The remote air particle counters of the AeroTrak™ 7000 series have a compact design and modern concept for data backup and transmission for cleanroom monitoring. Secure data download via Ethernet is effectively supported by internal data buffering. Integrated data storage secures up to 3,000 samples. Data integrity is always guaranteed even in the event of local failure conditions in the monitoring environment (e.g. voltage loss to the data acquisition computer or network problems). In combination with the monitoring software FMS 5©, complete reconstruction of particle monitoring data from the AeroTrak data buffer is possible after a data acquisition failure. The AeroTrak™ particle counting system is also equipped with a ModBus interface, providing a standardised software interface that enables data exchange between software applications from different manufacturers.
