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.
