Ramping Production – MD-490DG


MD-490S Helium and MD-490S Dual-Gas Sniffers

Press Release


September 2017 – Vacuum Instruments Corporation, LLC announces it is ramping production of non-helium tracer gas Leak Detectors.  In response to increased demand from it’s customer base, the company has significantly stepped up production of it’s Leak Detectors which use Hydrogen and Argon in lieu of Helium.  These gases are used in multiple industries by VIC’s customers.  The MD-490DG has long been recognized as a mainstay in leak detection, utilized by automotive, utility and plastics manufacturers and the company is the only LD provider to offer Argon Leak Detection capability, heavily used in Aerospace and Defense.  As a result of customer demand and VIC LLC well regarded history of applications expertise, production of these non-helium Leak Detectors is expected to increase five fold over the next 12 months.  Additionally, the company offers other gas management solutions such as helium recovery systems and gas mixers/boosters which are increasingly in demand in light of the periodic fluctuations in the Helium market.


Service and Support Programs



Vacuum Instruments Corporation, LLC offers a variety of support programs designed to help reduce downtime and minimize operating costs.

For 24 Hour Emergency Service call: 1-800-221-2440

Individual service contracts are available for scheduled maintenance of leak detection equipment—at your facility or ours. Each plan is individually designed to meet the requirements of your application, your level of equipment usage, and your overall in-house maintenance and operator status.

Field service by factory-trained VIC engineers provide unparalleled process application expertise directly to your production line. VIC’s service centers in the USA, Mexico and Europe permit rapid response—typically within 24 hours of request.

Training is available for all VIC leak detection products with a variety of standard programs on your premises or ours, or we can customize a training program specific to your individual requirements.

Repair and Overhaul Services VIC offers comprehensive factory service for our leak detectors, an excellent value for revitalizing equipment and returning it to production-worthy status. VIC does not charge any evaluation fee for complete leak detectors: customers are provided with a written quotation outlining the repair service required; repairs are conducted only upon customer authorization. Lead time is typically 1 to 2 weeks after authorization.

Exchange Service VIC provides factory refurbished, repaired or recalibrated assemblies that are ready for immediate installation. Most exchange items are available within 24-48 hours, to minimize customer-downtime as well as their inventory of spare parts.

Upgrade Packages bring new life to your leak detection system

Recalibration Services include a certificate with traceability to N.I.S.T. on all of our manufactured leaks and all non-VIC manufactured leak standards as well. Exchanges are available on all SC7 gas leaks with lead times of one-to-two weeks.

Recalibration Services

cal-scQuality Control and Calibration Laboratory

We offer a full recalibration service for calibrated gas leaks manufactured by VIC and other companies from our new 3000 sq-ft calibration laboratory located in our New York headquarters.  Services include recalibrating and recharging with replacement of the precision element if breakage or clogging occurs, along with full N.I.S.T. recertification.

All gas leaks are individually recalibrated using the accumulation method in accordance with American Vacuum Society Standard 2.2-1968. This primary method approved by N.I.S.T. ensures the highest degree of accuracy, and unlike the commonly used secondary transfer method, VIC leak calibrations are not dependent upon electronic instrumentation.

Certificates of N.I.S.T. traceability are provided with each leak standard documenting the accuracy, and calibration parameters on all of our manufactured leaks and all non-VIC manufactured leak standards as well.  Exchanges are available on all certain model gas leaks with lead times of one-to-two weeks.

MS-50GT Console Leak Detectors Sport Touch-Screen GUI Display

MS-50GT_RVacuum Instruments Corp., LLC a world leader in the leak detection industry introduces a series of console Helium and Argon mass spectrometer leak detectors with LCD touch-screen GUIs.  The leak detectors are used for testing the integrity of semiconductors, electronics, aerospace, medical products, used in research and development as well as a host of other applications which require mass spectrometry leak detection.

All models include a 10” capacitive touch-screen flat panel LCD display mounted on an articulating bracket that allows the operator to use his/her finger to navigate through a vast array of menus, settings and options.  The Touch-Screen GUI allows for greater system control and monitoring during system start-up and operation.

Displays include system status, accept/reject indications, system health, set-up, calibration and other diagnostic functions.  The GUI allows the operator to quickly calibrate the system with the MS-50GT’s built-in leak standard and view a leak rate.  System Diagnostic Mode enables one to monitor several operating parameters and includes an interactive system valve and operation schematic.  With its 50 test recipes, the MS-50GT is designed to take the guess work out of testing and automate your process.

The MS-50GT Series leak detectors are offered in Helium and Argon tracer gas versions.  Additional versions include, Dual test ports, Ultra Fast Test (UFT) and Dry oil free Helium or Argon gas models.

MD-490S – The Real Sniffer

The MD-490S is the highest sensitivity sniffer. That's why we call it “The Real Sniffer”VIC Leak Detection / Vacuum Instruments Corporation, LLC

The MD-490S is the highest sensitivity sniffer with a response time less than 0.5 seconds and the ability to zero-out background, this is the most aggressive portable leak detector in the industry, with advanced features designed specifically for industrial use.

MD-490S Features and Benefits – for complete specifications and catalogs click here!

  • 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.
  • Fully Automatic Calibration sequence with built-in 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.
  • 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 110dB.


The Smartest Leak Test Combo

Smart ChargeIII unit compliments the MD-490S by providing trouble-free tracer gas handling.  It prevents tracer gas background contamination in the test area that can lead to ambiguous test results or false leakers.
