Using cable-based, wrist-to-ankle electrode systems, RJL eliminates inconsistencies caused by posture, hydration, or surface contact. Its compact, lightweight analyzers are highly portable and field-tested—ideal for clinical, mobile, or global health applications where accuracy and portability must go hand-in-hand.

RJL’s systems provide precise, repeatable measurements that make them ideal for monitoring body composition trends over time. Unlike many consumer-grade or proprietary BIA devices, RJL’s raw data outputs—resistance, reactance, and phase angle—allow for consistent longitudinal analysis. This makes it an invaluable tool for clinicians, researchers, and health professionals seeking to track patient progress, evaluate interventions, or support long-term health goals.

RJL Systems BIA instruments are affordable and require minimal maintenance. They are ideal for both small practices and large institutions that require accuracy and repeatability in body composition analysis. Its affordability and performance make it one of the most sustainable investments in the BIA market.

All RJL instruments directly measure the vectors of impedance known as resistance and reactance and are displayed on the instrument and illustrated on all software.  This is essential for scientific calculations and research that can be shared. Researchers and clinicians can use these accurate values for clinical, athletic, military and epidemiological cases across all populations – from pediatrics to geriatrics.
