In this video, learn about how the PosiTest HHD High voltage Holiday Detector uses pulse DC technology to detect holidays, pinholes, and other discontinuities in a coating system.

PosiTest HHD High voltage Holiday Detector features:
• 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

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