Product Brief The N600C Carbon Paper Air Permeability Rate Tester is designed and developed in accordance with GB/T 20042.7-2014. Adopting the differential pressure method as its testing principle, it is professionally used for measuring the air permeability rate of various types of carbon paper for proton exchange membrane fuel cells (PEMFC). Testing Principle Based on the differential pressure method, the sample is placed between two fixtures, forming a constant differential pressure on both sides of the sample. Driven by the differential pressure, gas flows from the high-pressure side through the sample to the low-pressure side. The air permeability rate of the carbon paper is calculated based on the transmission flow rate, sample thickness, test area, and test differential pressure.

    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.

Introduction Based on the test principle of the differential pressure method, N530 is designed with reference to the GB/T 1038 standard and used to test the gas transmission rate (quantity) of film or sheet materials.

Oxygen transmission rate (OTR) is the measurement of the amount of oxygen gas that passes through a substance over a given period. It is mostly carried out on non-porous materials, where the mode of transport is diffusion, but there are a growing number of applications where the transmission rate also depends on flow through apertures of some description.
