BIA Technology: Understanding the Science Behind Metrolex Scales

A Brief History

BIA technology emerged in the 1960s when researchers discovered that the body's electrical conductivity could be used to estimate body composition. Long reserved for medical and sports settings, it was expensive and required a specialized operator.

It wasn’t until the early 1990s that the first home scales appeared on the market. Since then, technological advances and improved algorithms have made these devices more accurate, faster, and accessible to the general public — like the Metrolex scales many Canadians use today.

How Does BIA Technology Work?

BIA measures the body's resistance to a very low electrical current (harmless and imperceptible). Each tissue conducts differently:

• Muscles, rich in water, allow current to pass easily.
• Fat and bones offer more resistance.

Based on these data, Metrolex scales calculate several essential indicators, including:

• Body fat
• Muscle mass
• Body water percentage
• Basal metabolism
• Visceral fat

CF-577: Dual-Frequency Precision

The Metrolex CF-577 uses two frequencies (5 kHz and 250 kHz), providing more reliable readings of superficial and deep body layers.

This technology approaches a margin of error of ±3% compared to DEXA, the medical reference for body imaging.

MX-F500: Professional Four-Frequency Analysis

The Metrolex MX-F500 goes further with DSM-BIA technology using four frequencies: 5 kHz, 50 kHz, 250 kHz, and 500 kHz.

Why Four Frequencies Matter:

• Ultra-detailed multi-layer analysis: better distinction between deep tissues, visceral fat, and muscle mass.
• Advanced segmental measurement: arms, legs, and torso analyzed separately for a complete clinical profile.
• More reliable results despite hydration, temperature, or posture variations.
• Automated professional reports: PDF sent by email or direct printing, ideal for clinics and sports centers.

Scientific Reliability

Multi-frequency BIA technology is validated by rigorous clinical studies. Metrolex devices show over 97% correlation with DEXA systems.

For optimal results:

• Weigh yourself in the morning on an empty stomach.
• Avoid exercise before measurement.
• Be barefoot and remain still.

An Essential Tool for Health and Performance

Multi-frequency BIA has become indispensable for:

• nutritional tracking,
• sports evaluation,
• detecting water imbalances,
• monitoring muscle mass or visceral fat.

Metrolex models combine accuracy, connectivity (Wi-Fi/Bluetooth), and an intuitive interface, making data easy to analyze even for beginners.

The Future of BIA Technology

The next generations of Metrolex scales will integrate more artificial intelligence and cloud analytics. They will enable:

• Highly personalized health reports;
• Early detection of metabolic risks;
• Recommendations tailored to each body profile.

Conclusion

Multi-frequency BIA technology today represents the best in non-invasive body analysis. Whether:

• CF-577 for personal or fitness tracking;
• MX-F500 for professional clinical analysis;

Metrolex provides reliable, validated tools designed to reveal what is invisible to the naked eye: your internal health.
