MD-490S DUAL GAS LEAK TESTER

PORTABLE HELIUM/HYDROGEN SNIFFER MODEL

MD-490S Dual Gas is the most advanced sniffing Helium/Hydrogen leak detector designed specifically for industrial environments. The MD-490S Dual Gas utilizes VIC’s own industrial-grade mass spectrometer to achieve the highest sensitivity, fastest response-time, and smallest footprint.

With a touch of a button, this dual gas unit can detect either Helium or Hydrogen tracer gases, while using a single built-in dual purpose calibrated gas leak.

It also meets the stringent requirements for robustness, reliability and ease of maintenance that are essential in any industrial environment..
