HIGH VOLTAGE HDD

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

  • The PosiTest HHD uses pulsed DC technology to detect flaws. Instead of a continuous high-voltage output, the PosiTest HHD emits a precise pulse of high-voltage 30 times per second. This technology is much easier to ground, and safer, reducing the possibility of the exterior of the object becoming charged. The advanced circuitry is capable of maintaining a precise voltage output over the full range of 0.5-35 K-V in a single instrument. To alter the set voltage, simply choose the voltage selection menu option, and use the plus and minus buttons to adjust.
