PosiTest® HHD

The High Voltage Holiday Detector detects holidays, pinholes and other discontinuities using pulse DC
PosiTest HHD
  • Lightweight, ergonomic design provides comfortable all-day use, reducing operator fatigue
  • Regulated pulse DC voltage output that won’t change under load — ±5% voltage accuracy
  • Voltage calculator feature — choose one of 11 international standards, and input the coating thickness to automatically calculate the required test voltage
  • Extensive electrode options — choose from a wide range of rolling spring and flat wire brush electrodes or use electrodes from other manufacturers with optional adaptors — custom sizes available upon request
  • Long Form Certificate of Calibration included with each instrument

Conforms to ASTM D4787/D5162/G62, ISO 29601, NACE SP0188/SP0274/SP0490, AS3894.1

Simple

  • Easy-to-use with bright, multicolor 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

Durable

Accurate

  • 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

Safe

  • 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.

Powerful

  • 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 provides power for up to 40 hours of continuous measurement
