“ATI’s Model Q45D Dissolved Oxygen monitor is designed to provide 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.”
