Application Overview:
The direct pressure tester is a comprehensive testing instrument that fully meets the waterproof, sealing and airtightness requirements of products in various industries. It can easily handle various complex working conditions. It uses self-developed pneumatic control valves that do not generate heat, resulting in higher testing accuracy and better stability.
Detection principle: The instrument fills the tested product with compressed air under a specified pressure, then stops the inflow and maintains the pressure. During the pressure retention process, a highly sensitive pressure sensor is used to detect the pressure drop caused by leakage in the tested product, and the pressure drop value or leakage rate is calculated.
