YSI - Model 6-Series -Multiparameter Sondes

Utilize YSI’s new optical sensor design and anti-fouling wiper control for improved reliability during extended deployments.

• Self-cleaning optical sensors with integrated wipers remove biofouling and maintain high data accuracy
• Field-replaceable sensors make trips to the field quick
• Optimal power management and built-in battery compartment extends in situ monitoring periods

Maximum depth rating for all optical probes is 200 feet, 61 m. Turbidity and Rhodamine are also available in a Deep Depth option (0 to 200 m).
Rapid Pulse is only available on 6600 V2-2 (two optical ports 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.
**In YSI AMCO-AEPA Polymer Standards.

Maximum depth rating for all optical probes is 200 feet, 61 m. Also available in a Deep Depth option (0 to 200 m).
