The Triton TR6 Turbidity Sensor measures turbidity or suspended solids in four selectable dual ranges featuring preset low and high ranges from 0 to 4000 NTU. It provides turbidity measurement in milligrams per liter, parts per million and percent solids to volume depending on the size, shape and composition. The sensor can be combined with the two-channel C22 Analyzer to monitor pH, ORP, DO, conductivity, pIon and more.
