AOOS9000 Polarographic Online Oxygen Content Analyzer

Oxygen content analyzers are currently used online in industrial production automatic control.Analytical InstrumentPrimarily used for analyzing oxygen content in mixed gases and molten steel, as well as for continuous monitoring of oxygen levels in the synthesis ammonia process in fertilizer factories. It can also be paired with electrostatic deasphalting equipment to promptly cut off the static high voltage when oxygen levels in the chemical process exceed the set value, preventing accidents. The instrument is also suitable for industrial and mining enterprises, ship holds, tunnels, coal mines, chemical equipment containers, water purification, coal gas, internal combustion engine exhaust, thermal electric equipment, smelting, boilers, kilns, environmental protection monitoring, oxygen generators, quality inspection, electrolytic hydrogen equipment, civil defense, aerospace. It is also used for grain, tobacco leaves, fruit, vegetable controlled atmosphere storage, medical department ventilators, and can be used for oxygen control in crop and animal respiratory experiments.
