Aerocet-531 Mass Particle Counter/ Dust Monitor

2-in-1 performance!

Particle Mass Profiler and Counter in a Single
Handheld Unit
The Aerocet 531 is a small, handheld, battery operated, and completely portable unit. This unit provides both particle counts or mass PM measurements as stored datalogged values, real-time networked data, or printed results.

Five Mass Ranges and Two Particle Sizes
All five important mass size ranges ( PM1, PM2.5, PM7, PM10, and TSP) are displayed in mass mode as well as two popular cumulative particle sizes ( > 0.5 and > 5.0 microns) in particle 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 531 stores up to 4, 000 records for printer output, Excel® formatted output, or networked datalogging through the included single computer software ( AeroComm) .

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.

Specifications
OPERATING PRINCIPLE Counts individual particles using scattered laser light and calculates the equivalent mass concentration using a proprietary algorithm
