RONKONKOMA, N.Y., March 10, 2013 — A portable hydrogen mass spectrometer leak detector released by Vacuum Instrument Corp. tests the integrity of components, systems and parts using hydrogen leak detection techniques.

Designed for use with 5% H2 and N2 gas mixtures, the MD-490S H2 provides an alternative to companies with high helium costs and associated supply issues. The unit delivers a response time of <0.5 s, sensitivity to the smallest detectable leak rate of 5 × 10–7 Atm-cc/s H2 (atmospheric sniffer mode), with a leak range of 10–3 to ~10–7 Atm-cc/s direct reading of H2 leak rate (compensated for atmospheric sampling), tuned for mass 2.

The device also features hydrogen background suppression, leak rate ranging, built-in calibrated gas leak, fully interactive system diagnostics with multilingual displays and front-panel key lockout. Options include a remote display and vibrating probe.

The detector is suitable for aerospace, medical, nuclear, automotive and vacuum applications as well as others that require a high level of leak-detection sensitivity.
