radiello® is the ideal passive sampler for indoor vapor intrusion environments because of its high sampling rates, high capacity, and low detection limits. It is versatile for sampling from 15 min for STEL sampling and 8 hrs for TWA sampling to 7-30 days depending on the sampling environment.

Like other passive samplers, there are limitations to sample vapor intrusion or soil gases such as in micro-wells and like environments. radiello® is suitable for sampling in crawl spaces and indoor air environments to the surrounding outdoor environment. In addition to samplers for VOCs, radiello® samplers are available for sampling a wide range of compounds such as: aldehydes, hydrogen sulfide, ammonia, nitrogen and sulfur dioxides, phenols, ozone, hydrochloric acid and anesthetic gases.
