Section 3: Applicability Range

This gauge is suitable for measuring oxygen content and exceeding-alarm in large and medium-sized hyperbaric chambers in hospitals (note: according to the requirements of the Chinese Medical Association Hyperbaric Oxygen Society, oxygen content in hyperbaric chambers should be controlled below 25% where conditions permit, generally below 30%); it is used for continuous monitoring of oxygen content in gas during the synthesis ammonia process in fertilizer factories, and can be matched with electrostatic deasphalting equipment. It can promptly cut off the static high voltage when the oxygen content in the chemical process exceeds the set value, preventing accidents. The instrument is also applicable to industrial and mining enterprises, ship compartments, tunnels, coal mines, chemical equipment containers, water purification plants, gas, internal combustion engine exhaust, thermal electric equipment, smelting, boilers, kilns, environmental protection monitoring, oxygen generators, quality inspection, electrolytic hydrogen equipment, submarines, artificial satellites, civil defense, space travel. It is used for oxygen content measurement in grain, tobacco leaves, fruits, vegetables, and medical department ventilators, anesthesia machines, and various other situations. It can also be used for oxygen quantity control in crop and animal respiration experiments.
