LS-R912
The large chassis of the LS-R912, developed from the basic specifications of the LS-R900, offers the function to switch between two test pressures (Input A and Input B). The combination of the two pressures (Input A and Input B) can be selected from the nominal values table. Up to two EP regulators can be configured on the leak tester. This allows you to increase both productivity and efficiency at the cost of a single device.
Measuring screen
With the ability to change the device language from English to Japanese and Chinese, you will never again have to worry about misunderstanding certain functions and features.
Input selection screens
This allows the user to instantly select the two different inputs with just a click of a button, making it easy to modify and display the necessary data when needed.
Load-holding screens
The LS-910 makes your life easier by directly indicating whether the parts to be tested are pressurized or not. This function remains active regardless of whether the shut-off valve is open or closed.
