Pfeiffer new high-performance helium mass spectrometry leak detector ASM 340 with a choice of oil or dry backing pumps. This helium mass spectrometry leak detector is a new upgrade of Pfeiffer HLT 560 550 570 Adixen ASM 142, the inlet pressure reaches 100 hPa can detect leaks, is a leak detector with relatively low starting pressure requirements on the market, and the whole machine is guaranteed to be imported from Europe. The helium mass spectrometry leak detector ASM 340 is suitable for industrial, analytical research, coating markets, etc. This helium mass spectrometry leak detector is rugged, resistant to atmospheric and seismic performance, effectively reducing the risk of operating errors. Leak detection rate that can be repeated for years. The compact design of the helium mass spectrometry leak detector ASM 340 is suitable for tandem production and continuous operation. The ASM 340 D (backing pump with oil-free dry pump) is launched simultaneously with the oil-free helium mass spectrometry leak detector  

Standard leak hole, suitable for helium mass spectrometry vacuum leak detector, channel type open, positive pressure and negative pressure, leakage rate support customization, leakage rate range: 1x10-3Pam3/s ~ 5x10-10Pam3/s,
