This monitor utilizes two tapered element oscillating microbalances (TEOM) and two Filter Dynamics Measurement Systems (FDMS), which account for volatile and nonvolatile PM fractions.<\/p>\n<p><strong>Description<\/strong><\/p>\n<p>The 1405-DF TEOM Monitor simultaneously measures PM Fine (PM-2.5), PM Coarse and PM-10 mass concentrations. Consisting of two Filter Dynamics Measurement Systems (FDMS) and two TEOM mass sensors housed in a single-cabinet, network-ready configuration that includes control system with touch-screen user interface. The TEOM 1405-DF distinguishes itself from other PM measurement methods by utilizing a direct mass measurement that is not subject to measurement uncertainties found in surrogate techniques. It provides a self-referencing, NIST-traceable true mass measurement.<\/p>\n<p><strong>Key Features<\/strong><\/p>\n<ul>\n<li>Design that meets US and International Particulate Monitoring Regulations<\/li>\n<li>Compact, stand alone unit which utilizes a virtual impactor to measure PM Fine (PM-2.5) and PM Coarse concentrations with the ability to output PM-10<\/li>\n<li>Touch-screen GUI interface quickly and intuitively accesses system status, TEOM data, settings, and instrument conditions<\/li>\n<li>Service screen provides access to software wizards which walk the user through
