MD-490S Dual Gas Leak Detector

MD-490S Dual Gas 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.

FEATURES

MD-490S DG FEATURES & BENEFITS

• One Button Switch between helium and hydrogen tracer gases.
• Fastest Response Time in the Industry (less than 0.5 seconds)
• Fully Automatic Calibration sequence with built-in dual gas (helium and hydrogen mix) NIST calibrated gas leak which prompts the operator to insert probe into the built-in leak and adjusts the machine’s leak rate reading to match the leak value. Designed for use with 5% H2 in N2 gas mixture, or Helium (user selectable
• The Vibra-Leak™ Probe option with background suppression button provides tactile feedback when leak rate exceeds the reject set point; Ideally suited for noisy environments where audio alarms cannot be heard or where leak detectors are in close proximity; Vibra-Leak™ Probe solves background tracer gas problems during the test; Optional remote display.
• Tracer Gas Background Suppression with a push of a button; the MD-490S eliminates the tracer gas background.
• Most Sensitive Sniffer Available with 10-8 sensing capabilities through enhanced tracer gas collector design and signal processing.
• Fully Interactive System Diagnostics with multilingual displays include critical parameters such as run times, operating voltages/currents and pressures.
• Graphical and Numerical Displays of leak rate values.
• Sealed Membrane Keypad for long life in harsh environments.
• Dry (oil-free) Vacuum Pumping minimizes maintenance and potential oil-contamination problems.
• Probe Blockage Alarm ensures proper system performance.
• Front Panel Key Lock-Out prevents unauthorized use.
• High Output Adjustable Audio Alarm up to 110 dB.
• Less than 3 minutes total start-up time.
• Five year warranty on major components.
