Odour Monitoring and Control


Gas Data offer several odour monitoring solutions. Industrial-scale biological processes can produce hydrogen sulphide (H2S) levels of hundreds of parts per million. However, any escaping gas will usually rapidly disperse in the air. If large quantities are allowed to escape into the environment, however, they can cause health hazards to workers and neighbours.

This will lead to the Environment Agency investigating the site. The best way to solve such problems is to know exactly where and when the H2S is being produced. The legal occupational exposure limits for hydrogen sulphide are ten parts per million averaged over eight hours, or fifteen parts per million over fifteen minutes.

The portable GFM 406 can be configured to measure hydrogen sulphide levels and act as a mobile detector. Alternatively, if the location of the H2S is known but the timing or quantity of gas releases is not, then either a Click! System or the Odour Control System provide continual and accurate monitoring.

The human nose can detect hydrogen sulphide from concentrations above a fraction of a part per million, and stops being able to detect it above about 200 parts per million. Gas Data provide clients with the equipment to keep H2S levels safe.
