ProOBOD Optical BOD Probe


The ProOBOD is designed for use with the YSI ProODO and ProDSS instruments. Optical, luminescent technology eliminates the probe warm-up period and membrane changes. The self-stirring BOD probe has a super quiet lab stirrer that helps ensure a representative sample and improves DO response times.

  • Smart sensor retains calibration in the probe
  • User-replaceable, low-maintenance sensor with +1-year life
  • 2-year warranty; reliable and serviceable, design reduces cost-of-ownership and reduces down-time
  • Guarded sensor - the sensor guard provides protection of the sensor tip when taking the BOD probe in and out of BOD bottles
  • Probe body tapered to fit into a standard 300 mL BOD bottle and international versions
  • Extremely quiet operation
  • No warm-up time required
  • Self-stirring to provide representative sample and increase response times
