What is an airtight leak detector?

Air tightness leak detector is an important equipment in manufacturing industry, which can help enterprises ensure the quality and safety of products. It is used to detect whether there is any leakage in various seals, containers, pipelines, etc. It is also called air tightness testing equipment, waterproof testing machine, air tightness leak detector and air tightness detector to judge the sealing performance by filling gas or liquid into the tested product and detecting the leakage.

The purpose of air tightness leak detection is to check whether the air tightness design of the product is reasonable.

Check whether the interface and joint of the product are completely sealed.

Evaluate the product's ability to meet the corresponding level of intellectual property protection.

Ensure the air tightness and protective performance of the product during use.

JCGK air tightness leak detector, test product: automotive wiring harness.

There are mainly the following testing methods: pressure difference method: put the tested product in a closed container, fill the container with gas or liquid, and detect the pressure difference inside and outside the container. Differential pressure method is also called pressure drop method.

Vacuum attenuation method: put the tested product in a vacuum environment to detect the leakage of gas or liquid inside the tested product. Vacuum attenuation method is also called negative pressure method.

Helium leak detection method: inject helium into the tested product, and use helium leak detector to detect helium leak inside the tested product. Helium leak detection method is also called helium detection method.
