| • Maximum depth rating for optical probes is 200 feet, 61 m. Turbidity and Rhodamine are available in a Deep Depth option (0 to 200 m). Anti-fouling optical probes have depth rating of 200 m. •• Rapid Pulse is only available on 6920 V2-1 (one optical port version). ••• Report outputs of specific conductance (conductivity corrected to 25° C), resistivity, and total dissolved solids are also provided. These values are automatically calculated from conductivity according to algorithms found in Standard Methods for the Examination of Water and Wastewater (ed 1989). •••• Freshwater only. Maximum depth rating of 50 feet, 15.2 m. 6600 V2-2 has 3 ISE ports; not available on the 6600V2-4. |
