FAQ

(1) What is this product?

The Mobile Phone Air Tightness Tester is a precision device used to evaluate smartphone sealing performance. It detects micro-leakage by applying controlled air pressure and monitoring pressure changes with high-accuracy sensors. The system provides quantitative leakage data and pass/fail judgment, making it suitable for both laboratory testing and production quality control.

(2) What is this product used for?

It is mainly used to verify waterproof performance and sealing integrity of smartphones, including housings, speaker modules, and sealing interfaces. It supports IP67/IP68 testing requirements and is widely applied in production lines and R&D. The system improves inspection efficiency and reduces defective products reaching the market.

(3) What is the working principle of this product?

The tester operates mainly on the differential pressure method. After pressurization, the system compares pressure changes between the test sample and reference chamber. High-sensitivity sensors detect leakage based on pressure deviation. Some models also support direct pressure or flow-based detection for specific applications.

(4) Why is this product important?

It ensures product reliability by detecting sealing defects before shipment. Even small leaks can cause water damage and product failure. The tester helps manufacturers meet IP standards, reduce warranty costs, and improve quality control through accurate and repeatable non-destructive testing.
