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 points at 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 settling by maintaining a steady flow (nominal 3 CFM) at each sample point
- Distortion in particle size relationships is 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 the Pharmaceutical Net or Facility Net software
- Programmable recipes and sample point sequences
- Assembly designed to remove contamination from the valves
- Alarm for low vacuum; automatic shut-off for pump overheating
Applications
- Facility monitoring
- Monitoring large mini-environments
- Cleanroom verification and trend analysis
