Airborne Particle Counter
(For Detecting Particles to 0.1 Micron)

• Features particle sensitivity down to 0.3 or 0.5 microns at 1.0 CFM flow rate
• Available with two, four, five, or six particle size channels
• Performs Fed-Std-209E calculations on all size channels simultaneously
• Sample time is selectable from one second to 24 hours
• Includes memory for 400 count cycles of data
• Built-in printer creates records of counts in several formats
• Includes beeper alarm for easy audible detection of particles throughout your facility

These reliable, easy-to-operate instruments provide the sensitivity to monitor particle counts down to 0.3 microns, enabling you to verify even the most rigorous cleanliness requirements. Multiple size channels give you flexibility to monitor at several particle diameters, using the same particle counter.

A quiet, carbon-free pump provides steady vacuum power at 1.0 CFM for rapid sample times. The built-in printer prints as you work, or 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).

The bright LED display makes reading the data easy and error-free. The display shows particle counts in either cumulative or differential modes, as well as the values from the optional probes for humidity, temperature and air velocity. All operational features are accessed from a simple, well organized front panel. A programming feature includes the storage of sampling parameters for each location.

These features make this the perfect instrument for monitoring cleanroom cleanliness or performing cleanroom certifications.
