PosiTest HHD

High Voltage Holiday Detector

Detects holidays, porosity, pinholes, leaks, and other discontinuities in coatings, linings, and membranes using pulse or continuous DC.

Conforms to ASTM D4787/D5162/D6747/D7953/G62, ISO 29601, NACE SP0188/SP0274/SP0490, AS3894.1

Features

Available as a stick-type with pulsed DC or a compact wand style with continuous DC
Lightweight, ergonomic design provides comfortable all-day use, reducing operator fatigue
Regulated pulse or continuous DC voltage output that won’t change under load— ±5% voltage accuracy
Voltage calculator feature—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
