The H78673 oxygen control unit is an advanced version of the KY series oxygen control system. It incorporates the most cutting-edge production technology and engineering expertise available today. The oxygen electrode membrane used in this instrument is imported, ensuring high accuracy and long-term stability. The internal circuitry is built using state-of-the-art large- and medium-scale integrated circuits, combined with a high-brightness 3-digit LED display for clear and easy reading.
This device features a digital dial preset function for both upper and lower limit settings, along with audible and visual alarm systems to alert users when oxygen levels go beyond the set range. It also includes automatic zero stabilization and electric shock output control, allowing the oxygen content within the controlled system to remain within a specified range.
The H78673 is primarily designed for oxygen content measurement 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, the oxygen concentration should be maintained at 25% in certain areas, and generally not exceed 30%. Beyond medical applications, it is also widely used in industrial and mining environments, as well as in enclosed spaces such as cabins, tunnels, coal mines, chemical containers, and internal combustion engine exhaust systems.
Additionally, it is suitable for use in thermal power plants, smelting facilities, boilers, furnaces, environmental monitoring systems, nitrogen generators, oxygen enrichment machines, injection quality testing, electrolytic hydrogen equipment, submarines, satellites, civil defense systems, aerospace applications, and modified atmosphere storage for grains, tobacco, fruits, and vegetables. It is also used in medical ventilators, anesthesia machines, and for breath experiments involving crops and animals. This versatile instrument ensures precise oxygen control in a wide range of critical and demanding applications.
