Through the monitoring and processing of the pressure inside the low pressure side, the barrier parameters of the test samples can be obtained. It fully complies with GB1038, ASTM D1434 and other standards.Reference standardsYBB 00082003, GB/T 1038, GB/T7755.1, ASTM D1434,ISO 2556,ISO 15105-1,JIS K7126-AConfigurationStandard configuration: host, constant temperature controller, computer, professional software, special sampler, vacuum grease, fast quantitative filter paper, vacuum pumpOptional: sampling blade, vacuum grease, vacuum pump oil, fast quantitative filter paper, humidity generatorNote: The air source of the machine is ф 6mm polyurethane pipe; gas source and distilled water are provided by usersThe device appearance diagram shows the standard device appearance, the appearance of customized devices may vary.FAQAre you a manufacturer or trading company?We are the manufacturer and trading combo, which specialize in material testing instruments such as plastic package, medical device, facial mask, protective clothing and pharmaceutical package, etc. We located in Jinan, Shandong, China.Do you have any certificate?We have 22 utility model patents and 17 software copyright certificates.How about the installation?The user's manual specifies the installation requirements with details.
