The H78673 oxygen control unit is an advanced version of the KY series oxygen control system. It incorporates the latest production technology and engineering expertise, ensuring high performance and reliability. The instrument features a high-quality oxygen electrode membrane imported from abroad, which ensures accurate and stable oxygen detection. Its circuit design uses state-of-the-art large- and medium-scale integrated circuits, combined with a 3-digit, high-brightness LED display for clear and easy reading.
This device offers multiple control functions, including digital preset settings for upper and lower limit thresholds, along with audible and visual alarms to alert users when oxygen levels exceed safe ranges. It also provides electric shock output control and automatic zero stabilization, ensuring that the oxygen concentration in the controlled system remains within a specified range.
The H78673 is primarily used for oxygen content monitoring and over-limit alarm in large and medium-sized hyperbaric oxygen chambers in hospitals. According to guidelines from the Chinese Society of Hyperbaric Oxygen Medicine, oxygen levels in these chambers should be maintained at 25% in certain conditions, with general safety limits below 30%. Beyond medical applications, it is also widely used in industrial and mining environments, such as in cabins, tunnels, coal mines, chemical containers, internal combustion engine exhaust systems, thermal power plants, smelting operations, boilers, furnaces, and environmental monitoring.
Additionally, it is suitable for oxygen content measurement in nitrogen generators, oxygen enrichment machines, injection quality checks, electrolytic hydrogen equipment, submarines, satellites, civil defense systems, aerospace applications, and modified atmosphere storage for grains, tobacco, fruits, and vegetables. It also supports oxygen control in breath experiments involving crops and animals, making it a versatile and essential tool across multiple industries and research fields.
