Wholesale Smart Scale Body Composition Analyzer

Core Measurement Technologies

The device employs multi‑frequency BIA at 5 kHz, 50 kHz and 250 kHz to differentiate intracellular and extracellular water, enabling segmental analysis of arms, legs and trunk. Four stainless‑steel electrodes are positioned on the platform surface to ensure consistent contact impedance.

Measurement Parameters and Ranges

The analyzer reports the following composition values, each derived from the impedance data and validated against reference methods:

• Body fat percentage: 3 %–50 %
• Skeletal muscle mass: 15 kg–55 kg (adult range)
• Visceral fat rating: 1–30 (arbitrary units)
• Total body water: 25 L–55 L
• Bone mass: 1.5 kg–4.5 kg
• Basal metabolic rate: 800 kcal/day–2500 kcal/day

Design and Construction

The weighing surface is 6 mm tempered glass with a printed ceramic coating that resists scratches and chemical exposure. The chassis is made of impact‑modified ABS with a reinforced rib structure to withstand loads up to 200 kg. Electrodes are flush‑mounted 316L stainless steel pads, each 12 mm in diameter, spaced to provide uniform current distribution.

Data Connectivity and Power

Communication options include Bluetooth 5.0 (BLE) for real‑time sync to mobile apps and an optional Wi‑Fi module for LAN integration. Power is supplied by a rechargeable 18650 lithium‑ion cell delivering up to 180 days of operation at 15 measurements per day; charging occurs via a USB‑C port with 5 V/1 A input.

Calibration and Accuracy Specifications

Weight accuracy is ±0.5 % or ±0.2 kg, whichever is greater, verified with calibrated Class M1 weights. Body fat percentage accuracy is ±1.5 % when compared to dual‑energy X‑ray absorptiometry (DXA) on a sample of 120 adults. Impedance repeatability is better than 0.8 % CV across 10 consecutive measurements.

Industrial Applications

In corporate wellness programs the scale provides quick baseline data for employee health risk assessments, allowing interventions to be tracked quarterly. Fitness centers use the segmental output to tailor resistance training programs, detecting asymmetries between limbs. Clinical settings benefit from the non‑invasive nature for monitoring fluid status in dialysis or cardiac rehabilitation patients, where changes in extracellular water are clinically significant.

Quality Assurance and Testing

Each unit undergoes ingress protection testing to IPX4 (splash resistance) and a 1‑meter drop test onto concrete to verify mechanical robustness. Electromagnetic compatibility is assessed per IEC 60601‑1‑2 for emissions and immunity. Traceability is maintained through lot‑controlled PCB assemblies and calibrated load cells, with calibration certificates available on request.

Customization Options

OEM customers can request laser‑etched logos on the glass surface, alternative electrode layouts for specialized segmental protocols, firmware adjustments for specific data output formats (HL7, JSON), and customized packaging ranging from single‑unit cartons to palletized bulk packs with foam inserts.

Frequently Asked Questions

Can the electrode configuration be modified for segmental protocols?

Yes, the number and placement of stainless‑steel pads can be adjusted to support 8‑point or 16‑point segmental analysis, subject to tooling and validation costs.

What information is required to obtain a quotation?

Please provide annual volume, desired branding placement, any required certifications (CE, FCC, RoHS), and preferred shipping terms (FOB, CIF).

How is product quality verified before shipment?

Each batch undergoes a 100 % functional test, a visual inspection for glass defects, and a random sample is subjected to environmental stress testing (temperature cycling, humidity).
