4O2-LF Electrochemical Oxygen Gas Sensor For Semiconductor Manufacturing Food Modified Atmosphere Packaging
Product Uses:
3D Metal Powder Printing: It is used to monitor the residual oxygen concentration in inert gases (such as argon) in real - time, which can prevent metal powders such as titanium and aluminum from oxidizing during high - temperature printing, avoid the increase of the porosity of printed parts and the decrease of strength, and eliminate the risk of dust explosion.
Semiconductor Manufacturing: It is used to monitor the oxygen impurities in high - purity nitrogen/argon during wafer processing, which can prevent the surface of silicon wafers from oxidizing and ensure the yield of deposition (CVD/PVD), etching and other processes and the performance of devices.
Lithium - battery Production: It is used to detect the oxygen concentration in the electrolyte injection and battery packaging environment, which can avoid the decomposition of the electrolyte (such as EC/DMC) and the oxidation of the positive electrode material (such as NCM), and improve the safety and cycle life of the battery.
Food Modified Atmosphere Packaging: It is used to monitor the residual oxygen in nitrogen - filled or mixed gases, which can extend the shelf - life of high - value foods (such as fine - grade coffee and nuts) and inhibit the oxidation of fat and the reproduction of microorganisms.
Pharmaceutical and Biological Preparations: In the aseptic filling process, it is used to ensure that the oxygen concentration is <10ppm to prevent oxidation or microbial contamination. In the freeze - drying process.
Aerospace: It is used to monitor the trace oxygen in the vacuum furnace to prevent the surface of titanium alloy/composite materials from embrittlement during high - temperature treatment and ensure that the material performance meets the standard. It can also monitor the oxygen concentration in inert gases (such as argon) to prevent sodium from reacting with oxygen to form corrosive oxides and ensure the safety of the reactor.
High - purity Material Preparation: It is used to control the oxygen content in protective gases to avoid the influence of oxygen impurity doping on the conductivity and purity of single - crystal silicon, superconducting materials, etc.
Electronic Special Gas Production: It is used to detect the oxygen impurities in high - purity electronic special gases such as helium and neon to meet the gas standards of the semiconductor industry (such as SEMI level) and ensure the purity of process gases.
Cultural Relic Protection: It is used to control the oxygen concentration of inert gases (such as nitrogen) in airtight display cabinets to prevent cultural relics such as bronze ware and ancient books from oxidizing and extend their preservation period.
Power Industry: It is used to monitor the oxygen impurities in sulfur hexafluoride (SF₆) insulating gas to prevent the generation of toxic sulfur oxides under high - voltage arcs and ensure the safety of equipment.
Product Features:
Wide Measuring Range: Some models can measure the oxygen concentration in the full - concentration range of 0 - 100%VOL, with a wider application range.
High - resolution Measurement: It has a globally leading resolution of 0.5ppm, which can accurately monitor the ultra - low - concentration oxygen environment.
Fast Response: The T90 response time is ≤15s, which can quickly detect the change of oxygen concentration and give an alarm in time
Good Stability: The long - term output drift is <5% signal/year, which can maintain stable performance in different environments.
Environmental Friendliness: It is lead - free, in line with the RoHS standard, and is suitable for applications in food, medicine and other industries that are sensitive to heavy metal content.
Convenient Storage and Transportation: It adopts an innovative design, and there is no need for inert gas protection during transportation and storage, which greatly simplifies the supply chain management.
Long Service Life: The expected service life in clean air can be up to 5 years, which significantly reduces the replacement frequency and maintenance cost, and effectively reduces the comprehensive use cost.
Low Power Consumption: Compared with traditional zirconia sensors, the power consumption is significantly reduced, which is more suitable for applications that require long - term continuous monitoring.
Small and Light: The housing is made of ABS material, weighing about 5g, which is small in size and light in weight, and is easy to install and use in various detection equipment
