Easy Switching

The LS-R910’s large frame body developed with the basic specification of the LS-R900 offers a feature to switch between 2 test pressures (Inlet A and Inlet B). The combination of the 2 pressures (Inlet A and Inlet B) can be selected from the Grade Table. Up to two EP regulators can be set in the leak tester. This allows you to increase both productivity and efficiency at the cost of only one device.

Down Arrow

Measurement Screen
With the ability to change the language of the device from English to Japanese and Chinese, you'll never have to worry about misunderstanding certain functions and features ever again.
Inlet Selection Displays
This allows the user to select the two different inlets on the go with just a click of a button, making it easier to modify and view the required data when you need it.
Charge-Hold Display
The LS-910 makes your life easier by directly showing you if there are parts to be tested are pressurized or not. This function remains active regardless if the stop valve is open or closed.
