YSI ProODO™
Optical Dissolved Oxygen Meter

The new ProODO™ provides traditional YSI quality in a handheld dissolved oxygen instrument with luminescent
optical dissolved oxygen (DO) technology. The ProODO utilizes “smart” digital sensor technology which stores calibration data within the sensor. This allows probes to be placed on any ProODO instrument without recalibration.

YSI ODO technology reduces the time required to calibrate and maintain 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.

• Expanded DO range of 0-500% with a response time of T90 in 15 seconds
• Non-consumptive luminescent method eliminates need for stirring
• Optical technology increases DO accuracy and eliminates probe fouling by common gases such as hydrogen sulfide
• Easy to read graphic, backlit display and keypad for use in any lighting condition
• Truly field-worthy, impact resistant, IP67 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
• Stores 2000 data sets (sensor data, date, time, site and user defined information)
• Multiple languages include English, Spanish, French, Italian, Norwegian, Portuguese and German. Asian language support in the future.
• 3-year instrument warranty; 2-year cable and
  probe warranty
