N900 Textile Air Permeability Tester

N900 Textile Air Permeability Tester

 

Introduction

N900 Textile Air Permeability Tester is developed in accordance with GB/T 5453-1997 . It is a high-precision testing instrument integrating machinery, electronics and software. High-precision pressure sensors are adopted to replace the traditional water column differential pressure method for higher accuracy of test data. It features LCD display and touch screen operation. Test parameters can be set digitally for convenient and fast operation.

It is suitable for air permeability testing of various textile fabrics, including industrial fabrics, nonwovens and other breathable textile products. Through the air permeability test results of textiles, the air permeability performance of different fabrics can be compared. Meanwhile, it provides numerical reference for air permeability of special fabrics such as parachutes, sails and spacesuits.

 

Test Principle

Air permeability refers to the property of air passing through fabric. It is expressed as the rate of airflow vertically passing through the sample under specified test area, pressure drop and time conditions.

Under specified differential pressure conditions, measure the airflow volume vertically passing through the given area of the sample within a certain period of time, and calculate parameters such as air permeability.

Moisture vapor transmission rate GBPI WVTR Moisture Vapor Transmission Rate Tester
    W201 2.0 Water Vapor Transmission Rate Tester Product Introduction This product is developed, designed and manufactured based on the electrolytic test principle, in accordance with GB/T 21529, ISO15106-3 and other standards. It is used to test the water vapor transmission rate of samples under set temperature and humidity conditions. Suitable for water vapor transmission performance testing of high-barrier materials used in LCD display devices, solar cells, chip packaging, pharmaceuticals, food and other fields. Get a Free Quote Today   Test Principle W201 2.0 Water Vapor Transmission Rate Tester adopts the electrolytic method principle. The pre-processed sample is fixed in the middle of the test chamber, dividing the chamber into high-humidity and low-humidity sides. Humidified nitrogen flows on one side of the film, and dry nitrogen (carrier gas) flows at a fixed rate on the other side. Due to the humidity gradient, water vapor permeates from the high-humidity side to the low-humidity side. The water vapor passing through the sample is carried by the flowing dry nitrogen to the electrolytic sensor, and parameters such as the water vapor transmission rate of the sample are obtained through the electrical signal output by the sensor.
