The 2020 Series of turbidity meters assures long-term stability and minimizes stray light. The 2020we and 2020wi turbidity meters are designed to meet U.S. EPA and ISO standards, respectively. EPA specifies a tungsten lamp, while the ISO method specifies an LED. When samples with color are being analyzed, the 2020wi is recommended, as interferences are reduced. Visit the company at StormCon booth #510.
