Positest HHD

  • 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 — Â±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

    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.
