Make the most of your environmental monitoring.

The YSI 6600 V2-4 data sonde is one of the most comprehensive water quality monitoring platforms available with simultaneous measurement of conductivity (salinity), temperature, depth or level, pH/ORP, and more.

Instrument only. Cables, probes/sensors, and accessories sold separately.

  • Overview

    The V2 sondes represent a proven generation of multi-parameter sondes from YSI. Perfect for harsh fouling environments, YSI's optical sensors feature an integrated wiper that prevents the impacts of biofouling, a corrosion-resistant titanium wiper shaft, and replaceable seals.

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

    Utilize YSI’s 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
    • 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.


    Features:

    • Internal battery pack & memory for long-term, unattended deployments
    • All sensors are field-replaceable, and optical sensors feature self-cleaning wipers
    • Compatible with real-time data logging systems
       

    The YSI 6600 V2-4 has the following available ports:

    • (1) Temperature/Conductivity
    • (1) pH or pH/ORP
    • (4) Optical (Dissolved Oxygen, Turbidity, Chlorophyll, Blue-Green Algae, and/or Rhodamine)
