An easy way to install YSI ODO™ technology at your site, tank, or pond.

  • Overview

    Engineered specifically for aquaculture applications, but at home in any Modbus system, the optical dissolved oxygen (ODO) sensor can be used to ensure adequate oxygen levels for your livestock or for improved energy efficiency. With YSI’s ODO RTU (Remote Terminal Unit), you’ll benefit from reduced costs, less maintenance, and better data.

    ODO RTU utilizes the most advanced DO technology and can be connected anywhere without the need for special connectors. Additional inputs for barometric pressure and salinity are used to accurately calculate the DO% and mg/L. ODO RTU is also available with built-in conductivity measurement to automatically compensate for salinity.

    • Key Benefits


      Smarter Sensors
      Industry-leading optical dissolved oxygen provides higher accuracy readings with less maintenance


      Seamless Integration
      Modbus communication integrates directly to the PLC or data logger you already have without additional software


      Automatic Compensation
      An optional built-in conductivity sensor automatically compensates for salinity - removing the guesswork


      Less Maintenance, Long Warranty
      2-year cable and probe warranty with user-replaceable DO cap


      Not for use with the ProSolo or ProODO handheld meters.
