All 5 important mass ranges of size TSP, PM10, PM7, PM2.5, and PM1 can be seen as mass mode on the display along with 2 frequently used cumulative particle sizes of > 5.0 and > 0.5 microns in the particle mode.

Customized Mass Conversion

The particle count from 8 ranges in size convert to mass utilizing a proprietary algorithm used for normal density aerosols. Adaptation for special particulates that have different densities can be accomplished with "K�factors" that are user programmable.

Data Interface Flexibility

The Aerocet 531 can store a maximum of 4,000 records for networked datalogging, Excel formatted output, or printer output with your included computer software for a single machine (AeroComm).

Relative Humidity and Temperature Option

This feature is a plug & play option whhich adds relative humidity and ambient temperature capabilities immediately to your logged and displayed data.
