Refined design an easy to operate. Cosmo Instruments confidently presents this new generation of air leak tester.

This truly new generation air tester combines the experience and know-how that Cosmo Instruments has nurtured over many years, with new functions and the newest technology.

Adopted touch panel color LED.
The icon display on the menu screen is simple and intuitive, and the reportedly difficult operation of the instrument has been revamped.
Anyone can use it right away.
The measurement screen is available in 6 different types for different situations, including a simple display and a detailed display, and a display in which you can observe measured waveforms.
The LS-R900 is a new air leak tester that meets a variety of demands.

Edge & Function



Simple to operate with icons.

The menu screen is easily displayed with an icon.
The Home icon can move directly to the measurement screen, and the (i) icon in the upper right displays all sort of information.

Can switch between 6 kinds of measurement screen
ls-r900-edge-img07

The measurement screen is available in 6 different types for different applications/situations, including a simple display and a detailed display.
Also, the display items can be customized.

Each type of settings screen
ls-r900-edge-img08

During setup, a large numeric keypad appears, and all types of settings can be adjusted using the simple screen display.

A complete help screen and help display
ls-r900-edge-img09

In the help screen, complete explanations of computational tools and peripheral devices are available.

Waveform monitor function for test pressure/DP (leak volume)
ls-r900-edge-img10

Displays the test pressure and DP waveforms from measurement start to detection completion.
The ideal time for applying pressure and attempting detection can be found.

Phoenix Contact product is used for input/output connector
r900_phoenix

Phoenix Contact product was adopted for the connector of the input/output interface.
The connector is very reliable, and the wiring work can be done with a flat-head screwdriver, so that the work efficiency increases.

Automatic setup function

Several setting are necessary for the leak test.
This function provides initial settings for measurement time when first implementing the leak test.

Easy data collection with USB port

Measurement data is automatically saved to USB memory.
Other settings information can also be backed up with USB memory.

Waveform Pneumatic Circuit Diagnosis

Checks for anomalies in the air circuit with workpiece at each operation.
(Attention) Effectiveness varies based on operating conditions, and there are cases when it cannot be used.

Function for switching between display of multiple languages

Supports Japanese, English, Chinese, Korean, German, Spanish, and Portuguese.
Overseas expansion is simple.
