AirSentry® II AMC Monitoring System

Monitors up to 30 sample locations

The AirSentry II AMC Monitoring System is the most advanced Airborne Molecular Contamination monitor available, utilizing state-of-the-art gas detection technology (Ion Mobility Spectrometry, Pulsed Fluorescence) to detect and characterize airborne molecular contamination from multiple locations within a cleanroom. This system contains a 16- or 30-point manifold sampling system and a laptop computer with secure software and communications, and can be configured to detect one or more compounds. In modern cleanrooms, processes and equipment are often spread over a large manufacturing area and multiple floors.

Air handlers recirculate the majority of air within a cleanroom and easily spread molecular contamination to unwanted areas, negatively impacting areas far away from the actual contamination source. The AirSentry II AMC Monitoring System provides a central monitoring station that allows for rapid contamination detection and analysis, as well as customizable AMC monitoring strategies to cover a wide number of sample points spread across a facility.
