Carbon Dioxide CO₂

Carbon dioxide (CO₂) is one of the most significant greenhouse gases managed by industries worldwide, due to its impact on climate change and its role as a byproduct in various manufacturing processes. Monitoring CO₂ emissions is not only crucial for compliance with global environmental regulations but also for operational efficiency and sustainability initiatives.

At Signal Group, we design and manufacture advanced gas analysers that deliver reliable and continuous monitoring of carbon dioxide emissions. Our CO₂ analysers are engineered with precision, making them ideal for a wide range of applications, from industrial emissions control to environmental monitoring.


Non Dispersive Infrared (NDIR) Multi-gas analysers are available in 1, 2, 3, 4 or 5 gas channel configurations, offering high levels of performance and flexibility. Options include CO, CO2, CH4, NO, N2O, SO2, HCl and O2.
