Coarse Leak Testing Instrument

一、Main Uses

- **Medical Device Packaging Inspection**: The Gross Leak Tester can be used for the sealing performance testing of various medical device packages, such as trays and combined packages, ensuring that the packages will not leak and cause product contamination during transportation and storage. The instrument can also be used to detect key indicators such as the pressure - resistance of the package, heat - sealing quality, and the bursting pressure of the entire package. - **Bottle Cap Sealing Performance Testing**: It is suitable for the sealing performance testing of various plastic anti - theft bottle caps, ensuring that the bottle caps can effectively prevent liquid leakage after being sealed. - **Bottle Body Sealing and Compression Resistance Testing**: It can be used for the testing of the sealing, compression resistance, and durability of various bottle bodies, providing quality assurance for bottle body design and production. - **Soft Tube Testing**: It is suitable for the sealing performance testing of soft tube packages such as various toiletries, medicinal ointments, and food packaging. - **Other Applications**: It can also be used for the sealing performance testing of aerosol valves and the pressure - resistance testing of blister packages.

二、Compliance Standards

YY/T 0681.5 - 2010, etc.

三、Technical Parameters

- **Testing Range**: Suitable for the gross leak testing under internal pressure of various packages, and the testing pressure range can be customized according to requirements. - **Testing Principle**: Based on the positive - pressure testing principle, a certain pressure is applied to the inside of the package, and it is determined whether there is a gross leak by observing whether bubbles are generated on the outside. - **Automated Control**: Equipped with a PLC industrial control program, which can accurately control the pressure and time, and automatically complete the experiment after setting the test pressure and time. - **Ease of Operation**: With a touch - screen operation interface, it is highly user - friendly and simple to operate. - **Testing Accuracy**: The testing error is usually within ±1%, ensuring the accuracy of test results. - **Constant Pressure Time**: The constant pressure time can be set through the touch - screen, with a range of 1 - 9999 seconds. - **Air Source Interface**: Usually equipped with a Φ6mm polyurethane tube and an 8mm interface for easy connection to the air source. - **External Dimensions**: The instrument dimensions may vary depending on the model but are usually compact for easy placement and operation. For example, the external dimensions of some models may be 420mm(L)×290mm(W)×280mm(H). - **Standard Configuration**: Usually includes the main unit, a puncture device, a test container, etc. - **Optional Accessories**: Non - standard devices such as a standard test rack, a three - side testing fixture, a constraint plate testing fixture, and an anti - theft bottle cap removal fixture can be selected as needed.
