LFY-712 dry flocculation tester (Particle release) (cleanliness-particulate matter index tester)
The main purpose
It is used to measure textile, protective clothing, surgical sheets, surgical gowns, clean clothing, non-woven fabrics, and evaluate the particle release of products based on the amount of dry floc (floc number and cleanliness - particulate matter index).
