UMEx 200 Passive Sampler for Nitrogen Dioxide/Sulfur Dioxide

Using the same chemistry as active OSHA Method ID-182, the UMEx 200 Passive Sampler collects sulfur dioxide (SO2) at 15.2 ml/min and nitrogen dioxide (NO2) at 17.3 ml/min for 15 minutes to 24 hours. The UMEx 200 contains both the sampling tape treated with triethanolamine (TEA) and a separated "blank" tape section all in one sampler, saving you money. Samples are stable for up to three weeks at ambient temperature.
