MiniTest 300 Portable Leak Detector

ASSLAR, Germany, July 11, 2012 — With the MiniTest 300, Pfeiffer Vacuum GmbH introduces a vacuum leak detector with quartz window technology. The helium is not detected as it usually is with a mass spectrometer, but, instead, with a quartz window sensor. Weighing only 11 lb, the system is suited for mobile leak detection. In combination with the wireless remote control operation of the RC 500 WL, large facilities and systems can be tested for leakages by a single operator.

The MiniTest 300 operates at a working pressure of up to 200 mbar, without requiring additional pressure reduction. In comparison with a traditional leak detector with a mass spectrometer as a helium sensor (working pressure ~20 mbar), this is a significant advantage with respect to cost and materials. The maintenance costs are lower than for traditional leak detectors because the detector is a helium partial pressure measuring device that requires no internal pumping system.

The detection limit of 5 × 10−7 mbar enables its use for leak detection in industrial applications such as coating and vacuum systems and vacuum furnaces.

The device is equipped with two leak detection functions. An existing leak is located as quickly as possible when in search mode, the qualitative leak detection mode. If, in addition to the localization, the size of the leak also is required, the measuring mode — the quantitative leak detection mode — must be used. All measurement data can be saved in the device’s remote-control system and stored on a USB stick for further use.
