Collecteurs d'aérosols pour les compteurs de particules

AVANTAGES

• Cost Effective:
• Most economical monitoring of fixed points at timed intervals; lowest cost per sample location
• Ability to sample much larger area than single particle counter
• Ethernet communications to facility monitoring system
• Flexible:
• Has an easily programmed sampling routine, whether simple or complex sequences
• Automatically changes sampling recipe upon receiving alarm or external signal
• Easily replaces older AM 12/24/30 manifolds
• Has large coverage radius: Each sampling point can be up to 125 feet away
• Rapid and Accurate Measurements:
• Using LASAIR® II's patented flow control, this is the only manifold that properly compensates for manifold pressure drop eliminating systematic particle undercounting of up to 15%
• Maintains constant flow (nominal 3 CFM) at each sample location to minimize gravitational settling
• With isokinetic sampling probes, captures particles at same velocity as sample air, preventing distortion in particle size relationships

• Facility particle monitoring
• Monitoring large minienvironments
• Cleanroom verification and trend analysis

Air sampling at various locations within a cleanroom facility can be performed effectively using an aerosol manifold. There are two methods for using this device. One approach is multiplexing sample air from a number of sample locations into a single particle counter. This procedure offers the most economical way to monitor multiple points at timed intervals.

Another approach is to use a particle sensor that continuously monitors the mixed air from the individual sampling points while using an aerosol manifold and particle counter. When the sensor detects a rise in counts from the mixed air which exceeds a predetermined alarm level, the particle counter will examine each manifold port to locate the problem.

Each manifold can be programmed for single sampling at one location or executed in a user-defined sequence. The aerosol manifolds are designed to achieve a consistent flow rate of 3 CFM at each sample location.

This particle counter is CE certified.
