Improve Patient Assessment
Easy-to-operate. Non-invasive and safe.
The MA801 features an intuitive touchscreen interface and voice guidance throughout the measurement process, requiring minimal training to operate safely and properly. Completing an advanced scan in less than a minute, the MA801 uses segmental multi-frequency measurement technology to provide clinically validated results you can trust.
Key Health Indicators

Body Fat Analysis
Compare subject’s body fat with their respective gender, age, and ethnic group. Evaluate visceral and subcutaneous fat area in the abdominal area, as well as segmental fat calculations.
Comparison of Cellular Status
BIA results have traditionally been less accurate for subjects with illnesses affecting body water. Bioelectrical Impedance Vector
Analysis allows practitioners to monitor fluid and cellular status even for patients with “abnormal” hydration, increasing BIA reliability in clinical use.
Cellular Health Indicators
Phase Angle is a critical screening tool for assessing cellular health, offering an important indicator for identifying subjects that may be outwardly healthy with potential health complications.
Muscle Analysis
Through measurement of cellular quality, the MA801 can provide estimates of potential handgrip strength, used as a clinical marker for poor mobility, and a better predictor of sarcopenia than muscle mass. By comparing grip strength with comparable group percentiles, muscle strength level can be placed in context.
Hydration Status
Abnormal body water is an important early warning sign for a variety of health complications. Precise tracking and management of extracellular and intracellular fluid is of utmost importance in a wide variety of diseases, including but not limited to cardiac and renal deficiency. Compare Extracellular and Intracellular water proportion to evaluate imbalance, and track body water changes as frequently as needed.

Designed for patients with abnormal hydration
Bioelectrical Impedance Vector Analysis (BIVA)
The BIVA module uses direct measurements of reactance and resistance to evaluate a subject’s hydration and cellular status. Why is this so important? Abnormal body water can cause measurement error in traditional predictive equations, a crucial flaw in traditional BIA devices. Because BIVA doesn’t rely on regression equations, health professionals can use the easily interpreted chart to reliably conduct critical preliminary screening, even for individuals with abnormal hydration, by comparing their results with the general population.

How healthy are the cells in your body?
Phase Angle
Quantity doesn’t tell the whole story. Because two people with identical muscle and fat percentages or mass aren’t necessarily equally healthy, health professionals can utilize phase angle, which decreases with illness
and aging - as a way to measure cellular quality. Compare the subject’s phase angle with normal range for their age and gender group using the MA801’s percentile chart.
Clinically validated results
High Correlation with DXA
Charder’s years of research in the field of Bioelectrical Impedance Analysis include utilization of Artificial Neural Networks, with algorithms formulated and validated using “gold standards” such as CT and DXA for results you can trust.

Intuitive and user-friendly voice-guided interface
Voice-guided measurement procedure
10.1-inch color touchscreen combined with voice guidance throughout measurement procedure makes the MA801 easy-to-operate, improving reliability and reproducibility of results. Measurement results are organized clearly on a professional result sheet, and can be transferred to a PC for advanced analysis and data management.

Body Fat Analysis
Utilize Body Fat Percentiles to place results in context
“Normal range” for body fat is affected by age, gender, and ethnicity. The MA801 makes it easy for health professionals to compare a subject’s body fat percentage with their population group, for a more effective evaluation of obesity risk. 
Evaluate body fat by location
Abdominal visceral and subcutaneous fat
It isn’t just about the amount of fat, but where it’s located. In addition to fat mass in different body segments, the MA801 provides visceral fat area, which has a higher correlation with obesity-related diseases than whole-body fat percentage.



Muscle Analysis
Identify patients at higher risk for falls
Muscular strength is affected by both mass and quality. Because muscle quality can deteriorate more rapidly than mass with age, evaluation of muscular strength in addition to mass is particularly crucial in senior
populations, to screen for fall risk. If subject’s actual grip strength is lower than predicted through cellular analysis, we recommend a more detailed health check.


Hydration Status
Evaluate Body Water Balance with Edema Index
Extracellular Water Proportion is a major risk indicator for all-cause mortality, kidney deficiency, and cardiovascular disease, providing potential early warning for health complications requiring preventative action.
