Product Brief The N600P Paper & Paperboard Air Permeability Tester is custom-developed to align with standards like GB/T 458-2008 and ISO 5636. It adopts the differential pressure method as its core testing principle, and innovatively integrates three industry-common testing approaches (Gurley, Schopper, and Bendtsen) into a single device.   This tester is applicable to air permeability detection of various paper and paperboard materials, and can measure key indicators including: material air permeability, air resistance, gas transmission rate, and total gas transmission volume. Testing Principle Gurley Method   Under a constant differential pressure of 1.23 kPa, measure the time required for 100 mL of gas to pass through the sample. Schopper Method   Select a suitable test duration under a constant differential pressure (1.00 kPa±0.01 kPa or 2.50±0.01 kPa), and calculate the gas flow rate through the sample by measuring the gas volume. Bendtsen Method   After clamping the sample for 5 seconds under a constant differential pressure of 1.47 kPa, test the gas flow rate through the surface of the sample. Executed Standards GB/T 458-2008, SJ/T 10171-2016, ISO 5636-5:2003, ISO 5636-2:1984, ISO 5636-3:2013, TAPPI T460 Technical Parameters   Item Technical Parameters Test Range 0.1~10 μm/(Pa·s) Resolution 0.001 μm/(Pa·s) Differential Pressure Range 0~5 kPa Pressure Resolution 0.001 kPa Test Area 6.42 cm² or 10.0 cm² Sample Size ＞50 mm×50 mm Instrument Dimensions (L×W×H) 450 mm×400 mm×300 mm Power 100 W Power Supply 110~250 VAC, 50~60 Hz

Product Profile • The W416 2.0 Infrared Method Water Vapor Transmission Rate Tester is a high-end precision testing instrument for packaging materials, newly developed and upgraded by Guangzhou Standard International R&D Team in full compliance with the requirements of **GB/T 26253** and **ASTM F1249** standards as well as market demands. • Based on the testing principle of infrared moisture analysis sensors, it provides wide-range, high-efficiency water vapor transmission rate (WVTR) testing for high, medium and low barrier materials. • It is suitable for testing the water vapor transmission performance of films, sheets, papers, packages and other related materials in industries such as food, pharmaceuticals, medical devices, daily chemicals, photovoltaic electronics, etc. • It is an ideal offline or online configuration instrument for manufacturers in the packaging industry to test the barrier performance of packaging materials. Testing Principle The W416 2.0 Water Vapor Transmission Rate Tester adopts the infrared method principle: 1. Fix the pre-treated sample in the middle of the test chamber, dividing the chamber into a high-humidity chamber and a low-humidity chamber. 2. Compressed air flows through the high-humidity chamber, while dry nitrogen (carrier gas) flows through the low-humidity chamber at a constant flow rate. 3. Due to the humidity gradient, water vapor penetrates from the high-humidity chamber to the low-humidity chamber. 4. The water vapor passing through the sample is carried to the infrared sensor by the flowing dry nitrogen. 5. Parameters such as the sample’s water vapor transmission rate are derived from the electrical signal output by the sensor.
