PK-L2020A Portable Mask Efficiency Comparison Tester
Overview PK-L2020A portable filter tester, for the bulk and inconvenience of most test instruments in the current market, it is not convenient to carry it to customers anytime, anywhere to make a demonstration, resulting in the situation that manufacturers can not better promote their own products, our company carefully developed this high-end Product, this instrument can be used for non-woven filter materials, glass fiber filter materials, new filter materials, filter efficiency, resistance test, and mask tightness test. The test data of the product has been compared and tested by large-scale test equipment of well-known brands at home and abroad, and has high consistency. The product is highly recognized by the experts of the Cleanliness Association and the filter material industry manufacturers. The product system is based on the following standards NIOSH, 42CFR84-2005, EN149: 2001, GB19083-2010, GB / T2626-2019, YY0469-2011, YY / T0969- In 2013, we also designed and manufactured with reference to EN1822, IEST-RP-CC021.1 and other related principles.
