- Commodity name: Respiratory Resistance Tester
It is used to measure the inspiratory resistance and expiratory resistance of respirators and masks.
The sample is worn on the test headform, and the position and tightness of the mask are adjusted to ensure the tightness of the mask and the test headform. The air pump simulates the exhalation and inhalation of a person, maintains the ventilation volume at 85 (± 1) L / min. The expiratory resistance and inspiratory resistance were measured and recorded.
● Test mode: inspiratory resistance, expiratory resistance。
● Using an Imported digital flowmeter, Accurately control the flow of expiratory and inspiratory ventilation.
● Using import micro-differential pressure sensors, accurately measure the differential pressure on both sides of the sample.
● 7-inch color high-resolution touch screen, easy to use, and can store and review test data.
● Equipped a micro-print, used to print a test report.
