Measuring Odour

There are a number of different ways of measuring odour depending on the odour, source, budget available and on the purpose for measuring. You can measure the emissions - in other words the level of odour emitted at the source, or immissions - the level of odour detected at a specific point or points away from the source as it disperses. You can also measure as a one-off or continuously to monitor any changes over time.

The information below explains some of the measuring methods available, how to carry out the techniques and their applications. The icons to the left indicate at a glance, which can be used to measure emissions, immissions or either.
