Introduction SFJ-231 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. 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 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
