The 6600 V2-4 also measures these parameters: dissolved oxygen, turbidity, chlorophyll, and blue-green algae; the V2-2 measures two of the four parameters simultaneously. Additional calculated parameters include total dissolved solids, resistivity, and specific conductance.

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 for real-time turbidity monitoring, dissolved oxygen monitoring, algae monitoring, and more.

In addition to turbidity, chlorophyll, and rhodamine, YSI offers these optical sensors:

ROX Reliable Optical Dissolved Oxygen

The ROX sensor uses lifetime luminescence detection technology to offer the most reliable oxygen sensor with the lowest possible maintenance effort. The sensor is insensitive to hydrogen sulfide interference and does not require regular membrane changes.

Blue-Green Algae (BGA)

YSI’s fluorescence-based blue-green algae sensors will allow you to monitor blue-green algae populations where their presence is a concern. Whether providing an early warning to an algal bloom, tracking taste and odor-causing species in drinking water supplies, or conducting ecosystem research, YSI BGA sensors will provide sensitive and reliable in situ data.

Sensor performance verified*

The 6600 V2 sonde uses sensor technology that was verified through the US EPA’s Environmental Technology Verification Program (ETV).
