Test Principle Firstly submerge the specimen in the water in the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen. The seal property can be obtained by observing the steady progression of bubbles from the specimen or observing how the specimen expands and restores to its original shape after vacuum release.

Y110 Oxygen Permeability Analyzer to test the oxygen transmission rate (OTR) of films or sheets materials.

GBD-B Pendulum Impact Tester test the impact resistance of various films, metallic foil and so on, widely used in industrial and mining enterprises, laboratory, scientific research, teaching, inspection agency and so on.

packaging barrier film water vapor transmission rate test also called moisture transmission rate test and WVTR

N900 Air Permeability Analyzer to test the air permeability of many textile, including technical fabric, non-woven and breathable textile products.  

The respiratory resistance tester is suitable for determining the inhalation resistance and exhalation resistance under the regulations of respirators and masks, and for the related testing and inspection of ordinary mask products by the national labor protection equipment inspection agency manufacturer.

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.
