Page 7: Product Overview
Product Overview The LV-250R is a PM2.5 sampler. It is capable of mass concentration measurements of particulate matter (PM2.5) using a filter, based on the interim measurement manual designated by the Japanese Ministry of the Environment. With this sampler, airborne particulates in environmental air are sucked in at a constant flow rate via a suction port. -
