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.

A local touch PC on the mobile cart provides instant feedback of AMC levels at each monitoring location. Facility Net software provides data storage and graphical displays in real-time while monitoring the specific environment.

Onboard, chemically filtered, clean dry air (CDA) and vacuum are supplied within the cart enclosure to ensure that the analyzers can sample immediately upon relocation without long analyzer warm-up times incurred by competitive systems.
