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-R900
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-R900
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
