DAS is robust and can scale from a single station installation to a nation-wide installation of hundreds of stations. Implement DAS for Stack and Ambient Air monitoring within Power Plants, Steel Plants, Cement Plants etc. Nationwide network for Stack and Ambient Air monitoring, City wide pollution monitoring, Indoor air quality monitoring

Data Acquisition: DAS can collect data from multiple gas analyzers, SPM analyzers, Dust monitors and weather stations at single or multiple locations. All data are collected on DAS web server and is accessible to clients from anywhere, anytime, 24×7; clients use a standard browser on PC / tablet / cell phone..

Reports & Charts: DAS can generate hierarchical tree view of all sites at a glance, It has dashboard showing comprehensive information of air quality in and around a plant, with real-time data trends and values, historical data average, min, max – values and trends with user defined interval (5 / 10 / 30 / 60 minutes, daily etc.)

Alarms and data flags: DAS defines alarm limits as well as various flags, and sends alerts by SMS, email, alarm history.
Reports & Charts: DAS generates standard reports in MoEF stipulated formats, where, one can view daily and monthly environment report, average tabular report, single station and multi-station report. It has robust reporting engine for development of custom reports, automatic report scheduling and delivery by email / print. Reports are displayed in form of charts, Wind rose / Poll Rose, Frequency analysis, Perspective bar and line charts.
