The Cortex MetaLyzer 3B – R3

Portable Breath-by-Breath system

The Cortex MetaLyzer 3B-R3 is a portable high resolution Metabolic analyser with Breath-by-Breath technology. The system allows a complete medical analysis of the functionality of a person’s lung, heart and metabolism at rest and under stress.

Measure what matters to you

Whether in the fitness club or the doctor’s office, whether in the hospital or the Olympic test center, use the METALYZER 3B together with the powerful application software MetaSoft Studio to exploit the full potential of a Metabolic analyser.

Take it with you

Due to its low weight and compact dimensions, the Cortex MetaLyzer 3B can be easily transported from one measuring station to the next. The device comes supplied with the Aluminium carry case as pictured, giving you one place to keep everything and easily transport from location to location.  Perhaps you have labs running in different buildings, or need to travel from place to place to meet a client – the Cortex MetaLyzer is able to quickly break down and pack up.

Remarkably low maintenance

The Cortex MetaLyzer has been designed in such a way that helps minimise calibration and maintenance. A 2-part Gas sensor calibration is only required once every 28 days and the volume sensor comes pre-calibrated*. The only other thing you need to do is clean and sterilise between tests.


*Cortex Disposable Turbines are single use, pre-calibrated. Also available is a Re-useable turbine, requiring calibration with a 3L Syringe each test.
