N900 Air Permeability Tester For Textile Fabrics

N900 Air Permeability Tester For Textile Fabrics

Manufactured by GBPI Testing Instruments

Suitable for testing the air permeability of various textile fabrics, this high precision experiment-usage testing instrument can test multiple sets of data continuously. It allows for querying, deleting groups of experimental results, and efficient report printing.

Key components include an imported pressure sensor, turbofan, air cylinder, and motor, enabling it to test the performance of air pass through the fabric sample. The N900 stands out for its efficiency, precision, and user-friendly interface, enabling you to elevate your fabric testing capabilities.

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.

Applications

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