Paper and Cardboard Air Permeability Tester N600P
The N600P Air Permeability Tester is designed to measure the air permeability of paper and cardboard using three established methods: Gurley, Schopper-Riegler, and Bendtsen. This versatile instrument ensures accurate and reliable results for a variety of materials and applications.
Operating Principle
-
Gurley Method: Measures the time taken for 100ml of gas to pass through the sample at a constant pressure difference of 1.23 kPa.
-
Schopper-Riegler Method: Determines the air flow rate through the sample by measuring the volume under a constant pressure difference of 1.00 kPa ± 0.01 kPa or 2.50 ± 0.01 kPa over a selected test duration.
-
Bendtsen Method: Records the air flow through the test surface at a constant pressure difference of 1.47 kPa after clamping for 5 seconds.
Specifications
Features
-
Versatile Testing: Integrates Gurley, Schopper-Riegler, and Bendtsen methods, allowing users to select the method that best suits their testing needs.
-
Adjustable Pressure Difference: The pressure difference can be adjusted within the range of 0~3 kPa with an accuracy of 0.001 kPa, meeting the requirements of all three testing methods.
-
Flexible Test Area: The test area can be switched between 10.0 cm² and 6.42 cm² by changing the fixture.
-
High Sealing Efficiency: Ensures minimal air leakage, not exceeding 1.0 mL/h.
-
User-Friendly Interface: Features a color touch screen, eliminating the need for an external computer and allowing real-time observation of air permeability.
-
Built-In Micro Printer: Prints test reports in real time for immediate results.
Applications
-
Insulating Paper: Measures the air permeability of transformer insulation cardboard, green shell paper, cable paper, etc.
-
Wrapping Paper: Determines the air permeability of kraft paper, paper bag paper, food packaging paper, moisture-proof paper, paraffin paper, etc.
-
Fiber Paper: Measures the air permeability of wound paper, impregnated paper, laminate, capacitor paper, high-temperature fiber paper, etc.
-
Filter Paper: Evaluates the air permeability of industrial filter cloth (filter paper), qualitative filter paper, quantitative filter paper, etc.
-
Other Materials: Suitable for testing alkaline battery separators (nylon felt, non-woven fabrics, tissue paper, and other microporous membranes) and other similar materials.
