• 0.3 or 0.5 micron sensitivity at 1 cfm
• Counts 2 to 6 sizes simultaneously
• Supports manifold, up to 32 ports
• 4 counting modes
• 209E calculations
• Built-in printer

Royco’s one cfm particle counters are reliable and easy to use. Now we have improved this tradition of performance with MicroAir 300 Series.

The MicroAir 300 Series is available with 0.3 or 0.5 micron sensitivity and 2, 4, 5, or 6 size channels. The built-in printer will print as you work and you can also "smart" print stored count data as counts-per-cubic-foot, total counts, or Fed-Std-209E calculations. Data can be stored with numerical location labels (0–999).

All operational features are accessed from a simple, well organized front panel. An optional programming feature includes the storage of sampling parameters for each location—consult the factory. The counter is lighter, smaller, and quieter than previous one-cfm models.

The MicroAir 300 Series supports the Model A2432 Manifold, which permits the MicroAir 300 Series to automatically sample up to 32 locations.
