Unit VI Assessment#2 Particulate Matter Monitors Essay

Unit VI Assessment#2 Particulate Matter Monitors - Essay Example Working Principle: This monitor is an example of a high speed counter with a resolution of 1 count/liter. The monitor collects aerosols on a removable 47 mm Teflon filter allowing for future analysis. The particulate monitor can also analyze aerosols using 1.177 GRIMM Software program on a computer screen. The monitor has a random sampling head for collecting particles and leading them directly into an optical chamber that has a laser. The chamber counts each particle and classifies them by size. The concentration of the particles relates to the duration of collection. The monitor can also give results continuously up to one minute intervals (Peters, Ott, & Patrick, 2006).  Ã‚   Key Features:   The Model 1.108 can conduct real-time monitoring and the same times analyze the particles later. The monitor can measure particle size ranges from 0.30  µm to 20  µm and can auto zeros and self-diagnose itself. The monitor has software that is fully compatible with most Windows operating systems Peters, M., Ott, D., & Patrick, T. (2006).
