 ATIs Model Q45D Dissolved Oxygen monitor provides reliable oxygen measurement and reduced maintenance costs. The galvanic dissolved oxygen sensor uses a rugged 5 mil Teflon membrane to resist mechanical abrasions and tears. The membrane serves as a barrier to allow molecular oxygen to diffuse into the reaction cell where it is reduced, producing a small current which is proportional to oxygen concentration.

In applications where process constituents adhere to the membrane, frequent membrane cleaning is required. To keep the dissolved oxygen system nearly maintenance free, an optional Auto-Cleaner can be included to remove those materials that build up on the sensor membrane. The cleaning cycle is user selectable to maximize the cleaning effectiveness. When sensor maintenance is required, our cartridge-based sensor makes it fast and easy. Where other manufacturers make you throw away the cartridge, we’ve made our cartridge field repairable. We also include enough replacement parts to rebuild your cartridge ten times.
 
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.
