UMEx 200 Passive Sampler for Sulfur Dioxide and Nitrogen Dioxide, 10Pk

Part Number:

500-200

Limited Shelf Life

Overview

UMEx 200 Passive Sampler, for sulfur dioxide and nitrogen dioxide, with validated concentration range of 0.4 to 8 ppm for SO2 and 0.05 to 8 ppm for NO2; single use only.

Details

The single-use SKC UMEx 200 Passive Sampler effectively collects sulfur dioxide (SO2) at a sampling rate of 15.2 ml/min and/or nitrogen dioxide (NO2) at 17.3 ml/min. The sample medium (tape treated with triethanolamine [TEA]) and a "blank" section of tape are contained in one sampler saving time and money. The lightweight UMEx 200 contains the sample medium (tape treated with triethanolamine [TEA]) and clips in the breathing zone for easy occupational sampling. Samplers are provided in individual aluminized pouches that can be used to transport the sampler to a laboratory. The label on the outside of each pouch contains the shelf-life date for easy inventory management. Other UMEx Passive Samplers Available The same convenient and economical UMEx design is also available for sampling formaldehyde/other aldehydes (UMEx 100), ammonia (UMEx 300) and amines (UMEx 400).
