Leak testing devices are used by our customers for quality assurance. Regular calibration is essential to ensure correct measuring results.

What’s more, when you use the ZEDcore measuring module, calibration can be performed without needing to send the entire leak testing device.

Initial evaluation & advice

The ZELTWANGER leak testing service always analyzes your needs and conditions on site as the first step.

During an initial evaluation, highly specialized application developers determine the correct testing parameters, conduct measuring feasibility analyses, and determine which test method would be viable and cost-effective. This is how we verify the achievable test reliability.

Our decades of experience from our own application developments, feasibility studies, and development projects that we have implemented with customers are the best foundation for establishing optimal integration planning for your production processes. To achieve this, we rely on individual device and software adaptations.

Training & workshops

Because complex knowledge and diverse experience are required in the field of leak testing, we offer our customers comprehensive and individual training for their employees.

We adapt our user-related training courses to focus on different aspects:

  • System operators
  • Maintenance technicians
  • Planners and developers
  • Leak testing seminar: Theory and practice

Other customer-specific training is available on request. Please get in touch if you are interested.
