Product introduction: The vacuum box type helium leak detection equipment is a kind of equipment specifically used to detect the leakage situation in the sealed system. Its working principle is to place the component to be detected in the vacuum box, and then use the vacuum pump to suck the inside of the box into a vacuum state. Next, helium gas is injected into the box. Because helium gas has extremely small molecule diameter and good permeability, it will enter the vacuum box through any existing leak points.
