Carbon Monoxide CO

Carbon monoxide (CO) is a colourless, odorless, and extremely toxic gas commonly produced by the incomplete combustion of carbon-containing materials. It poses significant health risks and is a key target for emissions monitoring in many industries. Accurate and reliable measurement of CO levels is critical for safety, environmental compliance, and operational optimisation.

At Signal Group, our carbon monoxide analysers are engineered for precise detection and continuous monitoring, providing crucial data that helps businesses comply with safety standards and environmental regulations while improving process efficiency.


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.
