How to choose Air Leak Tester

For standard leak test

Leak test to measure the leakage coming
out of tested parts by pressurizing inside
the part with a test pressure between
5 kPa and 1.5 MPa.
LS-R902 LS-R700 LS-1881 LS-1866

Choosing Tester By The Specifications Of The Part To Be Tested

Test pressure is rather high between 1.5 MPa to 4.9 MPa LS-R902
Testing by high pressure above 5MPa LS-R740(SH)
Parts that deform by pressurization Contact us for details.
Sealed and deformable component Package leak testers Contact us for details.
Sealed products which hardly deform LS-R740(SH) LZ-1550
Part temperature is hotter or colder than the ambient temperature such cases as right after welding or washing process. LS-902(T)
Temperature mpensation Model
Part volume is quite small LS-R902(Micro-volume pneumatic circuit) LS-R700(Micro-volume pneumatic circuit)
Leak specification is large.  Test for large leaks AF-R220
Want to test both discharge flow and leak. LS-1866(FD)
