AirSentry® II Mobile Airborne Molecular Contamination Detection System

AirSentry® II Mobile Airborne Molecular Contamination Detection System

Designed to enhance fixed Airborne Molecular Contamination (AMC) monitoring programs, the AirSentry II Mobile AMC Detection System is the first truly mobile system for monitoring airborne molecular contamination in cleanrooms. Mobility plays an important part in a strategic airborne molecular contamination monitoring program, allowing contamination sources to be quickly located, quantified and eliminated.

AirSentry® II  Multi-point Airborne Molecular Contamination Monitoring System

AirSentry® II Multi-point Airborne Molecular Contamination Monitoring System

The most advanced airborne molecular contamination (AMC) monitor available, utilizing sensitive and responsive ion mobility spectrometry to detect and characterize airborne molecular contamination from multiple locations within a cleanroom. The system features a 16- or 30-point manifold sampling system and an on-board computer with secure software and communications.

AirSentry® II  Point-of-Use Ion Airborne Molecular Contamination Mobility Spectrometer

AirSentry® II Point-of-Use Ion Airborne Molecular Contamination Mobility Spectrometer

With parts-per-trillion (ppt) sensitivity, these point-of-use sensors provide fast response, increased detection selectivity and repeatable performance. Combining Air Sentry II sensors with a central software platform allows for easy data acquisition and analysis. The AirSentry II family of airborne molecular contamination sensors provide continuous actionable data, to enable efficient response to contamination sources and events.
