product description This product is based on the principle of water vapor transmission test by cup method and designed and manufactured with reference to ASTM E96, standard, providing a wide range and high efficiency water vapor transmission rate test for low, medium and high water vapor barrier materials.It is suitable for water vapor transmission performance testing of films, sheets, papers, fabrics, nonwovens and related materials in the fields of food, pharmaceuticals, medical devices, daily chemicals, etc.    

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.

OTH-150DJ is used to test the performance of materials in various environments and test the heat resistance, cold resistance, dry resistance and humidity resistance of various materials. It is suitable for quality testing of products such as electronics, electrical appliances, mobile phones, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical care, and aerospace.  

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.

  GBB-A3 Heat Sealing Tester Product Introduction GBB-A3 heat sealing tester accurately measures heat sealing temperature, time, pressure and other performance parameters of lid films for jelly cups, yogurt cups, coffee capsules, instant noodle buckets, meal boxes, medical blister packs and other food & pharmaceutical packages. Optimal sealing conditions can be confirmed precisely by testing sealing properties of different materials. Testing Principle Install matched fixture on the lower support plate and place sample steadily. Set sealing temperature, time and pressure as required, then start the device. The upper fixture descends to complete sealing. In manual mode, step on foot switch to press sealing cutter with fixed sealing duration. In automatic mode, upper and lower cutters perform cyclic sealing automatically according to preset parameters.

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.

Didital thickness tester is used to make thickness measuring or comparative measuring of plastic film, thin sheet, paper and so on.

Water vapor permeability analyzer using infrared sensor is to test the water vapor transmission rate (WVTR) of films or sheets materials. Ideal for high barrier materials like Aluminium foil.

Application W413 2.0 water vapor permeability tester is designed to test the water vapor transmission rate (WVTR) of films or sheets materials.
