Air Sampling

Air sampling is used to measure an individual’s exposure to a harmful substance in the air such as dust and vapors, which is then compared to an exposure limit. Personal air sampling pumps are used with sampling accessories and media (filters and tubes) to collect the substance, which can then be sent to a laboratory for analysis. This will then give an 8-hour exposure value. Real-time dust monitors are also available to give instantaneous dust levels, which will show when exposure occurred and a dust level in real-time.
