METAMAX 3B Mobile CPET System



Cortex METAMAX 3B Mobile CPET System

The METAMAX 3B CPET can be operated using a laptop, the Smart Control tablet, or completely autonomously for the device itself. To determine the velocity and location of a participant in a field test, the METAMAX 3B CPET System uses a powerful GPS module. This GPS module allows you to calculate velocity and altitude changes to provide an overview of the stress factors experienced by the participant during a field test.

Whether in snow and ice or at temperatures below -10°C, or in the desert at temperatures up to 40°C, the METAMAX 3B is insensitive to extreme environmental temperatures.

The METAMAX is the ultimate in mobile CPET/CPX systems.

  • Ultralight, mobile Breath-by-Breath system (580 g)
  • Designed for outdoor performance diagnostics
  • Insensitive to extreme environment conditions- altitude, temperature, humidity & movement.    
  • Telemetric range of over 1,000m (bi-directional telemetry with Bluetooth technology)
  • Chest and back carrying system
  • Convenient control via Smart Control, laptop or as stand-alone
  • 6-hour battery life
  • 400 hours data storage
  • Constant dynamic flow control
  • Flexible audio signals
  • METASOFT STUDIO Software for the ultimate flexibility

New: Swim Option for METAMAX 3B CPET

The MetaMax has been developed and validated over many years.  The Engineering team at Cortex-Medical really understand 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
  • 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 METALYZER and METACONTROL 3000

German astronaut Alexander Gerst will start his space mission on the ISS in Summer 2018. This is the first time a mobile spiroergometry device will be in space. Over six months, Alexander Gerst will use the METAMAX 3B to further determine the impact of the space journey on the human body. Being in orbit, the fitness changes and the journey back to earth is often more exhausting than the beginning.

The project which is accompanied by the Institute of Aerospace of the TU Dresden is not just about assessing astronaut’s fitness level. The results of the experiment will help to optimally prepare future space tourists on their flight into space.


Whether in snow and ice at temperatures of down to 10 ° C below zero, or in the desert at temperatures up to 40 ° C, the METAMAX® 3B calibrates extreme outside temperatures.


With a weight of just under 600 g, the METAMAX® 3B is the lightest mobile spiroergometer on the market. This decisive advantage in many disciplines, because in field tests, the total weight of the subject increases only minimally and has little influence on your test results. Children’s Harness also available


The real workload on firefighters in action is difficult to simulate in the lab. When heat, stress, respiratory protection, high weight of the equipment and other effects come together, it is particularly important to measure their influence on the subject in combination.
