RJL Company History

Our founder Rudolph J. Liedtke pioneered Bioelectric Impedance Analysis (BIA) technology and founded RJL Systems in 1979. Now, more than 30 years later, RJL Systems remains at the forefront of BIA development, engineering and applications. The engineering team at RJL continues to set the standards for the reliability and use of whole body measurements to assess body water and body composition. Our team is onstantly conducting research, holding trials and performing engineering updates for our BIA instruments and software to ensure that our products are the most advanced, reliable and accurate available. This vigilant adherence to scientific and ethical standards has paid off: RJL’s FDA-approved BIA instruments are recognized as the global standard, with more than 15,000 having been sold to health and medical professionals, hospitals and universities worldwide. RJL has sold BIA instruments to 31 of the US’s top 50 colleges to use for instruction. Mr. Liedtke is widely regarded as the foremost expert in BIA systems development and application.

RJL’s Quantum technology for body composition assessment is approved by the FDA as a Class 2 Medical Device, and is cited in thousands of international research studies, abstracts and peer reviewed articles. Publications featuring studies using RJL technologies include The American Academy of Nurse Practitioners, Journal of Applied Physiology, American Journal of Clinical Nutrition, Journal of Health Promotion, Journal of Parenteral and Enteral Nutrition, Journal of Exercise Physiology, and the Journal of Renal Nutrition.

While other companies strive to provide bioelectrical impedance assessment, RJL Systems continues to be the bioelectrical impedance assessment technology innovator. The RJL Systems engineering team – still led by Liedtke – continues to explore exciting new medical application and research frontiers.
