DeFelsko — PosiTest HHD C Kit High Voltage Holiday Detector
Continuous DC Output Holiday Detector for Coating Porosity & Discontinuity Inspection SKU: HHDCKITOverview
The DeFelsko PosiTest HHD C Kit is a high voltage holiday detector designed for detecting pinholes, voids, holidays, and other discontinuities in protective coatings. Featuring continuous DC output, this detector provides reliable inspection performance for coatings applied to conductive substrates such as steel, concrete with conductive backing, and pipelines.
Built for professional coating inspection workflows, the PosiTest HHD C helps verify coating integrity by applying high voltage across the coated surface and identifying defects where current passes through to the substrate. This makes it an essential tool for corrosion prevention, coating quality control, and asset protection programs.
Supplied as a complete kit, the PosiTest HHD C is ideal for field and shop inspections in oil & gas, pipeline, marine, infrastructure, and industrial maintenance applications where coating performance is critical.
