Airtightness Tester

The article introduces three airtightness measurement methods: airtightness tester measurement, direct soak method and true water leakage tester measurement, and analyzes them in four dimensions: product value, accuracy requirements, production scale and application scenarios. The airtightness tester is the mainstream choice for industry, with the advantages of non-destructive, accurate and efficient; the direct soak method is intuitive but inefficient and risky; and the true water leakage tester is suitable for high-level waterproof verification and leakage point localization.
