• AC or battery operation
• 0.3 micron at 1.0 cfm (3313)
• 0.5 micron at 1.0 cfm (3315)
• 3-hour battery operation
• 6 particle size channels
• ISO 14644-1 calculations

• Stores 2000 records

Met One’s Model 3313 and Model 3315 deliver a 1.0 cfm (28.3 lpm) sampling rate with either 0.3 micron sensitivity (3313) or 0.5 micron sensitivity (3315). Operating from either AC mains or batteries, the Model 3300 series can provide continuous monitoring of clean areas, storing up to 2000 readings in its memory buffer. The stored data can be reviewed on the front panel, printed, or downloaded to a computer. The built-in printer is standard.

All six channels are displayed simultaneously on the front panel display, plus optional environmental sensor data, such as relative humidity, temperature or air velocity. Alarms can be set for all measurements. The operator can review stored records by using the scrollable display.

Both ISO 14644-1 and Federal Standard 209E calculation modes are included, allowing stored data to be analyzed according to either standard. The enclosure can be either aluminum for lightness (less than 16 pounds or 8 kilograms) or stainless steel for environmental and chemical compatibility.

The Model 3313 and Model 3315 from Met One are full-featured 1.0 cfm airborne counters that offers one important difference – portability as a battery-operated instrument. With the Model 3300 series, you can "cut the cord" without losing features!
