The Triton TR6 turbidity sensor is a nephelometric device for analysis of turbidity or suspended solids. Four selectable dual ranges are available with preset low and high ranges: 0 to 4000 NTU. Turbidity is measured in milligrams per liter, parts per million and percent solids to volume depending on the size, shape and suspended solids composition. The C22 analyzer combines turbidity with measurements for pH, ORP, pIon, conductivity or dissolved oxygen.
