There are two different types of Porosity Detection. The one you select is based on the total thickness of the coating/lining system. Low voltage or wet sponge holiday detectors are used on coatings/linings that are less than 500 microns thick. High voltage holiday detectors or spark testers are used on coatings/linings greater than 500 microns, and in some cases down to 250 microns.
Elcometer 270 Pinhole Detector
We offer Elcometer 270 Pinhole Detector.Variable voltage settings at 9, 67.5, & 90V DC. Complete with belt fastener,probe and lead, and groundwire.
266 High Voltage Holiday Detector
Easily detects pinholes, flaws and thin spots in coatings. Provides safer, easier and more reliable testing than previously possible. Interchangeable Probe Handles allow voltages from 5kv, 15kv & 30kv.
Elcometer Model 106
Testing adhesion or bond strength of the coating to the substrate is imperative for successful coating procedures. Model 106 adhesion tester can be used to test the pull-off strength of a coating or coating system. It is a mechanical adhesion tester, which uses a calibrated compression spring to produce a perpendicular force on pull stub.
Wet Film Thickness
Wet Film Thickness give the inspector a quick, low cost method of checking the thickness of freshly applied coatings.
