Serinus® 31

Carbon Dioxide (CO2) analyser

The higher proliferation of Carbon dioxide is a critical factor to the increasing global warming. The Serinus® 31 carbon dioxide (CO2) analyser uses non-dispersive infrared (IR) gas correlation spectroscopy to provide accurate, stable, and repeatable measurements of gaseous CO2. It is a trusted tool for global governments and industries to measure the precise levels of Carbon dioxide, enabling them to make informed decisions and contain their carbon footprint.

Superior air quality monitoring for global environments

Air quality monitoring is increasingly important in today’s urban, industrial and rural areas. The Serinus® range of analysers has emerged through 40+ years of experience and knowledge gained from operating large air quality monitoring networks. The result is a superior portfolio of instruments that integrate seamlessly into continuous monitoring networks. They not only measure human exposure to pollutants but can be combined with trace/background monitoring as well as stack monitoring – thus becoming a vital tool for governments and organisations to track and abate air pollution and its effects on their immediate environment.
