N900 Air Permeability Tester For Textile Fabrics

Benefits

• High-precision sensor replaces the traditional water column differential pressure test, providing unparalleled accuracy.
• Suitable for testing various textile fabrics, including technical fabrics, non-woven, and other breathable textile products.
• Automatic cylinder control ensures quick sample fixation for accelerated testing.
• Pressure is easily adjustable with automatic measurement and result calculation.
• Built-in micro-control system, efficiently calculates test data, prints results, and eliminates the need for manual conversion.
• Mainframe comes up with a colour touch screen, eliminating the necessity for an external computer.
• Users can seamlessly observe the permeability rate of the sample in real-time.
• Professional software has a simple interface that displays real-time test data (air permeability, variation coefficient, and other parameters).
• Supports diverse unit conversions: mm/s, l/(dm^2,min), l/(m^2.s), m^3(m^2.min), m^3/(m^2.h). cfm, cm^3/(cm^2.h), ml/s, ml/min, l/s, l/min).
• Automatic generation of standardised test reports, including sample name, specifications, serial number, and airflow direction through the fabric.

• Knitted fabrics, nonwoven fabrics, parachute, sail, space suit, woven fabrics.
