OVERVIEW

Applicable Industry:
Tire air tightness tester applies to the plastic film, complex film, sheet of gas at various temperatures through the air permeability, solubility coefficient, diffusion coefficient and permeability coefficient of determination.
 
Technical Characteristics:

• The principle of differential pressure method, GB, ISO, ASTM and other global standards-compliant
• Three-cavity independent testing can be issued by each chamber of the independent data, the average of the combination of cavity statistics
• The world's most high-precision, high vacuum, impartial third party data, the objective
• Peripheral temperature control device can be any temperature within the range of 5 ~ 95 °C, the penetration test
• Humidity generating device optional test is easy to realize differential pressure method under different

humidity conditions, to better simulate real life

• Buy the world's well-known components, stable and reliable performance
• Conventional, non-standard double test mode selection
• Super software support, solubility, diffusion and permeability coefficient automatic calculation of an Excel

format, the graphical display

• The amount of ventilation, diffusion coefficient, solubility coefficient and permeability coefficient, any

conditions for fitting function,   the only global

• Can be easily obtained -273 °C ~ 200 C Material permeability, permeability coefficient, solubility

coefficient and diffusion coefficient

• Operating intelligent test, the test process automation
• Equipment performance is ultra stable, continuous operation, and more to improve test efficiency
• Data reproducibility, human operating error
• Low systematic error of the blank test, the overall performance is better than similar products at home

and abroad

• Reference diaphragm calibration, easy to operate
