Q&A: How Can Domestic Air-Tightness Leak Detectors Replace Imported Brands? Advantages of Domestic Manufacturers and Validation Methods

This article explores the feasibility of replacing imported brands with domestically produced airtightness leak detectors. The article notes that conventional air leak testing can be evaluated for substitution through validation under identical operating conditions, while extreme scenarios require separate verification; the basis for substitution is actual test results rather than parameter tables. The advantages of domestically produced equipment lie in cost, delivery, customization, and localized services. It is recommended to first conduct pilot projects followed by a phased replacement, using testing capabilities, stability, and long-term service as selection criteria.
