Portable Helium/Hydrogen Sniffing 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. This unit is available in hydrogen only or helium and hydrogen models.
