  • Overview

    The ProDSS is a portable water quality instrument used for sampling applications in a variety of environments, such as:

      • Surface Water
      • Wastewater
      • Coastal/Estuarine
      • Aquaculture
      • Groundwater 
      • Laboratory

    Equipped with smart sensor technology, the ProDSS automatically recognizes sensors while retaining their calibration data. Its 4-port cable assembly allows you to choose any four sensors at a given time.

    ProDSS Parameter Options:

    • Specific Conductance1
    • Salinity1
    • Total Dissolved Solids (TDS)1
    • Resistivity1
    • Seawater Density
    • Total Suspended Solids (TSS)
    • Depth

    2Included in Handheld

    Some sensors are EPA approved for drinking water and wastewater compliance reporting.

    Note: It is recommended that a Conductivity/Temperature Sensor (626902) is installed in every ProDSS 4-port cable assembly for accurate temperature compensation and measurement.

      • 3-year instrument warranty; 2-year cable warranty; sensor warranty varies by sensor

    Additional Cable Offerings

      1. Provides accurate DO measurements with an optical dissolved oxygen sensor and an inline conductivity sensor, allowing for real-time salinity compensation.

      2. ProODO Sensor and Cable Assembly

        An optical dissolved oxygen probe assembly with cable for a DO-only instrument. Alternatively, if searching for a DO-only handheld instrument, explore the ProSolo

      3. ProOBOD Optical BOD Probe

        EPA-approve method for wastewater compliance reporting of BOD and CBOD. Designed for use in the lab, featuring a self-stirring probe.

      All ProDSS instruments include a rechargeable lithium-ion battery (pre-installed), hand strap, USB cable for charging the ProDSS battery and for connection to a PC, universal AC charger, cable for connection to a USB memory stick, ProDSS quick start guide, and USB memory stick containing Kor Software and a digital copy of the user manual.

    3. Software
      Kor Software - v1.4.1.10
      Oct 2024

      Kor Software is designed to interface with both EXO and ProDIGITAL (DSS) instruments, including the new ProSwap Logger. Use Kor Software to view live data, import/export recorded data, calibrate sensors, manage handheld settings, set up deployments, and more! This software is included on a USB flash drive that ships with all new instruments, and the latest version can be found here on the website.

      Use with the following instruments:

      • EXO Sondes
      • ProSwap Loggers
      • ProSwap Handhelds
      • ProSolo Handhelds
      • ProDSS Handhelds

      Functions:

      • Calibrate Sensors
      • View and Record Live Data
      • Download and View Recorded Data
      • Set Up Deployments
      • Configure Handheld Settings
      • Adjust Instrument and Sensor Settings

      What's New:

      Kor Software replaces both KorEXO and KorDSS as the primary user interface for managing EXO and ProDIGITAL (ProSwap, ProSolo, and ProDSS) instruments and data.

      Note: Be sure to update instrument firmware before attempting to download data.
