The Aerocet 531S 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, PM4, 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 531S 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.
