Nasal Oxygen Tube Airflow Resistance TesterNOC-02 Testing Instrument is a device used for testing the airflow resistance of nasal oxygen tubes, also known as a nasal oxygen tube airflow resistance measuring instrument, nasal oxygen tube airflow resistance test apparatus, nasal oxygen tube airflow resistance detector, etc. It complies with the testing requirements of YY/T 1543-2017 "Nasal Oxygen Tube." This equipment is suitable for all nasal oxygen tubes, whether they are standalone nasal oxygen tubes or those used in conjunction with humidifier bottles and masks. It can test indicators such as nasal oxygen tube airflow resistance, anti-collapse performance, leakage testing, pressure resistance strength, and patency.
