Grounding Outlet Tester for Earthing Products

This compact tester verifies that a standard US wall receptacle is correctly wired before you connect grounding sheets, mats or other earthing accessories. It is designed for EMF-sensitive households and anyone who wants confirmation that their outlet provides a safe ground path. The tool plugs directly into a 120 V socket and requires no batteries or configuration.

UL-Certified Build with Clear Light Patterns

The unit carries UL certification and uses a simple three-light arrangement to identify open ground, open neutral, open hot, hot/ground reverse, hot/neutral reverse and correct wiring at a glance. Its corded-electric design means there are no internal cells to replace, and the 3.25 by 1.45 by 1 inch housing fits easily in a tool bag or travel kit for checks on rental properties or job sites.

Passive Operation with Zero Power Draw

Because the tester draws only the tiny current needed to illuminate its indicators, it adds no measurable load to the circuit and produces no fan noise or heat during use. You simply insert it into the receptacle, read the pattern, and remove it, making routine verification quick and unobtrusive for daily grounding-product users.
