Met One Aerocet-531S Mass Particle Counter/Dust Monitor
Particle Mass Profiler and Counter in a Single Handheld Unit
The Aerocet 531S is a small, handheld, battery operated, and completely portable unit. This unit provides particle counts or mass PM measurements as stored datalogged values, real-time networked data, or printed results.
Six Mass Ranges and Four Particle Sizes
Six important mass size ranges (PM1, PM2.5, PM4, PM7, PM10, and TSP) are displayed in mass mode as well as four popular cumulative particle sizes (> 0.5, 1.0, 5.0 and10.0 microns) in count mode.
Tailored Mass Conversion
The particle counts from eight size ranges are converted to mass using a proprietary algorithm for typical-density aerosols. Accommodation for special particulate with different densities is provided through user-programmable "K-factors."
Flexible Data Interfaces
The Aerocet 531S stores up to 6,257 records. These records can be viewed on the display, or transferred to a computer via USB or RS232. Our included Comet download utility makes file transfers easy. Data files can easily be imported into an Excel ® formatted output.
Temperature and Relative Humidity Option
A plug-and-play option that immediately adds ambient temperature and relative humidity capabilities to the displayed and logged data.
