Cost-Effective AM II-16/32 for Aerosol Monitoring
With a fixed particle counter, the AM II manifold provides sophisticated features for sequentially monitoring aerosol contamination at several locations. When ongoing monitoring is not required, the AM II is perfect for trend analysis and cleanroom verification.

Compatibility
Lasair® II or Lasair III particle counters, or IsoAir® PLUS particle sensor
Benefits
Cost Effective
Cost-effective monitoring of fixed pointsat timed intervals
Minimal cost per sample location
More expansive monitoring area compared to a stationary particle counter
Communication via Ethernet to the facility monitoring system
Flexibility
Programs a sampling routine easily for both simple and complex sequences
Alters sampling recipe automatically upon receiving an external signal or alarm
Large coverage area: every sample point can be up to 125 feet away
Accurate and Rapid Measurements
Patented flow control ensures that the manifold compensates for manifold pressure drop, removing systematic particle undercounting of up to 15 %
Reduces gravitational particle settlingby maintaining a steady flow (nominal 3 CFM) at each sample point
Distortion in particle size relationshipsis prevented using isokinetic sampling probes, which collect particles at the same velocity as sample air
Features
Multiplex monitoring of up to 32 sites using a single particle counter
Managed by thePharmaceutical Net orFacility Net software
Programmable recipes and sample point sequences
Assembly designed to remove contaminationfrom the valves
Alarm for low vacuum; automatic shut-off for pump overheating
Applications
Facility monitoring
Monitoring large mini-environments
Cleanroom verification and trend analysis
