Features Operation is very simple, usually only use two keys(leak detection key and Deflation key) Imports multi-port molecular pump Double filament automatically switch Automatic zero Automatic calibration Automatic range switching Matched with a cart Technical parameters Can detect the smallest leak rate 5×10-12Pa.·m3/s Detection range 10-3 ~10-2 Pa.·m3/s Maximum air inlet pressure 1000Pa Response time <1s Sniffing mode 1×10-8 Pa.·m3/s Ambient temperature 5°~35°C Relative Humidity <80% Supply voltage 220v±10%,50Hz Maximum operating current 6A Test port specifications DN25 ISO-KF Dimensions W900×D560×H650 Weight 72kg Suction gun Standard 2.5m(According to customer requirements) Applications SFJ-211 helium leak detectors will be widely used in semiconductor process equipment maintenance, industrial gas detection and installation of systems, components in the assembly before the leak rate test and requires high pumping speed, high sensitivity and clean testing conditions of applications.
SFJ-211 Helium mass spectrometer leak detector is designed by taken example by foreign advanced leak detection technology and depends on our company’s mass spectrum production experience. Key components are imported, SFJ-211 with stable and reliable performance. Not only with high sensitivity,but also convenient operati
on. double filament can automatic switch,automatic zero, automatic calibration and automatic switch the range, reached the international advanced level.
