Leak Detection

MKS PICO® Helium leak detectors are the smallest and lightest mass-spectrometer-based leak detectors in the world. Weighing just under 17 pounds, PICO® sniffing-style and vacuum leak detectors set a new standard for portable leak detection. PICO® helium leak detectors are the most compact, lightweight and portable mass spectrometer-based Helium leak detection instruments available. They are fast, contamination-free leak detectors, with a design that incorporates patented mass spectrometry and vacuum technology. The small size and unique design of PICO® Portable Helium Leak Detectors significantly reduces start-up, response and clean-up time.

Helium is an excellent gas for leak checking, however, due to availability or manufacturing constraints it may be necessary to leak check using other gases. In this case, Residual Gas Analysis (RGA) is an excellent alternative as a vacuum system diagnostic tool.
