"ATIs Model Q45D-ODO Optical Dissolved Oxygen monitor utilizes a fluorescence-based sensor to provide a reliable oxygen measurement. This sensor will provide years of service and, unlike other optical sensors, will not be degraded by exposure to direct sunlight.","The optical dissolved oxygen sensor contains a fluorophore element that absorbs liqht at one wavelength, and then radiates light at a different wavelength (fluorescence). Oxygen molecules collide with the fluorophor which causes a non-radiative reaction, meaning the fluorophore element gives off less light. In short, molecular oxygen reduces (quenches) fluorescence and the concentration of dissolved oxygen can be determined by this quenching process.","All dissolved oxygen sensors are affected by process coating. Any material that slows the diffusion of oxygen into the reaction cell will cause an error in the oxygen reading. If the system doesn’t have a means to clean itself, the sensor will require frequent manual cleanings, which means higher maintenance costs. Our self contained Auto-Clean system generates a series of high pressure air blasts to remove foulants from the face of the sensor. Each cleaning cycle lasts approximately 3 minutes, during which the monitor outputs are placed in a HOLD condition to prevent false readings or alarms. The user can vary the cleaning cycle frequency from as often as once every two hours, to as little as once a day. ATI was the first to introduce a dissolved oxygen system that cleans itself with air. Others have tried to copy our system, but none are more effective at removing biological growth and other contaminants than the ATI Auto-Clean system. So don’t be fooled by imitation air pump cleaners that are minimally effective at cleaning your sensor. Trust the original Air-Blast system. Trust the best."
