Two different types of pressure ranges can be tested using just one tester!

The newly available LS-R910 has touch panel operation, quality control with USB, multilingual support, etc. continuing with the convenience and easy of use of the LS-R900, and allowing for the testing of two different types of pressure ranges with just one tester.

The LS-R910 is a new leak tester that meets a variety of demands

Edge & Function



For tests where different ranges of test pressure are used with a single product
pic_ls-r910_2

Test 1 location Test pressure 2 ranges

pic_ls-r910_3

(Attention) Keep in mind that you cannot run test 1 and 2 simultaneously.

For example, this kind of product

For tests where 2 different ranges of test pressure are used for multiple test locations in a single product(A valve is needed for switching to a separate testing location.)

The combination of test pressure ranges of 2 circuits (Port-A/Port-B) can be chosen from the support table below.
Of the combinations of various pressure ranges, choose two types that meet your demands from the table below. 

Fine tuning of the test pressure is now simple.
lsr-910-02

Pressure is applied to the workpiece.
If you push the button above, it will be shifted to the following button for easy fine tuning of the pressure.
