Holiday / Porosity Detector
The holiday detector is also
known as a porosity detector,
jeep testers or jeeper.
Porosity or holiday detectors are employed
in the non-destructive detection and location of pinholes, holidays,
spots or thin
points in protective coatings applied for corrosion protection
over metal and concrete (conductive) surfaces. Detectors are suitable
for production pipeline coating operations, tankwork and structures.
Compact DC Holiday Detector
The Compact DC Holiday Detector is small and lightweight with a
clip-on battery pack and features digital display of applied
test current, fully adjustable voltage and sensitivity controls.
It can be used in most applications including pipelines, steel
and tankwork. Commonly known as holiday detectors, spark testers
or jeepers. Complies with the requirements of AS3894.1-2002.
Compliant. More info...
Compact Pulse Holiday Detector
Holiday Detector with fully adjustable, regulated 'pulsed' output
up to 20kV, 40kV or 60kV. All pulse porosity detector models
can be used for porosity
of carbon impregnated coatings such as carbonated rubber, thick
coatings such as rubber linings and on ‘plastic’/fibreglass
type coatings likely to become electrostatically charged.
The Pulse 20kV
& 40kV models are ideal for use in moist conditions, on wet
and contaminated coating surfaces. The Pulse 60kV model is the
portable battery operated model on the market capable of generating
voltages from 10,000 to 60,000 volts. More info...
Superior porosity holiday detector. Portable
single hand held unit, designed with the inspector in mind. Unit
only 460g. Two models: up to 10kV; or up to 20kV using the extended
use power pack. More info...
Compact Wet Sponge Tester
Uses the wet sponge method to detect pinholes in coatings. Models
available: 9, 67,5 and 90 volt Selectable and 67.5 volt fixed. Large
sponge head & telescopic handle which extends to 1.2m (47").
We highly recommend high voltage holiday and porosity testing in
lieu of wet sponge testing when working with coatings over 150 µm,
or coatings in corrosive environments. Complies with the requirements
of AS3894.2-2002 (Wet Sponge Testing). CE Compliant. More info...
