Super High Pressure Air Leak Tester LS-R740(SH)

LS-R740 (SH)

LS-R740SH is a differential pressure Air Leak Tester
realizing highly sensitive leak test under super high
pressure condition.
Up to 16MPa can be applied for the leak test.

Edge & Function

Easy-to-navigate and intuitive interface with simple menu configuration

Waveform display of test pressure and differential pressure

Influence of noise generated during the test on the workpiece can be compensated, reducing the test time

Three languages selectable. English, Chinese, Japanese

USB port for easy test data management

Closer placement of the sensor unit to the target capsule
