Wholesale Body Composition Analyzer Scale

Body composition analyzers use bioelectrical impedance analysis (BIA) to estimate tissue composition by measuring the opposition of bodily fluids to a low‑level alternating current. The device sends a safe, multi‑frequency signal through hand‑to‑foot or foot‑to‑foot electrodes and calculates resistance and reactance values. From these values, algorithms derive fat mass, lean mass, total body water, and segmental distribution.

Operating Principle

The scale incorporates eight tactile electrodes—four on the platform for foot contact and four on handheld grips for hand contact—to enable segmental BIA. Alternating currents at 5 kHz, 50 kHz, and 250 kHz are applied sequentially, allowing the instrument to differentiate intracellular and extracellular water.

Voltage drop across each electrode pair is measured with a precision of 0.1 Ω, and the resulting impedance vectors are processed by a proprietary algorithm validated against dual‑energy X‑ray absorptiometry (DXA) reference data.

Technical Specifications

Typical Applications

In fitness facilities, the analyzer provides trainers with quantitative baselines for muscle‑fat ratios, enabling personalized program design and progress tracking. Clinical settings utilize the segmental output to assess fluid shifts in patients undergoing dialysis or edema management. Research laboratories rely on the multi‑frequency impedance data to correlate body composition metrics with metabolic studies.

Construction and Materials

The weighing platform is formed from 6 mm tempered glass with a ceramic‑coated surface that resists staining and facilitates easy cleaning. Load cells are foil‑type strain gauges rated for 0.02 % nonlinearity, providing repeatability within ±0.1 % of full scale. Electrodes are stainless‑steel pads coated with a conductive hydrogel layer to ensure consistent skin contact.

Internal circuitry is mounted on a double‑sided FR‑4 PCB with conformal coating to protect against humidity. The enclosure is ABS‑plastic with a UL‑94 V‑0 flame rating, providing mechanical rigidity while keeping the overall mass under 12 kg.

Quality Assurance and Testing

Each unit undergoes a three‑point calibration using certified traceable weights (5 kg, 50 kg, 150 kg) before shipment. Impedance accuracy is verified against a precision LCR meter with a tolerance of ±0.5 % across the operational frequency range. Ingress protection is confirmed by spray testing per IEC 60529.

Functional testing includes a 100‑cycle load‑unload sequence to assess creep and recovery of the load cells, followed by a 48‑hour burn‑in of the electronics at 40 °C to stabilize component values. All test results are recorded in a traceable batch record.

Customization Options

• Electrode configuration: 4‑foot only, 8‑foot/hand, or handheld‑only variants
• Platform dimensions: standard 350 mm × 350 mm or enlarged 400 mm × 400 mm for bariatric use
• Interface upgrades: addition of Wi‑Fi module or Ethernet port for network integration

• Software: optional SDK for third‑party app development or cloud‑based data storage

Ordering Information

Minimum order quantity for wholesale is ten units, with volume discounts available at fifty units and above. Production lead time is typically four weeks after receipt of purchase order, subject to material availability. Sample units can be arranged upon request, with shipping costs borne by the requester.

Frequently Asked Questions

Can the electrode layout be modified for specific populations?

Yes, the electrode count and spacing can be adjusted to accommodate pediatric, geriatric, or amputee users; such changes require a new tooling quote and validation against reference methods.

What information is needed to obtain a quotation?

Please provide the desired quantity, any customization requests (platform size, electrode type, interface), preferred delivery destination, and required documentation (e.g., calibration certificate, CE declaration).

How is quality inspected before shipment?

Each finished device passes a visual inspection, functional test suite, and a final impedance verification; a batch test report is included with the shipment.
