Sulphur Dioxide (SO2) Detectors

We offer a wide selection of sulphur dioxide gas detectors from leading global manufacturers including BW, Crowcon, Dräger, GMI, Green Instruments, Honeywell, MSA, RAE Systems, Riken Keiki, Senko, and Uniphos. These solutions deliver accurate, real-time monitoring, early warning of leaks, and reliable performance in challenging environments.

Industries such as oil and gas, power generation, pulp and paper, metal refining, and shipping face particular risks from sulphur dioxide emissions. Effective SO2 detection systems are critical to protect workers, ensure compliance with environmental regulations, and prevent costly incidents.

Sulphur Dioxide (SO2) is a toxic, corrosive gas widely produced by fossil fuel combustion, metal smelting, and chemical processing. It is known for its sharp, irritating odour and poses significant risks to both human health and the environment. Exposure can cause severe respiratory issues, eye irritation, and long-term health problems, making reliable detection and monitoring essential in industrial operations.
