ISOTEST® portable Holiday Detectors / Porosity Detectors – High Voltage Inspection of Coatings

The non-destructive holiday detection of coatings with high voltage allows the detection of even smallest pinholes. Equipped with cutting-edge high voltage technology the ELMED ISOTEST® holiday detector is an indispensable assistant in passive corrosion protection. Efficient and reliable porosity testing with minimal material stress of the coating – this is the result of decades of experience as well as intensive and ongoing customer dialogue.

Non-conductive coatings and coverings on a conductive base, such as metal, can be high voltage tested non-destructively. Normal visual inspection can easily miss pores, cracks or other damage that are easily detected by high voltage impulses.

 

For damp, dirty and even only slightly conductive surfaces, ISOTEST® holiday detectors offer you the maximum test energy with the greatest possible safety – for both the tester and the test results. High voltage impulse technology coupled with patented automatic regulation keeps the test voltage stable, even in extreme circumstances. The microprocessor controlled sensitivity adapter guarantees a non-destructive test with the ideal test voltage.

ISOTEST® holiday detector cover various norms and standards – amongst others DIN EN 10288, DIN EN 10289, DIN EN 10290, DIN EN 10300, DIN EN 10310, DIN EN 10329, DIN 4681, DIN EN 14330, DIN EN 14879, DIN EN 15159-1, DIN 55670, DIN 30670, DIN 30672, DIN 30677-2, DIN 30678, DVGW G 462/I, W 400-2, GW 14, GW 15.

 

Our delivery programme includes portable holiday detectors as well as in-plant inspection systems for pipe mills, film / foil production and a wide range of further industrial applications.

Advantages of ISOTEST® High Voltage Holiday Detectors

  • reliable and efficient porosity testing thanks to cutting-edge technology and appropriate accessories for any application
  • testing of humid, dirty and even slightly conductive surfaces
  • reliable holiday detection of completely coated objects by means of phantom grounding (capacitive grounding)
  • the patented automatic regulation guarantees stable test voltages in any test situation
  • power reserve for demanding test situations
  • self-calibrating high voltage generation– automatic calibration within a few seconds every time the device is switched on
  • pipe diameters from DN 50 up to DN1600 can be tested in a single pass
  • up to 10 years warranty*

 

* with annual ISOTEST® service

Possible Applications of the ISOTEST® Holiday Detector

  • coated or enamelled tanks or reactors
  • rubber linings
  • films / foils
  • thermoplastic coatings
  • plastic welding joints
  • external pipe coatings
  • testing of internal pipe linings
  • valves, corrugated hoses and machine parts
  • inspection of inliners
  • leak detection of battery trays
  • roof inspection
  • holiday detection on busbars
  • and many more

 

Wherever there is a combination of conductive and non-conductive layer coatings, cracks and defects can be reliably detected.
