Dissolved Oxygen Monitor | Water Quality Monitor

ATI DISSOLVED OXYGEN SENSOR TYPES OPTICAL SENSOR The optical DO sensor operates on a light-based principle called “fluorescence” which is a type of luminescence. Certain chemical compounds will absorb one type of light energy, and then emit a different type of light energy. This light emission is called luminescence. The active portion of the sensor has a metal-based compound embedded in a ...

AquaMetrix Optical O2 Luminescent DO Sensor (ODO2 ...

This is the only optical dissolved oxygen sensor that outputs directly 4-20 mA for the %-saturation and concentration (mg/l or ppm). It can connect to a PLC or the Aqua-Metrix AM-2300 controller. Optical DO sensors offer advantages over electrochemical DO sensors in that they are inherently self referencing, require no warm-up period. These sensors do not require constant flow to maintain a ...

Dissolved Oxygen Meter with Optical Sensor Technology ...

Dissolved oxygen measurement technology has advanced from electrochemical sensors, such as polarographic and galvanic, to luminescent-based, optical sensors. YSI optical DO sensors are non-consumptive, meaning oxygen is not consumed during the measurement. As a result, there is no flow dependence or stirring required with ODO, allowing for the most accurate readings in the field.
