1 GRIMM Aerosol Technik Grimm Instrumentation The future of particle measurement Ing. Wolfgang Brunnhuber Environmental Division Manager

2 ENVIRONMENTAL Product Groups Ambient air monitoring, outdoor solutions EN12341 & EN14907 PM10, PM2.5, PM1 & TC simultaneously in real time - 0,25µm up to 32µm

3 AGENDA Company Information General features PM10 EN12341 PM2.5 EN14907 Customer Benefits

4 General features 31 channel size distribution Different measurements simultaneously No probe heating only dehumidifiaction No loss of Semi-Volatile compounds Chemical specification possible Gas analyses possible

5 Measured values Possible measurements all simultaneously real time: PM10, PM2.5 & PM1 or TSP, PM2.5 & PM1 or PMcorse, PM10 & PM2.5 or PM10, PM2.5, PM1 & total counts (in network mode or online) Counts in 31 size channels

6 General features Results are : in real time fast mode 6 seconds not location specific no seasonal mass corrections no radioactive source no sensitivity to vibrations. With RS-232 and enviro-protocoll Data is reproduable Instruments can be exactly calibrated

7 ENVIRONMENTAL DATA IN REAL TIME

8 Particle PM-10 and Concentration PM-2.5 values in 15 at (or the 31) same Channels time with continuous one unit

9 General features Particle counts: 1 > p/l Measurement period: 6sec upwards Dust mass 0.1 > 1500µg/m³ Reproducibility 3% max range Alarm level: 0.01 > 100mg/m³ Auto star mode: after power failure Self test: after each start Automatic flow control sample flow rate 72l/h Power supply possibilities: 230VAC, 50Hz Each instrument has an included information storage and can be upgraded with a PCMCIA data storage card. All models have a RS 232 interface and so the possibility of wireless and remote date connection. The connection to the device is over hyperterminal possible. The RS232 interface has no handshake protocol and a ASCII code transmission.

11 EDM180 stationary ambient monitor * Certified for PM10 according to EN12341 * 19zoll rack mount * Special NAFION dehumidification system * GESYTEC MODE for networks * Long time measurement * Very low TCO s

12 EN12341 PM10 * Official publicated certification on the 8th of April 2006 by the German UMEG

13 PM10 Germany 106 days Winter time comparison between Grimm and grafimatrical reference system Leckl filter collector Correlation 0,974 and data quality 95%

16 EN14907 PM2.5 The systems are just under certification process letter from the 23rd of may 2008:

17 PM2.5 Netherland Raw data without any correction 30days, correlation to reference R² = 0,95, data quality 100%

18 PM2.5 Austria Raw data without any correction 34days, correlation to reference R² = 0,93, data quality 98%

19 PM2.5 Germany 116 days Corrected data 116days, correlation to reference R² = 0,95, data quality 100%

20 PM2.5 Germany 116 days

23 Customer benefits Maintenance The system is designed in such a way that only a minimum of maintenance is needed. Every 6 months a system check with a easy to use test kit. Calibration control every Reduction of life time costs Automatically Check System A complete automatically self test and control system is watching over the instruments quality and reports errors

24 Customer benefits Consumables No Consumables are needed (for example filter band) Reduction of costs (at other instruments this costs are up to within 3 years) Energy costs are lower The maximum power consum is 50W/h Reduction of energy costs (example of Helsinki: 3 EDM W, for the same number of values PM10 & PM2.5 6 TEOM 3000W. Cost save in Helsinki within 10 years )

25 Customer benefits Simultaneous three PM values The only available fine dust monitor, EN approved for PM- 10 witch the ability to measure simultaneously PM-10 and PM-2.5 and PM-1 in µg/m3 Count Values Additional information of the total fine dust particle concentration will allow the understanding of the aerosol source measured. Data are in Particles / litre. Risk Management Fast data presentation, combined with the meteorological sensors will allow to identify the source direction and the possible risk associated. Distribution models can be feed with such information s.

26 Differences to the competitors (TEOM, SHARP, BAM,...) 4 different values simultaneously in real time No heating of the probe therefor no loss of SEMI Volutiles the only instrument that includes the SVC fraction in all PM values No radioactive source is in use No consumables (no change of filters, cardriges,...) No summer/winter correction No external pump systems (all in one 19 rack solution) No specification of the measurement range by the probe pipe head (TSP head is used) Easily change of measurement if regulation changes by firmware update no need of hardware change!

27 Where are our instruments in use? Generally the EDM180 is running in several states of Europe and the world in national networks and shows very good results in equivalency to the gravimetrical reference methods. Some of these countries are: Germany Belgium Austria Italy Spain Czech Republic China South Africa Netherland Mongolia Bosnia Croatia Switzerland Korea United Arabian Federation Emirates Australia Canada Serbia Turkey
