Airy Technology P311’ s large color display shows cumulative and differential particle counts of 3 particle sizes simultaneously. The middle particle range can easily be changed by a user. P311’ s maximum concentration of 4,000,000 particles/ft3 and up to 8,000 data set record capabilities is the highest in the market. Data can be checked on the unit display and/or easily downloaded to your PC via USB cable and saved as a CVS file which is transferable to Excel. P311 is accurate, dependable, user friendly, compact and light weight.
