Additional decisive classification information
Monitoring is utilized in many different industries and in surface waters to continuously dissolve oxygen . In recent years the optical approach has become much more popular. This makes it desirable to restructure the hierarchy in decisive classification as follows:
Formerly optical -- polarograhic , galvanic – other
New optical – electrochemical
Electrochemical children are
· polarographic
· galvanic
Optical have some advantages when needing to measure in ppb such as in brewereies, power and semiconductor plants.
Note that this analysis deals with continuous in line instruments as opposed to hand held.
Further analysis will further determine this structure . For example is huminescent and child of poloarographic. Should we have “other electrochemical as a child equal to polarographic and galavanic or should himinescent be a sibling of polarographic

Title: YSI Optical Sensing Technology Superior to Rapid Pulse Polarographic DO Sensors for Long-Term Monitoring |
Information and case study on the YSI ROX™ luminescent dissolved oxygen sensor, which differs from polarographic-style DO sensors. The durability of the sensing element and the stability of the signal have been improved significantly in the ROX sensor. YSI says that with the ROX sensor, maintenance intervals stretch from two weeks to six weeks or longer in heavy fouling environments.
