Odm Advanced Body Composition Analyzer

ODM Advanced Body Composition Analyzer

This instrument measures body composition by sending low‑amplitude alternating currents through the torso and limbs and analyzing the resulting impedance spectra. Multi‑frequency operation (typically 5 kHz, 50 kHz, 250 kHz) enables separate estimation of extracellular water, intracellular water, and total body water, from which fat‑free mass and fat mass are derived.

Measurement Principle and Technical Specifications

The device uses eight‑point tactile electrodes (hand‑to‑hand and foot‑to‑foot) to ensure current paths traverse both upper and lower body segments. Excitation currents are kept below 0.8 mA rms to satisfy IEC 60601‑2‑26 safety limits. Voltage sensing is performed with a 24‑bit delta‑sigma ADC, providing a resolution of 0.01 Ω.

Impedance is measured at five frequencies: 5 kHz, 50 kHz, 100 kHz, 200 kHz, 500 kHz. The raw data are processed with a Cole‑Cole model to extract intracellular and extracellular resistance values. Typical repeatability (coefficient of variation) for total body water is ≤1.5 % under standardized fasting conditions.

Measurement time	< 10 s	Stable reading after electrode contact

Applications in Industrial and Commercial Settings

Beyond consumer fitness devices, the analyzer is integrated into corporate wellness programs where longitudinal tracking of employee hydration and lean mass supports occupational health interventions. In clinical rehabilitation centers, segmental impedance data help clinicians monitor muscle atrophy or edema progression in patients undergoing physiotherapy.

Research laboratories use the multi‑frequency output to investigate fluid shifts during dialysis or to validate novel hydration biomarkers. The ODM form factor allows integration into mobile health kiosks, where the device can be housed in a rugged enclosure with optional battery operation for field studies.

Customization Options (ODM)

Enclosure material: ABS polymer, powder‑coated aluminum, or medical‑grade stainless steel.
Electrode type: disposable snap‑on, reusable stainless steel, or textile‑integrated dry electrodes.
Communication interfaces: USB‑C, Bluetooth 5.0, Wi‑Fi, or RS‑485 for PLC integration.
Software: configurable data export (CSV, HL7), multi‑language UI, optional cloud‑API for remote monitoring.
Calibration: factory‑set with traceable saline standards; user‑adjustable gain available via service menu.

Quality Control Philosophy

Each unit undergoes a three‑stage test: (1) electrical safety verification according to IEC 60601‑1, (2) impedance linearity check using precision resistor networks across the full frequency sweep, and (3) biological validation with a panel of volunteers whose composition is measured by dual‑energy X‑ray absorptiometry. Only devices meeting ≤2 % error on fat‑mass versus DXA proceed to final packaging.
