Environmental sciences are characterized by multidisciplinarity, covering many fields such as electrochemistry, physics or biology. Innovative concepts of scientists in this field are multidisciplinary, requiring the use of specialized and precise apparatus and systems from various fields, such as infrared sensors, corrosion sensors, systems for studying electrochemical phenomena, interfaces (gas-liquid, gas-solid, liquid-solid). PREVAC systems answer these requirements and at the same time can be successfully adapted to any, even the most innovative investigation work.
