Pfeiffer - Model ASM 340 -Leak Detector

The ASM 340 leak detectors are characterized by their powerful pumping systemand are available with an oil-lubricated or dry backing pump. Easy operation, an ultra-fast response time and short sensor recovery are among the top features of these compact multipurpose units.

The dependable leak detectors can be used for both qualitative localization of leaks as well as quantitative global testing (assessing the leakage rate over entire objects) or local testing (targeting individual leak points). The ASM 340 are the only leak detectors in their class offering qualitative leak detection from a pressure of 100 hPa (mbar). This means that even if the leak detector cannot reach the test pressure because of a leak in the system, this leak can still be determined and located.

No training is required to operate the ASM 340 units. Simply use the large, high-resolution touch screen on the control panel to configure the leak test. The resulting data can be recorded and stored in the internal memory as a bitmap or text file, ready to be transferred on a USB stick via a dedicated USB port. In addition, ASM 340 leak detectors can be equipped with acomprehensive selection of communication options, from I/O to fieldbus.

ASM 340 with oil-lubricated rotary vane vacuum pumpsThese compact leak detectors are equipped with the largest rotary vane backing pumps in the appropriate size class, allowing extremely fast cycle times.

ASM 340 D with dry diaphragm vacuum pumpsThe dry ASM 340 D units are equipped with diaphragm backing pumps. They are used in applications where very clean test conditions are required, such as in the semiconductor industry.

ASM 340 I without backing pumpThis specific unit offers maximum flexibility and is typically used for integration into leak detection systems.
