Analytical Technology's Q45D Dissolved Oxygen Monitor - 2

ATIs Model Q45D Dissolved Oxygen monitor is designed toprovide reliable oxygen measurement and reduce 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 at the working electrode. This reaction produces a small current which is proportional to oxygen concentration.In applications where process constituents adhere to themembrane, frequent membrane cleaning is required. To keep the dissolved oxygen...

Analytical Technology's Q45D Dissolved Oxygen Monitor - 3

Clean Running Means Better Performance > Its a fact: A clean D.O. sensor performs better.ThatҒs because when theres nothing between the sensingmembrane and the water in the tank, you get uniform oxygen transfer for accurate measurement of dissolved oxygen content. And that translates into improved process performance, energy savings, and more effective water treatment.Trouble is, not all D.O. monitors are easy to clean. Units thatdonҒt clean themselves need to be removed for frequent maintenance. And those that do clean themselves with grindstones or brushes can be expensive and difficult...

Analytical Technology's Q45D Dissolved Oxygen Monitor - 5

Rebuildable CartridgeDesign > The sensor is constructed with a Teflon membrane that is used toisolate the electrochemical cell from the process. Oxygen that is dissolved in the process diffuses through the membrane and is reduced on the surface of the working electrode. The standard sensor uses a membrane with a 5 mil thickness to resist abrasion and tears in high solids applications. For processes that run at lower oxygen concentrations, or require a faster response time, a 2 mil membrane is optional.The electrochemical components of the sensor arecontained in an easily removable...
