Fukuda is a leader in the design and manufacturing of both standard and custom leak test machines. Our leak test machines have been applied in medical, automotive, defense, aerospace, and many other industries. Fukuda’s advanced technology and quality reputation has allowed the company to provide products with operating modes including pressure decay, vacuum decay, mass flow, differential flow, pressure charge, volume verification, occult testing, seal creep testing, helium leak, and other testing systems to customers.
Fukuda’s leak test systems are designed with end-users in mind. The machines are fast, clean, environmentally conscious, and sustainable. Leak test systems are manufactured with advanced designs, features, and test algorithms that provide reliable results for air leak testing, gas leak testing, and other testing where reliable equipment is necessary. Results of the leak test are straightforward, and the data easily available for further analysis. Leak detections are effective and efficient.
Air leak testers judge leaks by pressurizing the inside (or outside) of sealed work by air and measuring the pressure change. When the master shows no leak and work with leaks are pressurized, the pressure of the work with leak will decrease, generating pressure difference between the master and work. The leak is measured from this pressure difference. Generally, this differential pressure type air leak test is used for leak check. However, Fukuda provides a lineup of products using direct pressure type leak test or flow meter according to the leak rate in addition to differential type leak testers. Furthermore, air is used as the medium for tests with these testers in which running cost is lower and more environment-friendly.
