VisiWater Optical Dissolved Oxygen sensors

VisiWater sensors are optical technology sensors intended for the measurement of dissolved oxygen submersible applications in the environmental water industry due to the long fixed cable (10m) and IP68 rating. They require less maintenance due to their integrated self-diagnostic opto-electronics, and absence of a mechanically sensitive membrane or corrosive electrolyte.  Optical DO technology ensures no CO₂ fouling, fast response time and stable measurement.

Accurate measurement in environmental applications.

Hamilton's VisiWater optical dissolved oxygen sensors are built for accurate and reliable measurement of dissolved oxygen in environmental monitoring. Designed with optical DO technology, these sensors eliminate common issues associated with traditional amperometric designs, such as CO₂ fouling and membrane sensitivity. The sensor's IP68-rated enclosure allows full submersion, while its 10-meter fixed cable ensures versatile deployment in aquatic environments. Integrated opto-electronics provide real-time diagnostics and measurement stability, requiring significantly less maintenance and enhancing long-term performance. They are ideal for applications in water quality monitoring, wastewater treatment, and environmental studies.

FAQ

Does salinity impact my DO measurement?

Yes, salinity of a solution generally has an inverse relationship to the dissolved oxygen content within the solution. Arc sensors can have the salinity value of the liquid added in to correct the measurement by using ArcAir.

FAQ

Does temperature impact my oxygen measurement?

Yes, in a closed system, gas phase temperature is directly proportional to pressure and therefore measured oxygen content. In solution, temperature is inversely proportional to dissolved oxygen content.

FAQ

When should I calibrate my DO sensor?

The frequency of calibration will depend upon the duration of process runs and the accuracy required for process control. In bioreactor applications calibration can be performed before sterilization; however many customers choose to calibrate after sterilization as well.
