Inquire NowSegmental Body Composition Analyzer
A segmental body composition analyzer measures fat, muscle, and water distribution across specific body regions using multi‑frequency bioelectrical impedance. The device applies alternating currents at several frequencies to differentiate intracellular and extracellular water, enabling regional assessment of lean mass and adipose tissue. This capability supports industrial health monitoring, ergonomic research, and workforce wellness programs where localized composition data informs interventions.
Working Principle
The analyzer sends low‑amplitude electrical currents through electrodes placed on the hands and feet. Impedance is measured at frequencies ranging from 5 kHz to 500 kHz, allowing the system to solve the Cole‑Cole model for each segment. By calculating resistance and reactance values, the device derives extracellular water, intracellular water, and subsequently estimates fat‑free mass and fat mass for the trunk, arms, and legs.

Design and Construction
The enclosure is fabricated from ABS‑PC blend with a surface resistivity below 10⁹ Ω/sq to prevent static buildup during electrode contact. Electrodes are stainless‑steel snap‑type contacts rated for >10 000 mating cycles, ensuring consistent impedance measurement over the device lifespan. Internal circuitry employs a 24‑bit ADC with programmable gain amplifier to resolve impedance changes as small as 0.01 Ω.
Measurement Capabilities
- Segmental fat mass (kg and %)
- Segmental fat‑free mass (kg)
- Total body water, intracellular water, extracellular water
- Basal metabolic rate estimated via validated equations
- Phase angle at 50 kHz for each segment (indicator of cellular health)
Industrial Applications
In manufacturing environments, segmental analysis helps identify musculoskeletal imbalances that may predispose workers to repetitive‑strain injuries, allowing targeted ergonomic adjustments. In research facilities studying occupational health, the device provides longitudinal data on how shift work or exposure to specific agents alters regional fluid balance. For corporate wellness programs, the ability to track changes in trunk fat versus limb muscle supports personalized intervention planning and ROI evaluation.
Quality Assurance
Each unit undergoes a four‑point impedance verification using precision resistors traceable to national standards before shipment. Firmware includes a self‑diagnostic routine that checks electrode contact quality, signal-to-noise ratio, and temperature compensation on every startup. Production follows ISO 9001‑based process controls, with statistical process control charts monitoring critical parameters such as gain stability and baseline offset.
Customization Options
Electrode cable length can be adjusted from 0.5 m to 2.0 m to accommodate different mounting configurations. The analyzer can be ordered with a wall‑mount bracket, a portable carrying case, or an integrated touchscreen interface. Software packages are available for data export in CSV, HL7, or custom API formats, and can include license‑based access to cloud‑based analytics dashboards.
Frequently Asked Questions
Can the measurement sites be reconfigured?
The standard configuration measures five segments; additional electrodes for neck or hip assessment are available as optional accessories and require a firmware update.
What information is needed for a quotation?
Please provide the desired electrode length, any required accessories (case, bracket, wireless module), and the preferred data‑output interface so we can tailor the bill of materials.
How is the device calibrated in the field?
Field verification uses a supplied precision impedance checker; the procedure takes under five minutes and adjusts gain factors via the built‑in calibration menu.
