Leak Detector ASM 390 - Pfeiffer Vacuum

High performance - Mobile

The ASM 390 is optimized for fast and accurate leak testing in all measurement ranges. It is the perfect combination of high dry pumping performance, sensitivity and mobility in the smallest footprint.
  • 35 m3/h (21 cfm) roughing capacity using frictionless and oil free ACP pump
  • 10 l/s helium pumping speed for a faster response time
  • 20 hPa crossover pressure for a rapid entry into measurement mode and additionnal massive mode for large leaks
  • Color touch panel display with full 360° viewing offering excellent visibility
  • Intuitive menu with password protection to prevent from unintended use
  • Available with interface board for automation through an external system (PC or PLC)
The ASM 392 provides unrivalled performances with high sensitivity and accuracy. Sharing the same platform as the ASM 390 and equipped with an additionnal turbopump, the ASM 392 will speed up your leak detection process, without any compromize on footprint and maneuverability.

Accessories for ASM 390 - ASM 392

The mobile high-performance leak detectors by Pfeiffer Vacuum are optimized for rapid pump down and short response times for large test objects.
The ASM 390 and ASM 392 are the perfect leak detection solutions adapted to the semiconductor and display industries as well as other demanding applications where rapid pump down and high sensitivity is key. Both units are fully Semi S2 compliant.
These leak detectors are fitted with a dry frictionless backing pump and a powerful high vacuum pump, making them the ideal tools for leak testing of various components in clean environments. Equipped with an additional turbopump, the ASM 392 will speed up your leak detection process to reduce downtime of your production equipment.

Ergonomic and highly maneuverable
ASM 390 and ASM 392 share the same platform and are uniquely ergonomic with a convenient size and height, a secondary handle in the front, a fully rotatable, removable display, 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 integrated toolbox with modular compartments and storage space for vacuum bellows, you will be amazed how easy leak detection can be when you have all necessary accessories at the point of use.
