PRODUCT INFORMATION

AIR LEAK TESTERLS-R912

Switching of two test pressures●LS-R912, designed based on LS-R902, features a function
to switch between two test pressure circuits.

●Select the combination of two test pressures (Inlet A and
Inlet B) according to your needs.

• Set the higher pressure for Inlet A.
• Two Pressure Sensors for the same
higher pressure will be installed.

• When selecting "VR" or "V" for Inlet
B, only dry works can be used.

• For a combination not listed above,
RFQ is required.
