PASPORT Optical Dissolved Oxygen Sensor - PS-2196



Makes it easier than ever before to measure dissolved oxygen in the field or in a lab environment. The luminescent technology has several advantages over a galvanic dissolved oxygen sensor including:

  • There is no warm-up time
  • No calibration is required
  • It is low maintenance - no filling solution or electrode polishing
  • There is a built-in temperature and pressure compensation
  • No flow dependency
  • Optional Salinity Compensation

Perform these labs with the Optical Dissolved Oxygen Sensor

  • Photosynthesis, Respiration and Fermentation labs
  • Monitoring Water Quality
  • Measuring Net Primary Productivity
  • Modeling Ecosystems
