CI-XT20-1 Desktop Medical Oxygen Quality Analyzer
The CI-XT20-1 Desktop Medical Oxygen Quality Detection System, developed by Shanghai ChangAi Electronic Technology Co., Ltd., is a purpose-built analytical system designed in full compliance with the Chinese Pharmacopoeia (2020 Edition) and the XGB2021-061 standard for medical oxygen. This system accurately evaluates key quality indicators of medical-grade oxygen, including: Oxygen concentration ≥ 99.5%, Carbon monoxide < 5 ppm, Carbon dioxide < 300 ppm, Moisture (water vapor) < 67 ppm. Engineered to meet GMP certification requirements, the CI-XT20-1 is ideally suited for use by local food and drug regulatory authorities for the supervision and inspection of medical oxygen production and storage processes.
