Holiday Detector Wet Sponge
These units are also known as wet sponge testers low voltage holiday detectors low voltage porosity detectors or pin hole detectors.
Holiday detector wet sponge. During the test as the inspection electrode moves over the coated surface moisture from the wet sponge penetrates any discontinuities in the coating and makes a conductive path to the substrate. Selectable 9 67 5 or 90v thin film porosity testing. When the sponge moves over a coating flaw liquid penetrates to the substrate and completes an electrical circuit setting off the alarm.
The elcometer 270 range utilises the wet sponge technique and has been designed to set a new standard for wet sponge pinhole detectors a high quality low voltage detector with similar accessories to a high voltage spark tester. Manufactured in australia. Wet sponge pin hole detector.
Model is available in 9 67 5 or 90 volt selectable. A wet sponge holiday detector is a device that uses a wet sponge to perform a holiday spark test for the purpose of detecting discontinuities or holidays in a non conductive coating over a conductive material. Caltech engineering services india offers full range of holiday detectors for engineering construction and maintenance of paints and coatings we also manufacture and export wet sponge holiday test equipment also known as wet sponge pinhole detector pd 990.
0 to 20 mils 0 to 500 µm test voltage. This holiday detector uses the low voltage wet sponge method to detect pinholes holidays in coatings. A wet cellulose sponge is attached to the inspection electrode of a holiday detector low voltage wet sponge type instrument.
The new spy model 670 operates on a single 9 volt alkaline battery. Complies with the requirements of as3894 1 2002 wet sponge testing. The elcometer 266 holiday detector can be used to test porosity on coatings up to 7 mm 275 mils thick and is ideal for inspecting.
Pcwi wet sponge pinhole detector. When testing for flaws in coatings under 20 mils thickness it is recommended to use a wet sponge porosity detector. Unit output voltage is 67 5 volts dc.
