The Model IN-2000-L2-LC-W1 uses UV absorption to continuously measure dissolved ozone concentrations in the liquid phase. It uses the stripping column method with advanced electronics design, to deliver highly accurate and stable readings of dissolved ozone. The model IN-2000-L2-LC-W1 is typically used in measuring dissolved ozone in drinking water, wastewater and DI water applications in a wide range of industries.
