ASTM D6747

The PosiTector HHD High Voltage Holiday Detector detects holidays, porosity, pinholes, leaks, and other discontinuities in coatings, linings, and membranes 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
