The new DELTACHECK leak-tightness measuring systems enable cost-effective and reliable differential pressure measurement through the use of specially developed and standardised modules:

  • Test rack
  • Control equipment and measurement data processing software
  • Measuring instrument


  • Overview
  • Features
  • Applications
  • Delivery Scope

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

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

  • Measurement technology: ISM
  • Pneumatics: Festo
  • Profile building system: Item
  • Control equipment: Siemens / Advantech / NI

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

  • Industry 4.0 ready
  • Parameter input and process visualization via 17 “touch screen
  • Test stand control by fanless industrial PC
  • Measurement data storage
  • Surveillance of all process-relevant parameters
  • Manual or automatic closure of the test stand
  • “Test object in position”-monitoring
  • Gross leak monitoring
  • Exchangeable plates for different test specimens (option)
  • Automatic test object clamping and adapter closure (option)
  • Operator protection by safety light curtain (SICK)
  • Quick-change systems with central coding connector (option)
