Leak detection with air | pvcp (2024)

Leading air leak testing solutions for your leak test challenges

Whether it is industrial items, automotive parts, or pharmaceutical products: Our Micro-Flow air leak detectors offer high sensitivity as well as resolution accuracy and enable you to leak test with short cycle times and temperature stability.

Our leak detectors with the innovative Micro-Flow technology are unique in the industry. The Micro-Flow technology as well as Mass Extraction, as a special form of the Micro-Flow technology, bring several benefits especially in comparison to other air leak testing technologies. The main advantages thereby are the speed of test and the low susceptibility against environmental changes. Furthermore, it has higher sensitivity and accuracy. Both methods are non destructive and give a quantitative test result. Daily calibration is not required. Pfeiffer Vacuum offers compact, user-friendly and highly sensitive solutions for leak testing with air.

The Mass Extraction technique is a special way of using the Micro-flow sensor. The basic principle is based on a rarefied gas flow approach. In order to achieve a higher sensitivity, the test is performed under vacuum. With this approach a sensitivity of up to 6.7 · 10-7 mbar · l/s can be realized. This approach is particularly applicable for sealed packages, e.g. pharmaceutical CCI testing.

E-PDQ (EQ and MQ)

Compact design for Micro-Flow or Mass Extraction

Repeatability, speed, and amazing sensitivity, all in a compact design, are the most important purchase criteria for air leak testers in the sub 10−4 mbar · l/s class. In addition, the accuracy of the tester must be optimized in the flow range of the leak specification. The E-PDQ meets these requirements perfectly. It is fast, repeatable, has a high throughput, and is a perfect fit for leak testing consumer electronics and small medical products.

Easy system integration

The E-PDQ is designed for the quick production leak testing of small components and ensures that products meet their leak tightness requirements. Its compact design makes the E-PDQ perfectly suitable for system integration. It is available as EQ version for pressure applications and as MQ version for vacuum applications.

Cost-effective leak testing

The E-PDQ typically is used in applications in which the required cycle rate is very high. It is also utilized in scenarios where multi-channel integrated systems, as well as high levels of measurement sensitivity and accuracy, are crucial.
