With the development of the times and the advancement of aviation and aerospace industry technology, people's requirements for sealing performance testing technology and equipment have also reached a new level.In the civil industry, people's awareness of leaks and their requirements for leak detection and control are increasing day by day.In addition, in recent years, motorcycles, air conditioners, cars, and gas appliances have become familiar to more and more people. The hazards and disasters caused by leakage of these products have also sounded the alarm for people.

Therefore, in order to improve product quality, manufacturers use“Water leakage detection&”To find unqualified workpieces, this is commonly referred to as water inspection. This inspection process has a history of nearly a hundred years.In the mid-to-late 1970s, some developed countries with industrial technology began to study new processes and new equipment to replace water inspection - tightness detectors in order to overcome some of the disadvantages caused by the water inspection process on the follow-up operations of workpieces.

By the early 1990s, the process of using clean and dry air as the working medium to test the sealing performance of workpiece cavities, such as motorcycle engine blocks, automobile engine blocks, radiators, brake systems, evaporators, gas appliances, etc., had matured, and some corresponding testing equipment was gradually introduced.

As a result, air tightness testing equipment began to develop and grow, and tightness detectors with different functions were generated!
