High Voltage Holiday Detector

PosiTest® HHD

High voltage Holiday Detector

Detects holidays, pinholes and other discontinuities using pulse DC
  • 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

Description

 

PosiTest® HHD 

High voltage Holiday Detector

Features


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

Versatile

  • 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

Durable

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

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.

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
