1 Ambient Air Monitoring Systems ECM ambient air monitoring systems are integrated in air conditioned thermal isolated light weight shelters allowing stationary and mobile installations. The usually monitored gaseous pollutants are: SO2 H2S CxHy NOx TRS PAH O3 NH3 HF CO VOC Automated Ambient Air Mercury Analyzer Long-term mercury analysis with unmatched accuracy, sensitivity, and reliability. Key features: Low detection limit < 0.1 ng/m3 Internal permeation source for automated calibrations Dual channel gold trapping for uninterrupted sampling Low operation costs

2 Aerosols are monitored in accordance to TSP, PM10, PM2,5 or PM1 standards. Simultaneous monitoring and sampling of different fractions. Certified dual channel beta gauge particle monitor coupled to a certified sampler and an 8 channel OPC with continuous reading of aerosol concentrations. Sampler products allow to take aerosol sample or later analysis for heavy metals and other pollutants. RackMount Model AE22 The Aethalometer TM is the world leading method of measuring black carbon (BC) or elemental carbon (EC) particles in air. The Aethalometer is an instrument that uses a continuous filtration and optical transmission technique to measure the concentration of BC in near-real-time.

3 The only commercially available field deployable OC/EC analyzer with true laser-based pyrolysis correction and compatibility with accepted NIOSH 5040 methods. Ultrafine particle monitor TSI Provides continuous Ultra-fine Particle (UFP) size distribution and number concentration data for long-term, air quality monitoring. Features and Benefits: Long-term, unattended operation Size distribution from 20nm 1,000 nm Low start-up and operating costs No working fluids; radioactive source Convenient data management with remote access via the Internet Continuous measurements Optional environmental sampling system Compact TSP, PM10, PM4, PM2,5 PM1 instrument to monitor all of the fractions in parallel. Particle counter / sizer allowing to define 16 size channels showing particle count and mass concentration both.

4 Optical Particle Sizer 3330 Product Details Optical Particle Sizer 3330 (OPS) is a light, portable unit that provides fast and accurate measurement of particle concentration and particle size distribution using single particle counting technology. Backed by over 40 years of aerosol instrumentation design experience, the OPS uses state-of-the-art optics with 120 light collection and sophisticated electronics processing resulting in precision, high quality data. Rigorous factory calibration standards ensure measurement accuracy. The Model 3330 particle sizers can be used alone, or it can be placed in TSI s weatherproof Environmental Enclosure. Online monitoring of heavy metals in ambient dust

5 Compact ambient air monitoring station SO2, NOx, NO2, O3, CO, CO2, VOC, PM10/ 2,5/1 Auto Handler for Dust Filter Weighing Complete solution coupling Filter Weighing System with weighing automation. The unit and weighs each filter according to administrator selected instructions. Each filter's bar code is read. It is then taken to the balance where it is inserted and placed on the balance pan in the exact came position each time Weighing time: 3 min per filter using direct read. AH225 performs automated static discharge.

6 ECM AIR ECM AIR is an ambient air monitoring data systems providing data collection, archiving and presentation in accordance to EU regulations. The architecture is a client / server one allowing web server functions. Data can be presented in graphical or table forms, accessed via internet or mobile devices and is supporting presentation on public display units. The system is consisting from station level equipment and from a central station. The station level equipment is a DLX1 data logger comunicating to the analyzers, monitors and sensors. The entral station is a PC server with a software based on a Promotic Amb system. ECM AIR main functions Periodic data aquisition from the data loggers Presentation of collected data in form of wind roses, time lines, maps, tables or other desired formats Archiving of data in a safe data base

7 Processing Aquisition, Processing and Storage of Following Main Data Blocks from Station Dataloggers 1 hour and 10 minute averages of measured parameters (alternatively different time base can be defined) Calibration protocols including remote calibration control Station configuration including remote modifications Test functions Processing of alarms Monitoring of internal parameters of monitoring equipment Running of a database Data recovery upon communication or power problems Communication to public display devices Internet functions Data evaluation Pollution characteristics including statistics Exceeding of limit values Wind roses, time lines, graphs Protocols in accordance to EU regulations Logging of events and alarms

8 Monitoring functions Possibility to set all parameters in central PC Data presentation in tabular and graphical form Included Web Server possibility to present the monitoring on Intranet Web client visualization Multilingual support Safe password protection system Service functions Possibility of a remote service supervision Remote Access to the application allows flexible service on the main PC and data loggers both ECM AIR - Optimal function System extension Data export in different forms Support of new web clients Dispersion modelling to forecast pollution in desired locations defined in a GIS system Support of simpler monitoring devices using professional stations as a reference
