STM-C

Function

Sealing performance testing of containers such as bags, bottles, tubes, cans, boxes, etc.

Principle

Vacuumize the vacuum chamber to create an internal and external pressure difference in the sample immersed in water, observe the escape of gas from the sample into the water (bubbles will be magnified 5-10 times), and observe the recovery of the sample after the vacuum is released to determine the sealing performance of the sample.

Execution standards

GB/T 15171、ASTM D3078。

technical feature

• Parameterized setting of vacuum degree and vacuum time;
• Imported pneumatic components create a smooth and fast vacuum environment;
• Automatic constant pressure, maintaining precise and stable vacuum degree;
• Microcomputer intelligent control, automated testing: automatic pressure relief, automatic end, pressure relief recovery;
• Flexible printing of test data: group or single test printing, including test evaluation, test vacuum degree, and constant pressure time;
• Color LCD display screen.
