Portable Oxygen Concentration Content Tester Meter Detector

The instrument's sensor adopts advanced oxygen electrode manufacturing process technology, which achieves long life, high stability, high precision, fast response time, and can resist the interference of various harmful gases (especially the interference of hydrogen). The oxygen electrode produced by our factory has also obtained Chinese patents. The instrument host is assembled by an imported A/D conversion circuit and digital display, which has the characteristics of easy operation and wide range of 0.00%-100%, particularly suitable for the following occasions. The sensor of the instrument is an electrochemical polarographic diaphragm oxygen electrode. It uses a platinum cathode and a silver-silver chloride anode. Potassium chloride is used as an electrolyte, and the diaphragm material is a polyperfluoroethylene propylene film selected to transmit oxygen. The electrode reaction is as follows Cathode: O ₂ + 2H ₂ O + 4e → 4OHˉ Ag + Clˉ → AgCl The electrode current is proportional to the oxygen content in the gas, driven by analog conversion and decoding, and displays the percentage of oxygen through a digital screen.

• 1. Determining oxygen content in the environment of industrial and mining enterprises, cabins, tunnels, variable pressure suction nitrogen machines, oxygen generators, chemical, and fertilizer industrial gases is amazingly effective in avoiding system explosions due to oxygen in the production process and preventing room interest accidents in hypoxic environments.
• 2. The oxygen content in the exhaust gas of the internal combustion engine and the oxygen content in the flue gas is detected to achieve reasonable combustion control and save fuel.
• 3.Oxygen content determination is carried out in the atmosphere storage of grains, fruits, vegetables, tobacco, Chinese herbal medicines, tea leaves, dried fruits, etc.
• 4. Analysis of oxygen content in ventilators, anesthesia machines, hyperbaric oxygen chambers, infant incubators, and aerospace and diving operations in the medical business.
• 5. It is essential experimental equipment for physical chemistry, biology, and other experiments in secondary schools, colleges and universities, and medical schools. 6. It is suitable for determining oxygen content in the meteorological department electrolysis hydrogen production, air separation oxygen production, nitrogen production, and pharmaceutical factory injection quality inspection.
