DeFelsko PosiTest LPD Low Voltage Pinhole Detector
Want to confidently catch coating defects before they cost you? The PosiTest LPD gives you multiple voltage options, a rugged waterproof body, and accessories to adapt to many surfaces. Bright LEDs, a handy earbud, and a safety-ground check (GroundSense™) make inspecting feel safer. Lightweight and built to last even in tough job-site conditions
Features
Four selectable voltages (9V, 67.5V, 67.5V, 90V ±5%) to conform to various inspection standards and coating types.
When a coating defect (pinholes) is detected, it signals both visually and via sound. GroundSense ensures the instrument is properly grounded for reliable detection.
Sealed enclosure, dustproof, splash-proof. Designed for harsh field environments.
