DeFelsko — PosiTest® HHD High Voltage Holiday Detector
High Voltage Coating Discontinuity Detector for Protective Coatings SKU: HHDKITOverview
The DeFelsko PosiTest® HHD is a high voltage holiday detector designed for locating pinholes, voids, holidays, and other discontinuities in protective coating systems. Built for professional coating inspection workflows, this instrument helps verify coating integrity on conductive substrates before service or during maintenance inspection.
With an output voltage range of 0.5–35 kV, the PosiTest® HHD provides adjustable high voltage inspection capability for a wide range of coating thicknesses and applications. Based on NACE SP0274-2011 recommendations, it supports coating thickness inspection up to 20 mm / 780 mils, making it suitable for heavy-duty protective linings and industrial coating systems.
Portable, reliable, and field-ready, the PosiTest® HHD is ideal for pipeline, tank, vessel, marine, infrastructure, and industrial coating inspection applications where corrosion protection and coating quality are critical.
