A533 water vapor permeability analyzer is to test the water vapor transmission rate (WVTR) of films or sheets materials.

Application It is to test the filtering efficiency of particulate protective masks and medical masks and to determine the resistance of ordinary fabrics and medical protective masks to the constant flow of airflow.

Accelerated weathering tests are performed on materials by simulating ultraviolet radiation and condensation in natural sunlight to obtain results on material weathering resistance. It can simulate environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, and darkness in natural climates. By reproducing these conditions, it can be combined into a cycle and allowed to automatically complete the cycle as required.

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.

Heat Seal Tester apply to test the temperature, pressure, time and strength for heat sealing of various plastic films, composite film, aluminum foil and so on, widely used in industries of , food, pharmaceuticals, inspection agency, research institute and so on.

The coefficient of friction tester is used to test the coefficient of frictionof plastic film, thin sheet, paper and so on, widely used in packaging industry, film-making companies and packaging material inspection agencies.

GQ-300 Modified Atmosphere Refrigerator is a kind of Laboratory Refrigerator with microelectronics technology, is for making preservation experiment on fruits, vegetables, flowers and plants in modified atmosphere conditions, and keeps them fresh by controlling concentration of O2, N2, CO2, and C2H4 and the temperature and humidity in the boxes. It is widely used in industries of microorganisms, environmental, food, research institute and so on.

Product introduction The W303 WVTR tester is designed and produced based on the test principle of weight method (weight reduction) and as per the standards of GB/T 1037 and ASTM E96, etc. It is suitable to measure the water permeability performance of film, sheets, papers, packagings and other related materials in the industries of food, pharmaceutical, medical equipment, daily chemicals, Photovoltaic electronics, etc, providing wide range and high efficiency water vapor transmittance detection for high, medium and low water vapor barrier materials.  

1 Function Ozone in the atmosphere is very little, while it’s a major factor in rubber cracking, the product simulate and enhance atmospheric ozone condition to study the role of ozone on the rubber, and to rapid identificate and evaluate rubber resistance for ozone aging and anti-ozone agent protection.
