Product Service

YSI multiparameter long-term monitoring sondes and SonTek/YSI velocity instruments characterize water quality before, during, and after events such as storms, droughts, and floods, providing managers with critical data about the health of a water network.

In addition to event monitoring, establishing baseline water quality standards has become increasingly important for protecting source water as it is affected by urbanization and agricultural changes.

    600DW

    Sidestream measurements for distribution systems

     

    The YSI 600DW is a portable instrument which measures free chlorine and other parameters. Take readings at multiple points along a drinking water distribution system; the collected data gives you a comprehensive view of your water quality and can help you detect events of concern.

     

    YSI 6500 Process Monitor
     

    6500 Process Monitor

    Improve Operational Efficiency with Continuous Data

     

    With 8 scalable 4-20 mA current loop channels, 4 SPDT relays, and the ability to continuously monitor dissolved oxygen, conductivity, temperature, and pH via a YSI 6-Series sonde, the YSI 6500 helps you stay one step ahead in data collection.

     

    AQUARIUS Profiling Software Vertical Data Graph
     

    AQUARIUS Profiling

    AQUARIUS Profiling is designed for scientists and engineers who need to visualize and analyze vertical water column data in a powerful and flexible environment. Vertical water quality profiling data taken either manually or automatically and analyzed in AQUARIUS Profiling provides significantly more information than data collected at a single depth.

     

    YSI Pro2030 Field Dissolved Oxygen/Conductivity Meter
     

    Pro2030

    Field Dissolved Oxygen / Conductivity

    "YSI did a great job on this design.  Our staff of about 20 people consists of old veterans to recent college grads, and not one so far has had a negative comment."

    The Pro2030 provides everything you need in a handheld dissolved oxygen meter that automatically compensates for changes in salinity values. Rugged, simple and reliable.

    Measure DO, salinity, conductivity, specific conductance, TDS, barometric pressure and temperature.

     

    YSI EcoSense 9300 Photometer
     

    9300 / 9500 Photometer

    Waterproof, rugged, easy to use photometers

     

    The YSI 9300 and YSI 9500 are economical photometers in small packages for any application. These portable photometers allow you to easily take readings directly in the field for 100+ parameters.
