What is a Leak tester?

A leak tester is a device used to detect leaks and ensure the airtightness of products or components. It is commonly used in industries such as automotive, medical devices, home appliances, and energy. For example, it checks for leaks in engine parts, fuel tanks, or HVAC systems in vehicles, ensuring that joints or pipes are sealed properly. The leak tester uses pressurized air or gas to detect leaks and measures slight pressure changes with high accuracy to identify the location and size of the leak. Methods such as pressure decay, helium leak, and vacuum testing are employed, depending on the application and required precision. It plays a crucial role in ensuring product safety and quality control.

Application of Leak tester

１．Automotive Industry Example
In the automotive industry, leak testers are used to ensure that components like fuel tanks and engine cooling systems are properly sealed. For instance, a slight crack in a fuel tank could cause fuel leaks, impacting safety. Leak testers apply pressure to check for any signs of leakage.
２．Medical Devices Example
In medical devices, catheters or IV tubes that are inserted into the body must be airtight. Leak testers are used to conduct strict leak tests to ensure that these products do not leak fluids during use, ensuring patient safety.
３．Home Appliances Example
Leak testers are used in refrigerators and air conditioners to check for leaks in the refrigerant circuit. Leaks in refrigerant gas can reduce cooling performance and harm the environment, so leak testing during manufacturing ensures product reliability and safety.
４．Energy Industry Example
In the energy sector, equipment like gas pipelines and pressure vessels are tested for gas or liquid leaks, as leaks could lead to serious accidents. Regular leak testing ensures the safety of these systems.
