The PosiTest HHD is a high voltage holiday detector used for detecting holidays, pinholes and other discontinuities using pulse DC technology. It offers a user-adjustable voltage range from 0.5 to 35kV for detecting holidays, pinholes and other discontinuities in coatings up to 780 mils (20 mm) thick. It is ideal for use with a wide range of rolling spring and flat wire brush electrodes. Alternatively, use existing electrodes with industry-standard adaptors.
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.
