This paper introduces the importance and methods of airtightness testing for outdoor cameras. It needs to be waterproof, dustproof, etc. Airtightness testing is a key means to verify the sealing performance, including direct pressure method and quantitative method. Precision Industrial Technology provides a complete testing system, covering parameter setting, product fixation, automated testing and data acquisition, production traceability and other aspects of its solutions due to a variety of advantages into the industry's first choice.

This article introduces Jingcheng Engineering's airtight real water leakage tester JC-WH500, which combines qualitative detection and localization detection, and makes the leakage point visualized in the form of bubbles by establishing a pressure difference between inside and outside the product and placing it in water. It supports three modes of positive pressure, negative pressure and mixed positive and negative pressure, and can simulate a variety of waterproofing levels. It is suitable for smart wearable devices, automotive lamps, medical devices and many other industries, which effectively improves the testing efficiency and solves the pain points of engineers.
