The Atmotube Pro 2 is a meaningful step up from its predecessor, adding a carbon dioxide sensor and sharpening sensor accuracy. Reviewers noted it measures PM2.5, NOx, and TVOC with high correlation to reference standards, though some users reported problems with CO2 calibration. GPS and USB-C data access make it more useful for field research and personal monitoring. It does well on outdoor exposure tracking and data collection, while the carbon dioxide sensor's reliability remains a concern for some users. Researchers and health-conscious individuals who want comprehensive air quality data are the fit, but anyone who requires highly accurate CO2 measurements should look elsewhere.
- — Includes carbon dioxide sensor (Sensirion STCC4) for indoor air quality monitoring
