LS-R740 (SS)

LS-R740 (SS)

Air Leak Tester for Micro Volume Parts LS-R740(SS)

Performs the highly sensitive leak test on micro volume parts.The parts to be tested is set on a fixture, and inside of the parts ispressurized to measure the pressure change generated by leak.

Edge & Function

Easy-to-navigate and intuitive interface with simple menu configuration
Waveform display of Test pressure and Differential pressure
Influence of noise genarated in the test on the part can be compensated, reducing test time
User selectable multi-language capability: English, Japanese and Chinese
USB port for easy test data management
Closer placement fo sensor section to the target capsule
