The main reasons why an Optical DO sensor is a better choice for measuring dissolved oxygen
- Stability, sensitivity, speed of response, accuracy in low DO conditions and minimal maintenance requirements.
- Oxygen is not consumed as part of an electrochemical reaction and optical sensors do not require sample flow or stirring for accurate readings.
- Results demonstrated excellent correlation between the optical sensor and the Winkler titration method.
- Optical sensors respond faster than membrane-based sensors to changing temperature and DO
- Readings are stable and drift is minimal over long-term deployments.
- Durable sensing element offers a longer operational life than an oxygen-permeable membrane.
- Maintenance and calibration requirements are drastically reduced, minimizing site visits and operational costs.
- Material costs are reduced. Clark-cell sensors require frequent replacement of membranes and filling solution. The optical sensor Cap is replaced annually.
