Microdust Pro particulate monitor

The Microdust Pro particulate monitor assesses concentrations of suspended matter over the range of 1µg/m3 to 2,500 mg/m3. Using near-forward light-scattering technology, it is suitable for tracking airborne microscopic particles, including dust, dirt, soot, mold spores, smoke and liquid droplets, in industrial hygiene, indoor air quality, and workplace exposure investigations. Its narrow scatter range of only 12–20 deg. minimizes uncertainty caused by particle color, shape and refractive index. Average, spot, and minimum or maximum concentrations can be recorded over user-defined intervals ranging from 2 s to 10 min, and an internal logger stores up to 15,700 data points over 32 separate runs. The device displays variations in dust concentration using a real-time scrolling graph on a liquid crystal display (LCD) screen. Data can be easily downloaded to a personal computer or printer using an RS-232 interface cable. The Microdust Pro comes with WinDustPro Windows-based software, which lets users create an instrument profile for specific repetitive tasks, as well as data recovery, production of history-based line-graphs, and development of tables and reports. An optical calibration filter allows the user to restore the instrument to its as-delivered condition at any time in the field.
