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.

Test pressure is rather high between 1.5 MPa to 4.9 MPa	LS-R902
Parts that deform by pressurization	Contact us for details.
Sealed and deformable component	Package leak testers Contact us for details.
Part volume is quite small	LS-R902(Micro-volume pneumatic circuit) LS-R700(Micro-volume pneumatic circuit)
Want to test both discharge flow and leak.	LS-1866(FD)

Test log storage Feature Want to store test logs in USB memory.	LS-R902 LS-R700
