EPAS is the only instrument on the market to offer true simultaneous monitoring of PM10 and PM2.5. EPAS is available in two kits: Basic and build your own (Foundation). Both offer the ability to configure with different toxic chemical sensors, size-selective impactors, and EPAS-specific meters to simultaneously measure up to 14 critical air parameters. Several wireless and networking options are available as well as datalogging capabilities. Graphing and reporting software is compatible with PC and Mac.
