Budget Friendly BIA Body Composition Analyzer Machine

The system employs multi‑frequency bioelectrical impedance to estimate total body water, extracellular water, intracellular water, fat‑free mass, and fat mass. Measurement currents remain below 0.5 mA, ensuring safety for repeated use.

Working principle

A low‑amplitude alternating current is injected through surface electrodes placed on the hands and feet. The resulting voltage drop yields impedance values at 5 kHz, 50 kHz, and 250 kHz frequencies.

Using Cole‑Cole modeling, the analyzer separates extracellular and intracellular resistance, allowing calculation of body water compartments. Derived metrics include fat‑free mass from hydration assumptions and fat mass by difference.

Typical applications

• Fitness centers tracking member progress over training cycles
• Wellness clinics providing baseline health assessments
• Corporate wellness programs for employee health screening
• Research studies requiring longitudinal body‑composition data
• Rehabilitation centers monitoring fluid shifts during therapy

Quality assurance and calibration

Each unit undergoes factory verification against a reference DEXA scanner using a cohort of 20 subjects with varied BMI. Repeatability is expressed as coefficient of variation <1.5 % for total body water.

Field calibration is performed with a precision resistor network simulating known impedance values; adjustment software corrects gain and offset drift.

Customization options

Electrode cables can be supplied in lengths from 0.8 m to 2.0 m to accommodate different mounting heights.

The enclosure color and branding panels are adjustable to match corporate identity.

Software interfaces support HL7 or CSV export; optional Wi‑Fi module enables wireless data transfer to hospital information systems.

Frequently asked questions

• Can the measurement frequency be changed? Yes, the firmware allows selection of any subset of the three standard frequencies or addition of custom frequencies upon request.
• What information is needed for a quotation? Required details include intended usage environment, electrode preference, desired output format, and any regulatory certifications needed for the target market.
• Is the device compliant with medical device regulations? The analyzer is designed to meet IEC 60601‑1 safety standards; final certification depends on the completed technical file and local authority review.
• How are software updates delivered? Updates are provided via USB stick or secure download link; version control logs are maintained for traceability.
