PosiTest® HHD
The 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
