Description

PosiTest LPD operates by moving a moist sponge electrode over a coated surface; when a pinhole exposes the conductive substrate beneath, current flows and triggers a visual/audible alert. It offers four voltage settings (9V, 67.5V, another 67.5V, 90V ±5%), sensitivity settings, and comes both as Basic and Complete kits. Accessories include roller or flat sponges, extension rods, long ground wires, and more.
