Cortex MetaLyzer

Measuring at Various Locations

The entire system is portable and light weight making it accessible in various locations and enabling one to perform measurements from anywhere.

  • Humidity: 0 to 99%
  • Temperature: 50° to 95° F (10° to 35° C)
  • Operating time with external battery: 8.5 Hours

Greater Convenience with Bluetooth Smart

The integrated Bluetooth Smart technology allows you to easily and quickly connect MetaLyzer to wireless peripheral devices. Measuring the heart rate, for example, using the Polar H7 strap, gives a completely new dimension to the process as regards range and security of data transmission. 




The application software MetaSoft Studio is the basis of all Cortex systems and of prime importance for data acquisition and data analysis. The software manages and monitors all spiroergometric processes and controls the peripheral systems, such as the ergometers and the heart rate and blood pressure measuring devices.
