SKC Thoracic Parallel Particle Impactor (PPI) Samplers are similar to traditional 37-mm filter cassettes in that they collect dust on standard 37-mm filters. That’s where the similarity ends! The impaction-based PPI Samplers are designed to provide a precise match to the ISO 7708/CEN criteria in a unique way.
Features
- Collection efficiency precisely matches ISO 7708/CEN size-selection criteria
- Operate at 2 L/min for optimal sampling of metalworking fluids by NIOSH Method 5524 and thoracic TLV sampling of cotton dust or hard metals containing cobalt (Co) and tungsten carbide as Co
- Conductive aluminum
- Disposable PPI models are available
