Oxygen meter for vacuum devices and vacuum furnaces [Zirconia type oxygen meter]
"I want to measure oxygen in real-time in a vacuum... I want to manage combustion to reduce fuel costs..." We will solve such problems! *Case study introduction*
Atmospheric pressure is 1 atmosphere (1013.25 hPa). A space with lower pressure than this atmospheric pressure is called a vacuum. By creating a vacuum, it is possible to prevent the oxidation of processed materials, which is why vacuum devices and vacuum furnaces are used in many material product processes, etc. Our zirconia-based oxygen meter can measure a range of 10×-30 atm O2, starting from ppm O2 concentration. 【Features】 ○ Can be directly inserted into glove boxes, vacuum furnaces, and small sealed containers or piping where sampling is difficult. ○ Capable of measuring O2 partial pressure under reduced pressure of 1×10-3 Pa (1×10-5 Torr). ○ Easy maintenance due to its simple structure. 【Specifications】 ○ Flange sizes: VF25, NW40, NW25, etc. ○ Installation: Horizontal to vertical, with the above flanges prepared by the customer. ○ Measurement range: 1 ppm to 100% O2, 1 to 1×10-30 atm O2. 【What can be solved with the zirconia-based oxygen meter】 ● I want to measure the atmosphere inside the furnace to improve quality. ● I want to measure the oxygen concentration in a vacuum. ● I want to manage combustion to reduce fuel costs. ● I want to manage the concentration of clean gases in PSA, gas production equipment, etc. *For more details, please download the catalog or feel free to contact us!

Gas Analyzers may be unfamiliar products to most people, but they are actually used in places very close to our everyday lives. For example, in medical settings they are needed to manage the oxygen concentration in ventilators. Bags of snacks and food are filled with nitrogen to prevent oxidation, and gas concentration management is essential for controlling that filling process as well. In addition, they are used for environmental protection purposes such as analyzing vehicle exhaust gas and managing combustion at incineration plants, and their role has been expanding in recent years. By continuing to develop high-quality gas analyzers that fulfill these important roles, Daiichi Nekken aims to contribute to the earth, people, and society.
