HI7660-28 Low Range Turbidity Probe The HI7660-28 are nephelometric turbidity probes designed for use with Hanna Instruments® HI510 or HI520 Universal Process Controller. The system is designed to measure low turbidity values according to the nephelometric method (ISO 7027 – EN 27027). An integral temperature sensor measures water temperature and adjusts the probe signal for temperature-related changes over the range of 0 to 50 °C (32 to 122 °F). The controller displays both measurements simultaneously. The system is suitable for applications in drinking water, municipal and industrial water treatment, desalination and water quality monitoring. The majority of low-measurement applications using the HI7660-28 probe require installation in a pressurized ¬ow cell. The HI7676602 ¬ow cell is designed to eliminate ambient light eects and maintain sample pressure inside the ¬ow cell. This minimizes sample out-gassing, a common problem in many turbidity systems that can cause measurement errors.
