NVH Leakage Tester

This Automotive NVH Air Leakage Tester can accurately monitor the amount of gas entering or escaping the vehicle cabin, measuring the gas leakage rate under both positive and negative pressure conditions. This equipment has become an industry standard for air tightness testing among international automobile manufacturers and is an essential tool for guiding automotive air tightness design.

The vehicle air tightness testing bench is suitable for air tightness testing at different stages of new model development, providing accurate data support for both body-in-white and complete vehicle air tightness. It can provide various gas flow rates to the air vents, meeting different testing needs.

Features:

The vehicle air tightness testing bench not only helps automobile manufacturers improve product quality but also significantly enhances user driving experience and safety. Through rigorous air tightness testing, it can effectively prevent noise pollution, air pollution, and water ingress, providing users with a more comfortable and safe driving environment. 

Body-in-white Static Gas Leakage Test

Detects the basic air tightness of the car without external trim and accessories.
