|Portable Dry Leak Detector
|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:
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.)
environment operation (aerospace industry, instrumentation,
medical and pharmaceutical industry, food industry,
and user-friendly interface
The ASM 122 D is a self-contained unit
integrated to a cart with a minimal footprint and exceptional
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
●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.

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.
