C. Testing Principles:

1.     The tester is composed of an air source with an adjustable flow rate, a standard human head model, an inspiratory and expiratory circuit system, and a respiratory resistance measurement system.

2.     A special air path conversion element is adopted to ensure that the inspiratory and expiratory circuit system are easy to be replaced.

3.     Digital display of respiratory resistance with zero point correction, accuracy correction, and over-range alert function.

4.     A standard flow meter is adopted to ensure flow control accuracy.

5.     Siemens touch screen and PLC are emplaced to achieve real-time detection and output of pressure control and respiratory resistance test data.

6.     Thermal printer is adapted to print the respiratory resistance test report

7.     Delta inverter
