seca mBCA 555

The new generation of body composition analysis

Medically validated and adjustable to fit your needs

The new seca mBCA 555 is the result of our long-term cooperation with medical experts and research in the field of body composition. In addition to outstanding precision and accuracy, you receive an completely user-friendly and practical BIA solution with an optional ultrasound length measurement and brilliant cloud-based software with the seca mBCA 555.

Make body composition visible and easy to understand

The graphic presentation of measurement results established in cooperation with medical professionals gives you valuable support for diagnosis and therapy. Within seconds, you’ll receive a complete body composition image plus the option of having specific questions answered thanks to a detailed analysis.

More freedom with cloud-based software

Thanks to the new cloud-based software delivery, all administrative IT issues are taken care of for you. It ensures you can concentrate fully on your medical work.

  • Quick and clear graphics with normal ranges
  • Normal ranges can be defined individually as needed
  • Professionally prepared templates for the most important fields of application
  • Customizable printout including notes and explanations for patients
  • Trend analysis allows progress to be tracked in support of patient motivation and engagement
  • Software suitable for all common devices (whether tablet or laptop)

Sensitive patient data is saved in an encrypted form and protected from third-party access

seca myAnalytics:

Direct access for patients

This cloud-based software ensures that you can provide measurement results to your patients at any time. You assign them a personal login that your patients can use to access their information. This allows them, regardless of the device used, to track changes in their body composition.

Bioimpedance analysis trusted by the medical profession

  • Unique accuracy by validation from whole-body MRI (skeletal muscle mass) and 4C model (fat mass)
  • Validation studies are completely and transparently published in the European Journal of Clinical Nutrition, among others (1,2)
  • Validated for individuals affected by obesity (starting at a BMI of 30 kg/m²) (3)
  • Comprehensive, personalized normal ranges based on over 3,000 multiethnic subjects (4)
