Parallel Particle Impactor (PPI), Respirable, Aluminum, 2 L/min
Parallel Particle Impactor (PPI), Respirable, Aluminum, 2 L/min Overview
Parallel Particle Impactor (PPI), aluminum, four stages, for respirable sampling at 2 L/min. The PPI provides the closest match to the entire ISO 7708/CEN respirable or thoracic curves compared to any other sampler available.
Requires substrates, filters, and supports purchased separately
The unique, patented SKC Parallel Particle Impactor (PPI®) Samplers are impaction-based and provide a precise match to ISO/CEN size-selection criteria. Respirable PPI Samplers match ACGIH and the ISO 7708/CEN criteria that is specified in the 2016 OSHA final rule on respirable crystalline silica. SKC PPI Samplers are offered in a choice of flow rates for maximum flexibility in pump options, sample duration, and contaminant concentration. PPI Samplers are available in disposable single-use plastic or reusable aluminum.
