Breathing Tube Resistance to Flow Tester
NOC-03
NOC-03 Breathing Tube Resistance to Flow Tester, designed according to ISO5367, is used to test the resistance to flow performance of breathing tubes intended for use with aneasthetic apparatus and ventilators.
Product Features
Specialty Design
Support two test methods: resistance to flow and flow resistance with bending
Extend for six test functions: airflow resistance, flatness resistance, leakage test, pressure resistance, patency and flow resistance with bending.
7-inch color touch screen control
Equipped with a high-precision pressure sensor, the output pressure can be stably controlled through the pressure knob
Adopt 15mm and 22mm double cone connector, which can meet the test requirements of double interface of breathing tube
Surge Flask is designed in accordance with test standards
Powerful data storage function, which can store more than 100,000 test record
Equipped with a micro printer, print the test results in real time
Safety Protection
Pressure over-range shutdown function effectively protects sensor
Overload protection and power-down memory functions ensure users' safety
Test Principle
Resistance to flow: Adjusting the test pressure and rated flow, record the pressure change before and after the tube is inserted (△P=P2-P1), which is the airflow resistance.
Flow resistance with bending: After completing the airflow resistance test, hang the pipe for bending test on a small diameter metal column, tie a weight to the end of the pipe to keep the breathing pipe in contact with half the circumference of the metal column, introduce air into the pipe at the rated flow marked by the manufacturer and record the pressure increase.
