ASM 390 AND ASM 392

Mobile leak detectors optimized for rapid pump down
and short response times on large test objects.

Superior performance,
fast testing

The ASM 390 and ASM 392 are the perfect leak detection
solutions adapted to the semiconductor and display industries
as well as to other demanding applications where rapid
pump down and high sensitivity is key. Both models are fully
Semi S2 compliant.
These leak detectors are fitted with a dry frictionless backing
pump and a powerful high vacuum pump, making them theideal tools for leak testing of various components in clean
environments. Equipped with an additional turbopump, theASM 392 will speed up your leak detection process to reducethe downtime of your production equipment.

2Robust, accurate
and reliable

The ASM 390 and ASM 392 were developed to provide
full confidence in leak testing regardless of the operator’s
knowledge. They deliver premium performances and accurate
results in a minimal time, making them highly efficient in thefield.

Ergonomic andhighly maneuverable

ASM 390 and ASM 392 share the same platform and are
uniquely ergonomic with a convenient size and height, asecondary handle in the front, a fully rotatable, removabledisplay, an inlet in the front for easy connection to test ports
and unrivaled maneuverability for access to all testing areas,even in tight spaces.

Smart and user-friendly

Thanks to a wide, clear color touch display panel, an inte­
grated toolbox with modular compartments and storage
space for vacuum bellows, you will be amazed how easy leakdetection can be when you have all necessary accessories atthe point of use.
