Carbon Monoxide (CO) Gas Detection Systems & Alarms

Here at Gas Alarm Systems, we provide a full suite of carbon monoxide detectors and alarms specifically designed to excel in commercial and industrial environments, so you and your employees can enjoy complete peace of mind.


Carbon Dioxide (CO2) Gas Detection Systems & Alarms

Our carbon dioxide alarms and detectors have been designed with a finely-tuned sensitivity that allows them to quickly and easily distinguish the difference between safe and unsafe levels of CO2. The gas isn’t flammable and it’s not combustible, but our CO2 detection systems can help protect employees from the risk it poses at higher concentrations.

Methane Gas Detection Systems & Alarms

Our methane gas detection systems are instrumental across a broad range of industries for detecting unsafe levels of methane, a widespread and potentially dangerous type of natural gas. It poses a number of foreseeable risks to human health and safety – not only can it be toxic in high enough quantities, but it’s also highly flammable, opening up the risk of deadly explosions.
