    • Embodiments of the invention generally related to a method and apparatus for scanning a v-bank filter. In one embodiment, a method for testing a v-bank filter includes providing an aerosol challenge to an upstream side of a v-bank filter, scanning a downstream side of the v-bank filter with a probe having one or more rectangular sample ports, and providing samples taken through the probe during scanning to a test instrument. In yet another embodiment, a probe for scanning a v-bank filter is provided that includes a body having a plurality of rectangular sample ports. Each sample port is tapered to a port configured to connect to a sample tube. The long sides of the rectangular sample ports are arranged in a stacked parallel orientation.
    • 本发明的实施例一般涉及一种用于扫描v-bank过滤器的方法和装置。 在一个实施例中,一种用于测试v-bank过滤器的方法包括向v-bank过滤器的上游侧提供气溶胶挑战,用具有一个或多个矩形采样端口的探头扫描v-bank过滤器的下游侧, 并在扫描期间将通过探头的样品提供给测试仪器。 在另一个实施例中,提供了一种用于扫描v族滤波器的探针,其包括具有多个矩形采样端口的主体。 每个样品端口逐渐变细到配置为连接到样品管的端口。 矩形样品端口的长边以堆叠的平行取向布置。
