Silica (silicon dioxide, SiO₂) levels are monitored in a wide variety of applications, such as aquaculture, industrial applications, heating systems and reverse osmosis (RO) plants. It is important to monitor the silica concentration in aquaculture to limit growth of diatoms, while silica levels in heating systems and reverse osmosis plants affect the efficiency of the processes.

Hanna offer a wide range of instruments for accurate measurement of silica levels, including Chemical Test Kits and Photometers.
