LFY-712 Dry Dust Debris Analyzer (Particle Release) (Cleanliness - Particle Matter Index Analyzer)

Main purpose/Use 
It is used to evaluate the particle release of textiles, protective clothing, surgical gowns, surgical drapes, clean suits, and non-woven fabrics by measuring the number of dry-state fibers falling off (fiber fall count and cleanliness - particle matter index).
