Verifying the airtightness tester with a single strand of hair is a simple yet effective method, which aids in assessing the stability and detection sensitivity of the airtightness tester over extended periods of use.

In the testing of aluminum alloy die castings in the automotive industry, we can utilize the Longshi Technology LS4000 dual-channel airtightness tester in conjunction with dual-channel airtightness testing fixtures for the experiment.

Firstly, a single hair is placed under the tested product, and then the top and bottom molds of the sealing mold are pressed down to form a sealed cavity. Subsequently, the air tightness tester is connected to the sealed cavity, and gas pressure is filled into it. After a period of stable pressure, the testing phase begins. The air tightness tester can monitor the air tightness of the sealed cavity, including the leakage of the gas and its changing trend.

By observing the readings and trends of the airtightness tester, we can determine the airtightness performance of the product being tested. If the readings from the airtightness tester remain stable or show minimal changes, it indicates that the product's airtightness is good; otherwise, there may be airtightness issues. Through this verification method, we can assess the quality and stability levels of the product being tested, enhancing product

Enhanced Reliability and Security.
