This article is the 2026 Guide to Selecting Leak Testing Equipment published by Jingcheng Engineering. Its central argument is that the selection process should shift from a “precision-only” approach to one that prioritizes system capabilities that meet the actual needs of production lines. The article analyzes industry trends against the backdrop of accelerating domestic substitution, compares the strengths and weaknesses of international brands and domestic manufacturers, and—using Jingcheng Engineering’s JCGK as an example—emphasizes three core dimensions: full pressure coverage, automation integration, and mass-production stability. Ultimately, it proposes a selection logic based on matching solutions according to pressure levels and prioritizing integrated system solutions.

This article systematically analyzes the logic behind pressure selection for airtightness testing, covering four pressure ranges: low pressure (0–100 kPa), medium pressure (100–500 kPa), high pressure (>500 kPa), and ultra-high pressure (>1 MPa), covering core application scenarios such as consumer electronics, new energy vehicles, and hydrogen energy. It also introduces JCGK’s comprehensive pressure testing solutions and their key advantages.

This article introduces the Water Pressure Resistance Tester for Waterproof and Breathable Membranes launched by JCGK. Utilizing a "real water coating + pneumatic loading" method to simulate real-world operating conditions, it provides an intuitive assessment of the water-blocking capabilities of membrane materials such as ePTFE. The device covers the membrane surface with water and applies pressure, displaying real-time leakage data. It supports high-definition observation of failure phenomena such as water droplets, wetting, and pinholes on the membrane surface, and allows for photo and video recording for archiving. It is suitable for R&D validation and mass quality inspection in industries such as new energy, automotive electronics, and consumer electronics.
