Frequently Asked Questions
What body composition metrics can be measured?
Our solution supports comprehensive metrics including body fat %, muscle mass, bone mass, body water %, BMI, BMR, visceral fat level, and protein percentage.
What is the difference between single-frequency and multi-frequency BIA?
Single-frequency (50kHz) BIA is suitable for basic body composition analysis. Multi-frequency (5kHz~100kHz) BIA provides more accurate segmental analysis and can differentiate intracellular/extracellular water.
How many user profiles can be stored?
Our high-end MCU (BH67F2493) supports 8+ user profiles with automatic user recognition. The mid-range MCU (BH67F2476) supports 4 user profiles.
What is the typical measurement accuracy?
Impedance measurement accuracy is ±1% across 50Ω~1.5KΩ range. Body composition metrics accuracy depends on algorithm calibration, typically ±3-5% for body fat percentage.
Is smartphone connectivity supported?
Yes, our high-end MCU supports BLE/Wi-Fi connectivity for smartphone app integration, enabling trend tracking, goal setting, and cloud synchronization.
Can the solution support segmental BIA analysis?
Yes, our high-end MCU (BH67F2493) supports 8-electrode segmental BIA for separate analysis of arms, legs, and trunk.
