Stationary Inspection of Corrugated Hoses – ISOTEST® act Industry Solution

In the automotive industry, in the mechanical and industrial engineering sector as well as in the medical technology industry corrugated hoses are used as protection or for bundling of electrical or other wiring or as flexible connection to peripheral devices.


The in-plant holiday detector systems ISOTEST® act allow the safe and reliable porosity testing of thermoplastic corrugated hoses. A contact-free testing using ring electrodes and a simple grounding method by means of a tube mandrel allow an easy integration in your production process.

Our recommendation

In-plant Holiday Detector ISOTEST® act 8.0 / 35

  • test voltage 0.5 - 8.0 kV, 0.5 kV steps (ISOTEST® act 8.0)
    or 7.5 - 35 kV, 2.5 kV steps (ISOTEST® act 35)
  • high-voltage pulse technology
  • no static charging
  • testing of dirty, damp and even slightly conductive surfaces
  • up to 6 test channels – synchronisation of several devices (master / slave mode)
  • “Phantom-Grounding” – no direct grounding necessary
  • external switch-on / switch-off of the test voltage
  • adjustable sensitivity and filter functions
