|product name:||Oxygen O2 gas probe|
|Measurement object:||O2 in the air|
Oxygen (chemical formula: O2), chemical formula amount: 32.00, colorless and odorless gas, the most common elemental form of oxygen element. The melting point is -218.4 ° C, and the boiling point is -183 ° C. Not easily soluble in water, about 30mL of oxygen in 1L of water. Oxygen accounts for about 21% in the air. Liquid oxygen is sky blue. Solid oxygen is a blue crystal. It is not very active at room temperature and is not easy to interact with many substances. However, it is very active at high temperatures and can directly combine with many elements, which is related to the electronegativity of oxygen atoms after fluorine.
Oxygen is the most widely distributed in nature, accounting for 48.6% of the crustal mass, and is the most abundant element. Oxygen is required for the oxidation of hydrocarbons, the treatment of wastewater, rocket propellants, and for breathing of animals and humans in aviation, aerospace and diving. Animals consume oxygen during breathing, burning and all oxidation processes, including the spoilage of organic matter. But the oxygen in the air can be continuously supplemented by photosynthesis of plants. In metal cutting and welding. It is a mixture of oxygen with a purity of 93.5% ~ 99.2% and a combustible gas (such as acetylene), which generates a flame at an extremely high temperature, thereby melting the metal. The metallurgical process cannot be separated from oxygen. Oxygen is also needed to strengthen the production of nitric and sulfuric acids. A gas of high calorific value can be obtained by blowing a mixture of oxygen and water vapor into a gasifier without using air. Medical gas is extremely important

O2气体探头应用： Application of oxygen O2 gas probe:
Petroleum and petrochemical, chemical industry, smelting plant, steel plant, mining plant, thermal power plant, pharmaceutical production workshop, environmental monitoring, fire alarm, sewage treatment, gas station monitoring, security inspection, inspection and quarantine, etc. O2气体泄露情况，当有氧气O2气体泄漏时，探测器会检测到泄漏信息，并且实时显示泄漏氧气O2气体浓度，而且及时将相关数据传输到控制器，当达到一定浓度时，控制器会提示使用者已经检测到气体泄漏，联动设备、相关人员采取相关措施，是保证环境、生产、以及生命财产安全的重要仪器。 It is mainly used to monitor the leakage of oxygen O2 gas indoors and outdoors . When there is a leak of oxygen O2 gas, the detector will detect the leakage information and display the leaked oxygen O2 gas concentration in real time, and transmit the relevant data to the controller in time. When the concentration is reached, the controller will prompt the user that a gas leak has been detected, and the associated equipment and related personnel will take relevant measures to ensure the safety of the environment, production, and life and property.
