Pfeiffer Vacuum

Multipurpose

Multipurpose leak detectors by Pfeiffer Vacuum combine high performance and easy operation with the reliability which you have come to expect.

The best in class compact multipurpose leak detectors - now with 2 years warranty
The leak detectors in our ASM 340 series guarantee top performance in vacuum or sniffing leak detection for various applications, from maintenance to applications in small production environments. These dependable leak detectors can be used both for qualitative localization of leaks as well as quantitative global or local testing. They are the only leak detectors in their class offering qualitative leak detection starting at 100 hPa before reaching the inlet test pressure.
The ASM 340 is characterized by its powerful pumping system and available in conventional or dry versions. Easy operation, ultra fast response time and short recovery time are among the outstanding features of these compact multipurpose units. The ASM 340 is the perfect solution for everyday testing even in severe test conditions.
