The 6600V2 sonde is a water quality monitoring package available with simultaneous measurement of conductivity (salinity), temperature, depth or level, pH/ORP. With models V2-2 and V2-4, two or four additional optical sensor selections measure parameters of dissolved oxygen, turbidity, chlorophyll, and blue-green algae. Additional calculated parameters include total dissolved solids, resistivity, and specific conductance.
