Pfeiffer Vacuum

MiniTest 300 is a mobile leak detector weighing 11 pounds, making it the ideal companion for on-site service calls. Helium is detected with a quartz window sensor instead of a mass spectrometer. It operates at a working pressure of up to 200 mbar without requiring additional pressure reduction. Large facilities and systems can be tested for leakages by just one person. MiniTest requires no internal pumping system.
