Klein Tools ET140 Pinless Moisture Meter is a professional measuring device developed for non-destructive moisture detection in construction, maintenance, renovation, water leak inspection, and field assessment applications. With pinless measurement technology, it detects relative moisture levels in materials such as drywall, masonry, hardwood, and softwood without puncturing, marking, or damaging the surface. Using a material capacitance-based measurement principle, the device helps identify hidden moisture up to 3/4 inch / 19 mm deep. Its bright reverse-contrast display and 9-LED bar graph make moisture levels easy to read. Audible alerts, visual indication, and auto power-off features provide practical use in the field, while 0.1% display resolution and ±4% accuracy support reliable measurement performance. Supplied with a 2 m drop-protected compact ABS plastic housing, 9V battery, and instruction manual, Klein Tools ET140 is a portable, reliable, and easy-to-use moisture measurement solution for plumbers, maintenance technicians, construction professionals, inspectors, and water damage assessment teams.
