Testing Laboratory


Since 1996 we operate a testing laboratory equipped with laboratory and on site measuring instrumentation for water, biomass, bioenergetical, biotechnological, climate-environment-health protection processes, reaserch and monitoring parameters.
We operate in conformity of ISO EN 17025 rules. After analyses we elaborate engineering expert reports and operative technological instructions.
Head of laboratory : Ms. Marianna Percsics complex laboratory analysises, biotechnology and chemical technology developer.
