Ronkonkoma, N.Y., February 26 -- Vacuum Instrument Corp., a world leader in the leak
detection industry, today introduced their first portable hydrogen mass spectrometer leak
detectors for testing the integrity of components, systems, and parts using hydrogen leak
Designed for use with 5% H2 in N2 gas mixture, the MD-490S H2 provides an alternative 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 H2 (atmospheric sniffer mode), with a leak rate range of 10-3~10-7 Atm-cc/second
direct reading of H2 leak rate (compensated for atmospheric sampling), tuned for Mass 2.
Some key features include: 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 H2 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.
