Engineered for field and industrial use, the stick-type PosiTest HHD employs short, high-voltage pulses (10 µs, 30 Hz) to detect coating defects without sacrificing safety. Its lightweight ABS enclosure, long Li-ion battery life, audible/visual alarms, and strong ground reference cable make it suitable for rigorous conditions and protected surfaces.
DeFelsko PosiTest HHD Stick-Type High-Voltage Holiday Detector
Designed to meet global inspection standards, the PosiTest HHD Stick-Type combines wide voltage adjustability, integrated safety features (press-and-hold trigger, long ground cable), and user aids such as the international standards voltage calculator. Complete with hard-shell or Pelican™ case kits, it provides dependable performance with ease of use in tough environments.
Features
0.5 to 35 kV output; fine adjustment in 10 V steps (0.5-1 kV) then 100 V steps above 1 kV.
Built-in voltmeter that displays actual electrode voltage and maintains ±5% accuracy under load.
Both audible and visible (strobe light) alarms alert operator immediately when a holiday is detected.
Press-and-hold trigger to prevent accidental activation; long 7.6 m ground cable; sealed design per IEC 61010-1 for creep prevention.
Rugged ABS housing; multiple kit options (Pelican Storm case or hard-shell), lightweight with ergonomic grips; long battery life under typical loads.
