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.
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)
- Vibra-Leak™ Probe 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.
- Sensitivity: Smallest detectable helium leak rate 5x10-7 Atm-cc/second helium (atmospheric sniffer mode). Tuned for Mass 2.
- Response Time: Approximately 0.5 seconds. Leak Rate Range: 10-3~10-7 Atm-cc/second direct reading of helium leak rate (compensated for atmospheric sampling).
- Startup Time: Less than 3 minutes; one-button automatic operation.
- Console: Microprocessor-based electronics incorporating 40-character alphanumeric prompting display; fully automatic operation including startup, shutdown, leak rate ranging, automatic zero, and diagnostics including operating and runtime parameters; contains 40 segment leak rate indicator and operator function buttons.
Miniaturized 90° deflection, fixed magnet design; all stainless steel construction; NW-40 flange for high vacuum connection; utilizes two non-burnout thoria coated iridium filaments.
- Pumps: 1.5 cfm mechanical rotary vane fore pump and 70-liter/second air-cooled molecular drag pump.
- Inlet System: Interstage design incorporating integral mass separator high flow atmospheric inlet; standard sniffer probe hose length 10-feet; other lengths available.
- Calibrated Leak: 150cc high pressure cylinder with low volume stainless steel leak element traceable to N.I.S.T. with calibration certificate supplied; easily removable for recalibration.
- Pressure Measurement: Probe blocked sensor (10-3 Torr); turbopump speed characteristics for high vacuum (10-6 Torr).
