Air Leak Tester
for micro volume parts

PRODUCT INFORMATION

LS-R740
SSLS-R740SS performs highly sensitive leak test on
micro volume parts. The part to be tested is set on
a fixture, and inside of the part is pressurized tomeasure the pressure change generated by leak.

FeaturesEasy-to-navigate and intuitive interface withsimple menu configuration

User selectable multi-language capability:
English, Japanese and Chinese

Waveform Display of Test pressure andDifferential pressure

USB Port for easy test data management

Influence of noise generated in the test on thepart can be compensated, reducing test time.
