Three Voltage Wet Sponge Pin Hole Detector
Part NO: WSPD-1006
Descriptions:
The Tester is also knowns as wet sponge testers, Thin Film Holiday Detector,low voltage holiday detectors, low voltage porosity detectors or pin hole detectors,has received wide acceptance in the corrosion control and industrial painting industry as a device for locating bare spots (or holidays,cracks etc) in the thin protective films which are sprayed or brushed on metal or concrete surfaces. This pinhole detector is non-destructive with low voltage of 9V,67.5V,90V DC output. The inspection electrode consists of a 168×68×28mm cellulose sponge which, when dampened with water, is moved over the coated surface. When the electrode passes a void or bare spot, a small current flows and actuates an audible signal in the instrument. The damp sponge provides an electrically conductive film that contacts the surface being inspected and insures good inspection even in corners and around irregular shapes where holidays are most likely to occur.
Applications
Use the wet sponge method to detect pinholes in thin coatings.
