Mobile ergospirometry system K4 b2

The K4b2 is the first portable system for pulmonary gas exchange measurement with true breath-by-breath analysis. Its technology and dimensions allow the user to measure physiological response to exercise without limitations. With more than 20 years of experience in mobile VO2 testing, K4b2 is the most accurate and reliable device under any conditions. The K4b2 has been validated, used and mentioned in more than 600 publications worldwide including the most prestigious scientific journals. The K4b2 provides unsurpassed versatility. Whether in the lab or in the field, tests can be carried out in three different configurations: Holter Data Recorder, Telemetry Transmission and Laboratory Station. The K4b2 is provided with integrated GPS for speed, distance, altitude and position measurements, which are synchronized with Gas Exchange Data.
