Introducing an aerosol particulate monitor with increased functionality! The 531 combines hand-held portability with highly precise measurements, and can be configured as either a particle counter or particulate mass monitor.
Using a laser-diode-based optical sensor, the 531 uses light scatter technology to detect, size, and count particles (larger than 0.5 microns). This detected information can be converted into particle mass using mass-density conversion factors, or may be displayed as particles per size range, depending on how the 531 is configured.
A Remarkably Flexible, Higher Performance Instrument Featuring:
Operates as either a particle counter, or mass monitor.
Two channel particle counter
PM1, PM2.5, PM 7, and PM10 Mass Ranges
Air Quality Surverys
IAQ Source Troubleshooting
Work Place Monitoring
The 531 operates uniquely from any other instrument, and functions in one of two modes. As a mass par ticulate monitor, particles are detected, sized, and counted in multiple size ranges. Mass conversion is made using standard conversion factors, or by using user-programmable
factors based on unique conditions. The particle mass can be display as PM1, PM2.5, PM 7, or PM10. When configured as a particle counter, sized-based particle counts are displayed as cumulative (counts above threshold) above 0.5 and 5.0 microns, the two most popular size ranges.
