For most of the last 25 years RJL Systems has provided the Online Interactive BIA service, which allowed anyone with an internet connection to generate a one-page body composition report, regardless of whether they have our body composition software installed.

The equations in this application used RJL Systems BIA products and BIA electrodes to create the body composition formulas.

A more visual version of this application is at Visual Body Composition 3.0 that uses Google charts and graphs with an interactive weight manager.

Extended warranties and product upgrades with 3 year warranty are available by calling
