Air Leak Tester
for sealed products

PRODUCT INFORMATION

LS-R740WL

LS-R740WL tests the airtightness of sealed products.
The part to be tested is placed in a capsule andpressurized to measure the pressure change causedby leak flowing into the part.

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

Easy volume compensation when the tested partand the reference part have a volume difference.

Closer placement of sensor section to thetarget capsule
