UMEx 200 Passive Sampler for SO2/NO2

The lightweight UMEx 200 clips in the breathing zone for easy personal sampling. The sample medium (tape treated with triethanolamine [TEA]) and a "blank/correction" section of tape are contained in one sampler saving time and money. Samplers are provided in individual aluminiumised 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.
