Ronkonkoma, NY, February 26, 2013 — Vacuum Instrument Corp., a world leader in the leak detection industry, today introduced their first portable, switchable helium/hydrogen mass spectrometer leak detectors for testing the integrity of components, systems, and parts using helium or hydrogen leak detection techniques.
Designed for use with Helium or 5% H2 in N2 gas mixture, the MD-490S Dual Gas provides an option to companies who want to eliminate the high cost of Helium and associated supply issues. The unit boasts a response time less than 0.5 seconds, sensitivity to smallest detectable leak rate of 5x10-7 Atm-cc/second He/H2 (atmospheric sniffer mode), with a leak rate range of 10-3~10-7 Atm-cc/second direct reading of He/H2 leak rate (compensated for atmospheric sampling), tuned for Mass 2.
Some key features include: Helium/Hydrogen background suppression, less than 3 minutes total start-up time, leak rate ranging, automatic zero, fully interactive system diagnostics with multilingual displays, front panel key lock-out, standard probe and built-in calibrated gas leak. Options include a remote display and exclusive vibrating probe.
The MD-490S Dual Gas leak detector allows for greater access to superior system intelligence with a push of a button to accurately locate and measure leaks in a wide range of applications. Typical applications/industries include: aerospace, medical, automotive, appliance, vacuum, nuclear, as well as a host of others requiring a high level of leak detection sensitivity.
