Ambient Particulate Monitor APDA-375A (PM2.5)
Overview
Ambient Particulate Monitor APDA-375A automatically measures PM2.5 which is ambient particulate matter of 2.5 μm or smaller in particle diameter. APDA-375A continuously measures concentration levels of PM2.5 by means of beta ray attenuation principle. The long lasting PTFE filter tape has unique strudture, and it is capable of picking samples for chemical component analysis of the particles as well as measuring concentration levels.
Features
Long term unattended remote operation of up to 60 days.
Automatic hourly zero checks.
- Data retrieval through RS-232 serial ports using direct PC connections, modems, printer, or digital data collection systems (Option)
- Direct data logging into CompactFlashTM Card is optionally available.
