Portable Dry Leak Detector
ASM 122D
The innovative concept of the ASM 122 D makes it the ideal portable dry leak detector to meet any maintenance needs for clean applications.
It is recommended for a wide range of applications:
Leak testing vacuum systems in the semiconductor industry
Leak testing components (valves, filters, ...)
Maintenance of system chambers in the research and developments
laboratories (beam lines, vacuum systems, etc.)
Clean environment operation (aerospace industry, instrumentation, medical and pharmaceutical industry, food industry, ...)

EASY TO MOVE POWERFUL EASY TO USE
The ASM 122 D is a self-contained unit integrated to a cart with a minimal footprint and exceptional manoeuvrability.

The ASM 122 D offers unmatched performance in all test modes:
> Sniffing mode: The new auto-zero function ("floating-zero" method) delivers the ability to measure leaks as small as 1.107 mbar.l/s.
> Inboard testing mode:

The 4 1/s (240 1/min.) helium pumping speed and the compression ratio of its high vacuum pumps provide ultra-fast response and recovery time.
Sensitivity of 5.10'2 mbar.l/s.

A very comprehensive display control panel, with direct access to integrated functions, makes this unit easy to operate for any end-user.
A modern and user-friendly interface which meets every user profile

Operation
Rugged remote control: very easy to use and easy to hold. The helium signal is displayed in two different ways : dynamic green/red bargraph to highlight the fast evolution of the signal and digital
display to get a high resolution and a direct readout.
Variable pitch audio alarm proportional to the helium signal amplitude for easy location of leaks in complex systems. 
Settings and maintenance
Comprehensive display panel:
indicates the user mode, settings,
maintenance information
(preventive and corrective
maintenance), all of which is
password-protected.
Easy-to-use and effective integrated functions

Auto-calibration
Auto-calibration with built-in temperature compensated calibrated leak.
Auto-calibration during the start-up sequence and the ability to activate periodic auto-calibration.
All pertinent information related to the auto-calibration process and its settings.

Signal correction
Automatic correction processed by
the detector through an external
calibration.
Possibility to manually adjust the
correction factor (for direct readout
of the helium signal regardless of
the leak rate unit).

Auto-zero 
The auto-zero function is an advanced feature which allows the operator to conveniently improve the sensitivity of the detector when the helium signal
measurement becomes more difficult due to a high background level.
The auto-zero function is even more helpful in sniffing mode, for suppressing the background signal due to the residual helium in the air (5 PPM) enhancing the sensitivity up to 1.107 mbar.l/s.
The principle of the function is to subtract the background'in order to focus on the helium signal. The new method developed by Alcatel is based on a specific algorithm ("floating zero" method) which eliminates the display of erroneous results and guarantee to detect any size leaks.

All these functions are directly accessible by depressing one single key switch.
