Q&A: The higher the precision, the easier it is to misjudge? Uncovering the real stability logic of production line airtightness testing

This article exposes the "accuracy trap" in the procurement of leak tester, points out that marketing parameters such as 0.02% F.S. are misleading, and emphasizes that the detection stability depends on five system engineering factors: sensors, manifold seals, ambient temperatures, tooling and fixtures, and software algorithms. The authors propose that the selection should focus on the reading error (%rdg) and repeatability rather than full scale error, suggesting that the production line through the on-site testing to verify the performance, and that the domestic equipment in the system integration, cost-effective and service response has the strength to replace imports.
