fukuda leak tester manual

This leak test method allows the finest leak detection out of all Fukuda leak testers. The system detects ultra fine leaks to the 10 -15 level using helium leak testing. We are able to build highly-reliable leak testers for various items, including seal jigs and components around the testers, using our knowhow that we have accumulated over the years. We will cater to a wide range of needs, from low to high pressure and from low flow rate to high flow rate, by proposing the most appropriate testing method (for air, hydrogen, helium) that suit the customer requirements. Please feel free to contact us. We are also able to issue a traceability certificate for this unit. 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. 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. 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. 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.

Refer to the following in regard to the handling of personal information. Please note that there is a charge involved for acquiring operation manuals. Please contact us if you require operation manuals. When the master with no leak and work with leak 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 a direct pressure type leak test or a 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 low and is environment friendly.Master-less air leak testing is possible. Master-less air leak testing is possible. It is a Separated Type. Measurement time can be reduced by using the turbo function. You can combine it with a separate display unit to be installed into the automated equipment. Sensitivity check and test component volume measurement can be carried out. We are also able to issue a traceability certificate for this unit. It is a highly versatile device used in a wide range of fields. It is recommended for test components with a varied volume, where measurement becomes unstable if an air leak tester is used. In addition, this leak tester is able to specify the location of the leak. An industrial gas mixture (non-flammable gas: ISO10156:2010), containing 5% hydrogen and 95% nitrogen, is used as the tracer gas. We have a lineup of detectors and system products. A helium leak test system works by using helium gas as a tracer gas and by detecting the bombed helium that is found from the leak site.

Furthermore, air is used as the medium for tests with these testers in which running cost is lower and more environment-friendly. All rights reserved. If there are any problems such as incorrect specifications, missing accessory parts or damages with the delivered items, please contact your FUKUDA agent. Please compare the model numbers described below with the number indicated on the tester’s nameplate. Thus, it requires different handling instructions from other standard precision equipment. Vibrations or earthquakes may cause the tester to fall and cause injury to operators. Please keep this in mind to help obtain accurate and reliable leak testing. PRIMARY PRESSURE REGULATOR Adjust to: (approx.) This implies that even if there is the same degree of leak, depending on the internal volume of the tested works, the pressure reduction rate will also vary.
