D-OPTO – Optical DO (Dissolved Oxygen) Sensors

The D-Opto range of dissolved oxygen instruments. D-Opto Sensor “The optical sensor on the probe is more reliable than membrane based probes that we’ve used in the past and require less frequent calibration.” – Dr Roger Young (Cawthron Institute New Zealand), following a survey of the health of 11 large rivers across New Zealand. More… D-Opto Logger. Most studies of this type only ...

Optical Vs. Electrochemical Dissolved Oxygen Sensors ...

Optical Vs. Electrochemical Dissolved Oxygen Sensors. For most algae applications, DO is a key parameter: high DO is a sign of growth, but too much DO inhibits growth. Generally the oxygen is measured dissolved in the liquid, but in some applications head space O2 is also useful. There are two forms of DO sensor: electrochemical, and optical.

Optical Dissolved Oxygen Sensor, Hamilton VisiFerm ...

Dissolved oxygen is required for the survival and growth of many aquatic organisms, including fish. The concentration of dissolved oxygen may also be associated with corrosive and photosynthetic activity. The absence of oxygen may permit anaerobic decay of organic matter and the production of toxic and undesirable esthetic materials in the water. Main applications for this sensor are ...

Optical O2 Sensors - Optical Sensor Technology

Our oxygen sensors cover a measurement range from 1 ppb up to 45 ppm dissolved oxygen, and even measure ultra-low oxygen traces down to ppmv O 2 in gases. Compared to other methods, optical O 2 sensors do not consume the analyte during measurements, which is an important advantage when measuring in low oxygen environments. All of our oxygen sensors come pre-calibrated, and …

The Pros and Cons of Optical Dissolved Oxygen Sensors ...

· Optical and electrochemical dissolved oxygen sensors can both be highly accurate, especially right after you’ve calibrated them. But optical sensors experience less drift than electrochemical ones (also called Clark cells). Drift means that, over time, dissolved oxygen sensors can become less accurate until they are calibrated again. The United States Geological Survey put it …
