Whether a component or a system is leak-tight depends on the application and its acceptable leak rate. Absolutely leaktight components and systems do not exist. A component is considered leak-tight if its leak rate remains below a value defined for that particular component. In order to provide a quantitative measure, the term “leak rate” with the symbol “qL” was introduced.

The LDS2010 is a modular helium leak detectors for universal integration into industrial leak testing systems. This leak detector was especially designed to speed up industrial leak test processes.

Building up a leak test bench was never easier. The Modul1000 is the world first leak detector that fulfills jobs which are normally done by a PLC. The detector itself provides all necessary valves for a vacuum leak test and controls the complete leak test process from charging the test object with helium until venting of the test chamber.

The mobile UL1000 with a rotary vane pump is an automated leak detector offering fast pumpdown and short response time for quick testing results in industrial systems.

The mobile UL1000 Fab with its dry vacuum system is an automatic leak detector offering fast pumpdown and short response time to meet the demanding requirements in semiconductor applications.

The mobile UL5000 is designed to meet the most critical and demanding semiconductor applications, providing fast pumpdown time and delivering fast response time.

INFICON Protec P3000 Helium Sniffer Leak Detector is specifically designed for full-time sniffing applications in demanding production environments.

The Ecotec E3000 leak detector brings new levels of productivity and reliability to the final testing of refrigerators, freezers, automotive air conditioners and similar products. It is specifically designed for demanding production environments. Numerous features make it easy and comfortable to use while making it more immune to careless operation and minimizing operator errors. It is also fast to make the best use of your available cycle time. Innovative design and robustness keep the cost of ownership down and ensure very high up-time.

The Ecotec E3000A multi-gas leak detector is the reliable and low-cost solution for testing cooling circuits in Airbus airplanes. Simpler and measurably faster than conventional leaktesting methods, the Ecotec E3000A does not require evacuation. It simply “sniffs” for refrigerant leaks while the system is in use, reducing downtime and waste. The Ecotec E3000A is recommended for use in the A340 (for more information see AMM chapter 25-34-00) and will also be recommended for the next-generation A380. It comes with a library of more than 100 detectable gases including all refrigerants and heat transfer fluids used in Airbus airplanes as well as many other commonly used gases.

The HLD5000 refrigerant leak detector uses an innovative technology to find leaks quickly and reliably with dramatically fewer false alarms.

In order to perform reliable quantitative measurements of leak rates, the used leak detection equipment must be calibrated by inlet of a known leakage flow delivered by a test leak.

Capillary leak with helium reservoir and manual valve. Leak rate range 10-7 mbar l/s.

Universal gas source for the fast insert in a variety of applications Helium capillary leak for vacuum and sniffing applications. Adjustable leak rate in the range between 10-4 to 10-6 mbar l/s. Besides helium, which is included in delivery, the TL4-6 is also usable with different kind of gases.

Manufacturers of helium leak testing systems require calibrated leaks of various sizes with individually adjusted leak rates for the purpose of setting up and calibrating their systems.

Helium sniffers in connection with the UL1000, UL5000 and the Modul1000 leak detectors are used for leak testing test samples in which a helium overpressure is present. Besides pinpointing the leaks, it is possible to determine the leak rate of the escaping helium.
