N600P Paper Air Permeability Tester

Operating principle

Gurley Method: To measure the time taken to pass 100 ml of gas at a constant pressure difference of 1.23 kPa.
Schopper-Riegler Method: Select the appropriate test duration and determine the air flow rate through the sample by measuring the volume under the constant pressure difference of 1.00kPa ± 0.01kPa or 2.50 ± 0.01kPa.
Bendtsen method: At a constant pressure difference of 1.47kPa, the air flow through the test surface was recorded after clamping for 5s.

Features

• Integrate Gurley's method, Schober's method, and Bengtsen's method into one machine for users to choose freely to meet the testing needs of different users.
• The pressure difference of the instrument is adjustable in the range of 0-3 kPa, with an accuracy of 0.001 kPa, fully meeting the test pressure difference required.
• The test area can be freely converted between 10 cm² and 6.42cm² by changing the fixture.
• The sealing of the instrument is good, and the air leakage does not exceed 1.0 mL/h.
• The host is equipped with a colour touch screen, no external computer is needed, and the air permeability of the sample can be observed in real time.
• Built-in micro printer, which can print test reports in real time.
