• Battery-operated portable
• 0.3 or 0.5 micron sensitivity at 0.1 cfm
• Counts 2 to 6 sizes simultaneously
• 4 counting modes
• Built-in printer

In the past, if you wanted six size channels or printer capabilities, you had to contend with a large, heavy counter or with external printers, cables, and cords. Now, with a breakthrough in design, Royco gives you battery-operated portability, up to six size channels, and a built-in printer that prints count results on the fly—all in one compact instrument!

The MicroAir 330 Series counts airborne particles in up to six different size ranges simultaneously. Count data is displayed on the front-panel as total number of particles (cumulative count) or the particles in each size range (differential count). The printout shows cumulative and differential count data for each size range.

For maximum flexibility, four modes have been incorporated to provide quick answers to measurement questions or allow unattended operation. The manual mode completes one count cycle then turns the air pump off to prolong battery life. Auto mode repeats the count cycle for the number of cycles programmed to allow unattended monitoring. Concentration mode gives a quick estimate (within seconds) of the particle concentration. Beep mode provides one beep after the count exceeds a selected limit, which is handy for isolating sources of particle contamination such as leaks in filter banks.
