Hydrogen Leak Detector

Portable Helium/Hydrogen Sniffing Leak Detector.

The portable helium tracer gas sniff only MD-490S is considered the Leak Detection “Work Horse” by manufacturing companies worldwide is now available in two tracer gases.

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 Dual Gas Features and Benefits

  • One Button Switch between helium and hydrogen tracer gases.
  • 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.
  • 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.
  • 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 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.

Smart Charge III
A fully automatic, custom configurable evacuation and gas backfill system with built-in gross leak test that may be used to pre-charge products under test with gas for leak detection or for any gas charging application that requires evacuation and subsequent pressurization of a test product.
Model No. Smart Charge III, Part No. 926-326
GM-BS
A microprocessor-based system designed to blend two gas components, typically helium and air.  These systems provide a cost effective alternative to 100% tracer gas.
Model No. GM-BS, Part No. 925-090
GB-AS
Gas booster systems produce high-pressure process gas supplies from lower pressure sources, typically boosting a shop air source. Base units provide up to 600 psig pressure output. Options include higher pressure outputs and process gas drying capabilities. Can be configured for single gas or dual gas boosting.
Model No. GB-AS
HRS
Introducing a solution to lower the cost associated with tracer gas consumption While industries strive to meet increasing demands to offer higher quality products at lower prices, the need to efficiently recycle process gas becomes apparent. Helium Recovery features a group of high efficiency gas recycling systems that significantly reduce tracer operating costs. The Helium Recovery Systems offered consists of ASME coded pressure tanks, a set of compressor(s), gas analyzer, microprocessor controls and all necessary valving, gas regulation and piping.
Model No. HRS
Calibrated Gas Leaks

OM
The OM Series gas calibrator leaks utilize a precision tapered glass capillary as the leak element. Gases pass through a single orifice, with the leak rate dependent upon size and gas pressure. To prevent clogging of the fine orifice, a unique particle trap is located between the capillary tube and outlet fitting.
Model No. OM
