Introduction of air tightness leak detector

Air tightness leak detector (hereinafter referred to as leak detector) is mainly used to detect the water tightness of products or parts to ensure that there are no defects of water leakage and air leakage, so it is also called waterproof detection equipment, air tightness detector and air tightness tester.

Application of Jingcheng engineering air tightness leak detector in production line

The working principle of air tightness leak detector is to fill the product with compressed air or helium, and then measure the pressure or flow. If the product leaks, the pressure or flow will drop. The air tightness detector can use various methods to detect leakage, including direct pressure method, negative pressure method, volume quantification method, flow method and pressure difference method.

The performance of air tightness leak detector is usually measured by leakage rate. The leakage rate is the volume of gas passing through the test product per unit time. The lower the leakage rate, the better the air tightness.
