Coulometric Method
This product is designed and manufactured based on the coulometric oxygen sensor principle, in accordance with GB/T 19789, ASTM D3985 and other international standards. Equipped with high-precision imported oxygen sensor, it ensures excellent testing accuracy. It is suitable for oxygen permeability testing of films, sheets, paper, packages and related materials in food, pharmaceutical, medical device, daily chemical, photovoltaic and electronic fields, providing wide-range and high-efficiency oxygen transmission rate detection for high, medium and low oxygen barrier materials.
