MD-490S – DUAL GAS
HELIUM/HYDROGEN LEAK DETECTOR
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..
