2BTech-106W Ozone

2BTech-106W Ozone - Ozonation of Water

The Model UV-106-W Aqueous Ozone Monitor™ uses our patent-pending MicroSparge™ technology to measure dissolved ozone in water with high precision and accuracy.  Unlike most dissolved ozone sensors, the instrument does not make use of a membrane that will foul over time.  Instead, dissolved ozone is measured by nearly complete sparging of ~2 mL of water with ozone-scrubbed ambient air and integrating the gas-phase concentration of ozone stripped from solution.  A small correction, based on the temporal profile of ozone removed from solution, is made to account for any ozone remaining in solution.  Because ozone is measured in the gas phase, interferences from particles and dissolved inorganic and organic compounds are removed, making the instrument applicable to both ultra pure water and “dirty” water, such as drinking water, which can contain a wide variety of dissolved inorganic and organic impurities and suspended particles.
