- AOOS9000 Polarographic Online Oxygen Content Analyzer
◆Measurement principleThe product utilizes a polarographic-type electrode with an applied polarization voltage of 0.6–0.8V, typically consisting of a cathode made from precious metals such as platinum or gold, and an anode made from silver. When a certain polarographic (polarization) voltage is applied between the cathode and anode, oxygen molecules from the gas permeate through the oxygen-permeable membrane and are reduced at the cathode, generating a diffusion current proportional to the oxygen concentration. The main unit then calculates the oxygen content based on this current.
◆Main characteristics
▶The instrument adopts a panel-mounted (160×80) structure;▶4-window high-brightness LED display;▶Conventional digital display meter operation menu;▶Optional pre-installed simplified pretreatment device;▶Domestic sensors;▶Sensor directly leads out with cable;▶Simultaneously display parameters such as measuredvalues and alarm values;▶The panel-mounted snap-in structure facilitates easyinstallation.◆Application ScenariosThe product is suitable for measuring oxygen content and providing over-limit alarms in large and medium-sized hyperbaric oxygen chambers in hospitals. It also applies toindustrial and mining enterprises, ship cabins, tunnels, coal mines, chemical equipment containers, gas; internal combustion engine exhaust, thermoelectric devices, smelting,boilers, kilns, environmental protection monitoring, oxygen generators, quality inspection,electrolytic hydrogen equipment, submarines, artificial satellites, civil air defense,aerospace; controlled atmosphere storage of grains, tobacco leaves, fruits, and vegetables, medical ventilators, anesthesia machines, and various other scenarios requiring oxygencontent measurement. Additionally, it can be used for oxygen level control in respiration experiments involving crops and animals. -
