Breath carbon monoxide monitor: PDD-301/sco and PDD-301/rco

The device ensures the measurement of breath carbon monoxide concentration
It is inevitable in the smoking cessation program
  • Monitoring and follow up of breath carbon monoxide concentration
  • Side stream gas analysis for higher accuracy and shorter response time
  • Full flow and volume monitoring during CO analysis
  • CO concentration range: 0 - 100 ppm
  • Automatic zero setting and calibration
  • Combination with a full feature spirometer and/or rhinomanometer

The PinkFlow* flow-meter and the spirometer fully complies with the specifications and requirements of the Standardization of Lung Function Testing ATS/ERS Task force (European Respiratory Journal 2005)

Connecting to a laptop PC provides full portability in battery mode as well
