Working Principle
The Window Air Tightness Tester simulates real environmental wind pressure conditions by generating controlled positive and negative air pressure across the window or door specimen.
During the test, precision pressure sensors and airflow measurement devices continuously monitor pressure differences and air leakage rates. The intelligent software automatically records, analyzes, and calculates key performance indicators, including:
* Air Leakage Rate
* Air Permeability
* Pressure Difference
* Air Flow Volume
* Airtightness Classification
* Pressure-Time Curves
* Pass/Fail Evaluation
The complete testing process is automated, ensuring accurate and repeatable results that comply with international testing standards.
