Helium Leak Testing Equipment For Automotive Air Conditioning Pipeline
Product information:
This system is a vacuum chamber type (helium filled in chamber) helium leak detection system, which is specially designed for leak detection of automotive air conditioning pipelines.
Why helium gas is used for leak test:
Only 5 ppm of helium gas exists in the atmosphere. It is less affected by the background of test environment;
Helium is safe inert gas without toxicity and explosiveness;
Because of its small molecule size, helium can penetrate through leaks easily;
It is almost not contained in the gas released from the tested part
