In simultaneous-comparison method, two works are compared simultaneously. It cancels out the error factors such as temperature changes and deformation, achieving highly accurate leak test. However, when the two works have the same amount of leaks, the works could falsely Pass the test. So, the method is not recommended unless Fail rate of the works is extremely low. In Multi-comparison method, on the other hand, the work is compared with the master and also with another work in one test cycle. This minimizes false Pass judgments when the works have the same amount of leaks, realizing leak test of high accuracy.

When the work temperature is higher than the ambient temperature in such a case as after washing process, the temperature change of the work as a result of thermal exchange with the clamp fixture affects the leak measurement. To cope with it, the measured value can be compensated using the correlation between the differential pressure change and work temperature that causes measurement errors. The Temperature Compensation realizes highly accurate leak tests and reduces false rejects.

Master Chamber is a standard master for Master-comparison leak test that was developed to solve the problem of maintaining master parts. 〇Overview The differential pressure leak tester applies test pressure to the work and the master, and it detects leaks based on the differential pressure between the work and the master. Instead of the traditional method that uses a work without leak as the master, standard Master Chambers that are stable over time and easy to install are now widely used. In particular, when used in conjunction with Mastering, adjustments become easier, and the high reproducibility characteristics of the Master Chambers improve detection accuracy.
