Detection principle of protective mask breathing resistance tester:
1. The instrument consists of a breathing air source that can adjust the flow rate, a human head mold specified by the standard, an inhalation and exhalation pipeline system, and a respiratory resistance measurement system.
2. The use of special air path conversion elements ensures that the exhalation and inhalation systems can be replaced easily and quickly.
3. Digital display of respiratory resistance, with zero point correction, accuracy correction and over-range alarm function.
4. using standard flowmeter, high flow control accuracy.
5. Computer control and acquisition system Realize the control of pressure, the control of breathing frequency and the real-time detection and output of test data of respiratory resistance.
