Capable and Versatile

  LS-R740(ZL)


The LS-R740(ZL) is ideal for testing waterproof components of finished products that require IP protection rating. The part to be tested is placed in a capsule and pressurized to measure the pressure change caused by leakage flowing into the part.

Intuitive and easy-to-navigate interface with simple menu configuration.

Test pressure and differential pressure waveform display.

The influence of the noise generated during the test on the workpiece can be compensated, reducing the test time.

Three selectable languages: English, Chinese, Japanese.

USB port for easy management of test data.

Closest location of the sensor unit to the target capsule.
