Online Optical DO Analyser – OxySense
The OxySense DO analyser range of online Dissolved Oxygen Meters utilises the very latest and best optical sensor available in the world today. It is an optical luminescent device which is extremely resistant to abrasion, extremely stable, and has greatly reduced maintenance and whole life costs. Coupled with the automatic self cleaning and self verification, the OxySense online DO analyser is as close to ‘fit and forget’ as it gets.
The OxySense Online Optical Dissolved Oxygen Analyser with self-cleaning and self-verification offers enhanced reliability and unrivalled low maintenance. Optical DO meters have largely replaced electrochemical DO sensors (Clark Cells) due to their better reliability and lower maintenance requirements.
The OxySense DO sensor is available with different controllers giving you the same great performance with different communication, display, and control options.
The sensing element (lumiphore) is activated, or excited when illuminated with a blue light. When activated, the lumiphore then emits red light with an intensity that is inversely proportional to the amount of oxygen dissolved in the water.
There is also a time delay between the peak emission of blue light and peak response of fluoresced red light. The amount of delay is inversely proportional to the amount of oxygen present. This time delay can be expressed as a phase shift between the wave patterns of incident blue light and the fluoresced red light. This is in turn reported by the electronics as a ppm or mg/l reading of Dissolved Oxygen. The advantages of this technology are that it is more stable than traditional electrochemical devices and far more resistant to abrasion. By using the state of the art sensor and electronics together the reliability, accuracy, and flexibility of the OxySense Online Optical DO analyser is far superior to that of its competitors. great value for money.
The OxySense Online Optical DO Analysers are used in Aeration Lanes and Oxidation Ditches to control the air blowers. What is probably the world’s most reliable Dissolved Oxygen sensor from In-Situ® the RDO® sensor coupled with Pi’s award winning electronics provides up to 36 months between maintenance and calibration events and results in probably the best online DO analyser available in the world today.
The self-verification option is revolutionising calibration routines in that this Dissolved Oxygen analyser is able to check its own functionality on a regular basis and call for calibration when necessary.
