Galvanic DO sensor versus optical DO sensors
May 17, 2010
ATI manufactures both galvanic and optical-style dissolved oxygen monitors. The optical type is a recent addition to ATI's lineup; ATI has been manufacturing reliable galvanic-style monitors for years. Thus, they're in a strong position to examine the two types of monitors side-by-side without bias. After ten months of side-by-side testing, they've found that the two monitors perform almost exactly alike
. The result itself isn't especially surprising to the factory, though it may come as a surprise to customers who have been "sold" on the notion of improved efficacy from optical sensors. More important than the means of measurement appears to be the effectiveness of the cleaning system used to keep the sensor working, and ATI's unique air-blast Auto Clean system is exceptionally reliable -- and virtually maintenance-free.
