Pfeiffer Vacuum introduces the new ASM 340 leak detector

 September, 2014   pfeiffer-vacuum

  • Reliable leak detection for quality assurance
  • Short cycle time and high throughput
  • High performance and sensitivity with easy operation
  • Helium and Hydrogen leak detection for global (chamber) testing or sniffing applications


The new ASM 340 is a high-performance (5xE-12 mbar l/s sensitivity) and robust leak detector for production testing. The ASM 340 is suitable for leak testing a wide range of applications (components and assemblies) in the Automotive, RAC, Aerospace, Medical Device and General Engineering industries. The compact leak detector is suitable for both global vacuum chamber testing and sniffing applications

The ASM 340 with a powerful vacuum roughing pump (11cfm) may negate the need for additional vacuum systems for chamber testing. The detector readily plugs into any test system and with intuitive programming for both test parameters and the configurable I/O interface - the unit can be set up, ready to run, very quickly. Leak testing can start at 100 mbar so no time is wasted pumping to a lower level if not strictly necessary. The detector is extremely sensitive in sniffing mode to both helium and hydrogen with detection capabilities down to 5xE-9 mbar l/s (<0.001oz/yr refrigerant equivalent)

A large selection of configurable interfaces enables easy integration of the detector into production lines and automatic test systems. The removable graphical user interface and easy menu structure makes set up fast and easy. Data can be saved to the integrated SD card and then downloaded to an external device for further analysis. The wireless remote control enables operation from a distance of up to 300 ft . Thanks to the robust design and the minimal maintenance required, service costs are also very low.

With its extensive accessories, the ASM 340 can be adapted to specific applications. A special transport cart also enables mobile use of the device. Existing accessories for leak detectors in the ASM series are also compatible with the new device.

To complement the market introduction of the ASM 340 Pfeiffer Vacuum presents the Leak Detection Compendium. This handbook offers combined leak testing and leak detection expertise.
