Membrane permeability tester for battery separator, thin, flat film composite polymer materials and related products and barrier permeability test, the battery separator performance testing, application selection, polymer materials essential to research work in the importance of testing equipment. 

 Characteristics of membrane permeability tester 
 BTY-B1 upgraded products, the test is more accurate, more flexible model 
 Fashion design, new structural materials with high-tech 
 Across the wet insulation using the latest technology, the more stable and consistent test conditions 
 Membrane permeability tester can select the test mode of experience, highlighting the flexibility test 
 Test program options: automatic, manual intervention 
 Pressure testing theory, the standard classical, widely used 
 High-precision pressure sensor, data standards, high efficiency 
 Test temperature and humidity display, data graphic display, test at a glance 
 Testing new, close to the actual environment 
 Computer automatic control, software function expansion, more friendly and human-computer interaction 
 Investigation with the error correction system and inhibit the function of temperature drift and error repair 
 Test documents can be easily stored, query, print etc.; test report complete 
 Safety overload strong, and has software and hardware double overload protection 

 Membrane permeability tester principle 
 At a certain temperature and humidity on both sides of the specimen to maintain a certain gas pressure, low pressure side of the sample by measuring the gas pressure 
 Changes in order to estimate the amount of permeability and permeability coefficient. 

 Membrane permeability tester testing Introduction 
 After the trial began, the system automatically ventilation pressure with time in real time on a computer screen display, when the system reaches 
 System default or stop condition, the test stops, and then the operator needs to determine whether or test report issued by the 
 Its data operations.
