1. Envi-Tech Scientific Technical Development and Environmental Ltd., Hungary June 2006, Budapest

2. History • Envi-Tech Scientific Technical Development and Environmental Ltd. is a spin-off company of the Research Institute for Solid State Physics and Optics of the Hungarian Academy of Sciences, was founded in 2005 • Envi-Tech develops, manufactures and markets laser technology-based, exclusive environmental equipment

3. Motivation • development and construction of a versatile, accurate and efficient equipment park for air and liquid pollution monitoring • to avoid, prevent and reduce harmful effects on human health and the environment • in compliance with the directives of the European Commission

4. Relevant EC directives • improve the air quality and avoid or reduce harmful effects on human health and environment (96/62/EC) • limit values of sulphur dioxide, nitrogen dioxide and other oxides of nitrogen, particulate matter and lead in ambient air (1999/30/EC) • limit values of benzine and carbon monoxide in ambient air (2000/69/EC) • control ozone content of ambient air (2002/3/EC)

5. Products • Airborne particle counters • Liquidborne particle counters • Mobile Environmental Test Lab Based on the long research experience of the RISSPO

6. Application fields • Stand-alone equipment for… • Mobile environmental measuring

7. Airborne Particle Counter APC-01-02/APC-03-02A • State of the art laser technology (no radioactive parts) • High resolution • Portable, stand-alone and installable • Total concentration, size distribution and particle concentration within size range measurements • Low maintenance

8. Airborne Particle Counter (APC-01-02/APC-03-02A) Our airborne particle counters are designed to measure thequality of ambient air indoor and outdoor. The applied state-of-the-art laser technology ensures high resolution, accuracy and life time, which couples with low maintenance requirements. Ourmobile, stand-alone or installabledevices can be used in environmental monitoring, indoor dust and clean room monitoring in industrial, pharmacological and health related applications. • Application fields • Ambient air quality monitoring • Indoor dust monitoring • Clean room monitoring

9. Liquidborne Particle Counter LQB-1-200 • State-of-the-art laser technology • High resolution • Portable and installable • Total concentration, size distribution, particle concentration within size range measurements • Shape factor analysis • Low maintenance

10. Liquidborne Particle Counter (LQB-1-200) Ourliquid-borne particle counter is designed to measure the size distribution, shape factor and concentration of particles suspended in various liquids with viscosity between 0.01 and 10 poise. The device can be used to testthe purity of parent solutions in pharmacology, haematology, biology, toxicology, health care, semiconductor process liquids, hydraulic fluids, environmental control, photochemical industry, refining industry, controlof screening and cleaning efficiency. • Application fields • Liquid quality monitoring • Cleaning efficiency screening

11. State of the art environmental monitoring technology • Complex air and moisture analysis • Available any time almost anywhere Mobile Environmental Test Lab The unique capability of measuring particles in air and moisture in virtually any place any time make theMobile Environmental Test Lab a powerful,efficient, cost effective tool in the field of environmental protection that can be effectively used to avoid, prevent or reduceharmfuleffects on human health and environment

15. Advantages of laser technology in contrast to: Gravimetric method b-ray method • higher accuracy • low maintenance • higher accuracy • no complicated authorizing process • no radioactive parts • low maintenance
