Carbon monoxide (CO)

Invisible risk for man and machine

Carbon monoxide (CO) is a colorless, odorless and tasteless gas that is produced during incomplete combustion of carbon-containing materials such as wood, coal, oil or gas. It is one of the most dangerous respiratory toxins of all – and also poses an explosive risk. Without professional CO gas detectors, carbon monoxide usually goes unnoticed – with potentially life-threatening consequences.

Danger from carbon monoxide – toxic & flammable at the same time

CO is primarily known for its high toxicity: Just a few hundred ppm can lead to unconsciousness or death. Less well known, but relevant to safety: Carbon monoxide is also flammable and can form explosive mixtures with air – especially in enclosed spaces or technical systems.

Safety-relevant properties of CO:

Explosion limit range: approx. 12.5 – 74 % by volume
Ignition temperature: approx. 605°C
Flash point: not defined (gas)
Gas density: similar to air – even distribution in the room

Despite the relatively high lower explosion limit value (LEL), in practice the focus is usually on protection against poisoning. Carbon monoxide can cause damage to health from as little as 30 ppm – especially in poorly ventilated areas.

Why CO gas detectors are indispensable

Carbon monoxide cannot be detected without technology. This is why early warning using reliable gas detection technology is essential to protect human life.

Your benefits with our carbon monoxide gas detectors:

Early detection from just a few ppm
Reliable personal protection in rooms with combustion processes
Ex alarm for CO recirculation or system leaks
Combination devices for toxic & flammable gases in one system
Standard-compliant & certified solutions for all industries

Typical areas of application for CO gas detection:

Heating systems, boiler rooms, burner systems
Underground garages, vehicle halls, workshops
Industrial processes with CO generation or recirculation
CHP, biomass power plants, thermal utilization plants
Wood processing, metalworks, glass production
Research laboratories, test benches, universities

Whether targeted CO use or unintentional leakage: in all cases, a gas warning system for carbon monoxide is a central component of any professional safety concept.

Conclusion: Recognize CO – before it’s too late

Carbon monoxide is silent, invisible – and deadly. Even at low concentrations it causes poisoning; at higher concentrations it is even flammable. Due to its physical properties, CO is one of the most dangerous industrial and household gases.

Our certified CO gas detectors protect your employees, technology and infrastructure – reliably, durably and tailored to your specific requirements.
