    The DeFelsko Replacement Sponges for Holiday Detectors are consumable accessories designed for low-voltage wet sponge inspections used to detect pinholes, pores, cracks and other discontinuities in non-conductive coatings.

    During testing, the sponge is moistened and installed on a compatible detector. As it is moved across the coating, it provides uniform contact with the surface and allows the instrument to detect conductive paths through defects in the protective coating system.

    Supplied in a package of 3 units, these sponges are suitable for replacement during inspection routines, helping maintain reliable wet sponge discontinuity testing.

  • Function Details

    FUNCTION DETAILS

    Wet Sponge Inspection
    Designed for use with low-voltage holiday detectors that employ the wet sponge inspection method.

    Pinhole Detection
    Helps identify pinholes, pores, cracks and other defects that may provide an electrical path to the conductive substrate.

    Good Liquid Absorption
    The sponge structure retains the solution used during testing, helping maintain contact with the coated surface.

    Uniform Surface Contact
    Helps the electrode maintain consistent contact while moving across the coating during inspection.

    Replacement Consumable
    Suitable for periodic replacement of sponges used with compatible detectors, particularly when the existing sponge becomes worn or unsuitable for reliable testing.

    Package of 3
    Provides a practical supply for inspection teams that require replacement sponges during coating inspection activities.
