The short-term diffusive sampler is based on the same principle as the 1-week sampler.

The sampler is suitable for checking compliance with short–term limits for 8 and 24 hours. The main application is idicative measurement of of the 8-hours limit value to identify critical zones and the assessment ofpersonal exposure for epidemiological studies.
