YSI ODO technology reduces the time required calibrating and maintaining sensors while utilizing a user replaceable sensing element that requires approximately an annual replacement. There are no electrodes to clean or solutions to change. Based on usage, calibrations can be stable for up to one year and are stored in each sensor. Optical technology also increases DO accuracy and eliminates probe fouling by common gases such as hydrogen sulfide.

  • Expanded DO range of 0-500%
  • Non-consumptive luminescent method eliminates the need for stirring
  • Easy to read graphic, backlit display and keypad for use in any lighting condition
  • Truly field-worthy, impact resistant, IP-67 waterproof case and connectors; rubber over molded, non-slip case, for extra durability and grip
  • User-replaceable cables in lengths of 1 to 100-meters; cable management kit included with 4-meter and longer cables
  • USB connection allows interaction with powerful desktop Data Manager software
  • 3-year instrument warranty; 2-year cable and probe warranty
  • Stores 2000 data sets (sensor data, date, time, site and user defined information)
