Portable oxygen meter

Portable oxygen meterIntroduction

Portable oxygen meter is a high-performance portable measuring instrument used to measure the concentration of oxygen content in aqueous solutions. It has a measurement accuracy of microgram level, high measurement accuracy, easy operation, and effectively avoids oxygen leakage. It is particularly suitable for detecting low concentration dissolved oxygen in ultrapure water and has been widely used in the petrochemical, power, beverage, pharmaceutical, and semiconductor industries.
