The METALYZER 3B is a portable high resolution CPET/Spiroergometry system with Breath-by-Breath technology.

The METALYZER CPET system allows a complete analysis of the functionality of a participants’s lung, heart and metabolism at rest and under stress.


  • Ultra-lightweight, Portable Breath-by-Breath system (580g)
  • Internal battery allowing a 12-hour running time (available as an option)
  • Bluetooth LE for connection to HF, SpO2, power meters and other measuring devices
  • Interfaces to numerous types of ECGs
  • USB or Bluetooth connection to a PC
  • Front display with LED status indicators
  • Push-pull connectors protecting against reverse polarity and damages
  • Low maintenance
  • Long calibration intervals
  • O2 sensor with long lifespan

The METALYZER CPET System can be used in fitness clubs, high-performance training centers, medical facilities, research labs or teaching institutions to provide cardiopulmonary exercise testing/resting metabolic rate information. Due to its lightweight, the METALYZER can be portable from one measuring station to another. You are able to operate the system with or without an electrical supply, due to the large internal battery capacity which is optional.

MEASURING BASAL METABOLIC/RESTING METABOLIC RATE: The CORTEX CANOPY Interface (optional) for METALYZER 3B CPET System can also measure basal metabolic and resting metabolic rate without your participant feeling any discomfort from wearing the traditional mask.


  • reliable measurement

  • particularly suitable for long-duration measurements (without a mask)

  • easy to clean and disinfect

  • fully automatic control of the hood ventilation

  • high patient safety due to the automatic alarm function

The METALYZER has been developed and validated over many years.  The Engineering team at Cortex-Medical really understands the demands of CPET in the field and lab.  The practical benefits include:

  • Long calibration times – See brochure below
  • Ability to swap sample lines mid-test
  • Reusable or Disposable Turbines
  • ‘New’ Canopy Interface
  • Full integration with CUSTOMED ECG Systems to allow control of and results of the CPX testing in either software.
  • Full integration with PhysioFlow for non-invasive cardiac output monitoring.  The Physioflow is controlled from the Cortex-Medical METASOFT STUDIO Software.  The cardiac output results are displayed within the Cortex METASOFT STUDIO CPET report.
  • Can be used interchangeably with the CORTEX METAMAX and CORTEX METACONTROL 3000
