PosiTest HHD High voltage Holiday Detector



PosiTest HHD Literature
PosiTest HHD Manual


  • Easy-to-use with bright, color LCD
  • Ready to measure—comes with everything needed for testing
  • Audibly and visibly alerts when flaws/holidays are detected
  • Lightweight, ergonomic design provides comfortable all-day use, reducing fatigue
  • Voltage calculator feature—choose one of 11 international standards, and input the coating thickness to automatically calculate the required test voltage


  • Rugged, environmentally sealed ABS plastic enclosure
  • Weatherproof, dustproof, and shockproof
  • Included hard shell case with custom foam inserts for superior protection
  • Two year warranty


  • Built-in certified voltmeter (crest meter, jeep meter) displays and regulates the voltage at the electrode
  • Long Form Certificate of Calibration included with each instrument
  • Conforms to national and international standards including ISO, ASTM, and NACE


  • Strobe light and loud audible alarms emitted when a holiday is detected. Audio alarm mode can be adjusted for differing environments.
  • Removable Smart lithium-ion battery with built-in charge state indicator


  • A wide range of rolling spring electrodes and wire brushes are available. Custom sizes available upon request.
  • Optional handheld wand accessory coverts the detector into a wand configuration ideal for testing hard-to-reach areas (suitable for voltages
    < 15 kV)
  • Industry-standard connectors and adaptors for compatibility with nearly all existing electrodes
  • User adjustable voltage range from
    0.5 – 35 kV


  • Press and hold Safety Trigger helps prevent accidental high voltage generation
  • 7.6 m (25′) ground (earth) cable with locking connector and spring clamp
  • Shock proof/creep proof—internally sealed to minimize creep distance to high voltage components. Designed in accordance with IEC 61010-1.
