Dissolved Iron Analyser

precision submersible chemical sensor

Based on advanced lab-on-chip technology, this system performs high-quality dissolved iron measurements using the colourimetric ferrozine method. It can be programmed to measure both Iron II and Iron III (via onboard acidification and reduction processes). The system is robust and fully submersible to 6000 m deep. Key applications include scientific (e.g. iron cycling in rivers, coastal and hydrothermal areas) and industrial (e.g. corrosion and process monitoring).
