The Varian VS MD301 Portable Helium Mass Spectrometer Leak Detector combines the simplicity of two-button operation with advanced expert system intelligence. The VS MD301 has a programmable testing sequence and automated start-up function that makes the testing process convenient and efficient. The VS MD301 has a minimum detectable leak at 1000 ppm ambient helium at 5 x 10-12 atm cc/sec: 5 x 10-12 mbar l/s: 5 x 10-13 Pa m3/sec helium.

The state-of-the-art spectrometer and vacuum system offer exceptional capability, enabling various test methods for diverse applications. The VS MD301 Helium Leak Detector features high test port pressure for finding large leaks while having a 5 x 10-12 MDL sensitivity.

The Varian VS MD301 Helium Leak Detector's multiple system configurations allow broad testing flexibility. Operators can choose from primary pump or system mounting options, depending on application requirements and the testing environments. The VS MD301's sturdy and robust design makes it possible to operate under challenging testing constraints and in multiple locations. Common applications for the VS MD301 include industrial process tools, power generation, high energy physics, semiconductor production, and more. In addition, the VS MD301 meets the standard for CE, UL & CSA, assuring global acceptance.
