements can be achieved.
Why is TANITA BIA technology the most accurate?
The original prediction equations used in TANITA software were devised by world-renowned body composition expert Professor Steven Heymsfield and his research team at St Luke’s Roosevelt Hospital, Columbia University, New York. Extensive independent research has proven that the accurate prediction of an individual’s body composition can only be determined if a range of parameters are included in an algorithm, such as gender, age and height and weight.
TANITA BIA technology has been more extensively validated against alternative body composition techniques than any other company and the findings have been published in international medical journals. In addition, TANITA monitors have been used in hundreds of independent research studies worldwide. TANITA is regarded by the scientific community as the gold standard in BIA technology and the TANITA Medical Advisory Board ensures TANITA remains at the forefront of scientific advances.
TANITA continually invests in numerous research projects that focus on enhancing understanding of key health and fitness issues, including areas such as childhood obesity, optimising physical performance and sarcopenia in the elderly. Our aim is to work with experts to develop tools and technologies to assist all healthcare and sports professionals in providing the best possible services and to help people enjoy healthier lives.
Precise weight measurements are essential for calculating accurate body composition measurements. TANITA prides itself on manufacturing highly accurate weighing mechanisms in both its home use and professional models. All TANITA medically approved professional monitors have been awarded NAWI Certification as well MDD Class IIa, FDA and CE Approval ensuring the highest standards are met.
TANITA has grown through continuous product innovation and a commitment to maintaining the highest manufacturing quality standards. The company operates award-winning manufacturing facilities in Japan and China and all TANITA medical products meet strict international quality standards and are independently quality-controlled.
