This holder with inertial impactor is a filter sampling unit with a PM4 inertial impactor attached.
\nThe filter sizes are dia. 25 mm and dia. 35 mm.
\nIn this design, particles first collect on a sample plate. Respirable particles that penetrate the plate then collect on a glass fiber filter.
\nThis can be used to measure dust in work environments, and to sample manganese etc.
\n\u2022 The particle size separator is certified by the Japan Association for Working Environment Measurement. <\/p>\n
\u25cf This holder can collect PM4 respirable particles (with a 50 % cut at 4 \u03bcm) at a suction flowrate of 20 L\/min.
\n\u25cf This particle size separator is compliant with the regulatory conditions in article 2 item 2 of the Work Environment Measurement Standards.
\n\u25cf It can be used to sample dust designated for collection as respirable particles in the Work Environment Measurement Standards as well as manganese etc.<\/p>\n","protected":false},"excerpt":{"rendered":"
