This is a high-concentration oxygen meter for clean gas that utilizes the current characteristics of zirconia.
The FG series high-concentration O2 meter is a clean gas high-concentration oxygen meter that utilizes the limiting current characteristics of zirconia. Unlike the concentration cell method, which requires a reference gas, it is not affected by the surrounding atmosphere. It allows for long-term stable measurements and is compact and lightweight. We offer the FG-IIUX with a measurement range of 0 to 95% O2 and the FG-IIU-100R with a range of 0 to 25% O2. For more details, please contact us or refer to the catalog.

Company information
Gas concentration meters may be products that most people are not familiar with, but they are actually utilized very close to us. For example, in the medical field, they are necessary for managing the oxygen concentration in ventilators. In bags of snacks and food, nitrogen is filled to prevent oxidation, and gas concentration management is essential for that sealing process as well. Additionally, their role is expanding in recent years for environmental conservation, such as analyzing vehicle exhaust gases and managing combustion in incineration plants. Daiichi Thermal Research aims to contribute to the Earth, people, and society by continuously developing high-quality gas concentration meters that play such important roles.
