The micro-pressure E/P regulator can easily control micro-low pressure with a voltage of 0 to 5 V to generate a large flow.

Using the Bypass Circuit Unit reduces the test time of large-volume works. Air Leak Testers can control the air operated valves of the Bypass Circuit Unit. Single, Dual and Triple valves are available. Select according to the shape and volume of the work. Bypass Circuit Unit compatible with E/P regulator is also available.

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.

Prevents foreign matter such as water, oil, and dust in the works and piping from entering the leak tester, thereby preventing malfunctions and quality deterioration. We recommend especially when performing both water dunk and air leak tests. It can be used at test pressures of up to 4.9 MPa.

It demonstrates its effectiveness in pneumatic circuits where leak is not allowed. When switching between work and master is required, a switching valve needs to be inserted into the test circuit that must not leak. Cosmo Instruments offers a dedicated switching valve based on our expertise in leak testing. This ideal valve prevents valve leaks and also prevents deformations.

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.

SMD crystal devices are becoming smaller and smaller. The LZ-3000 series is a leak test system developed to meet the high-speed processing needs of gross leak test on small electronic parts such as sealed SMD quartz crystal devices. We provide the ideal system for improving your production efficiency and product quality management system.

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.
