Helium Leakage Measurement - Industry 4.0 ready.

The new HELICHECK leak-tightness measuring devices enable the economical and reliable measurement of helium-tightness by using specially developed and standardized modules:

  • Test stand
  • Control equipment and measurement data processing software
  • Vacuum equipment
  • Measuring instrument(s)

The customer-specific adaptation to the test object remains as the only special design and is manufactured by our in-house design and machining department.

The exclusive use of the following high-quality components significantly increases the availability of the testing machine:

  • Vacuum equipment: Pfeiffer Vacuum
  • Measuring instruments: Pfeiffer Vacuum
  • Pneumatics: Festo
  • Profile building system: Item
  • Control equipment: Siemens / Advantech / NI

This configuration consisting of standard modules and custom test specimen adaption allows us to deliver fast and at favourable prices.
