Description
Product Overview
The Merisky Conductivity Grounding Tester Pen is a compact, lightweight device designed to confirm the electrical conductivity of grounding products. Measuring just 5 x 0.8 x 0.73 inches and weighing only 0.71 ounces, it fits easily in a pocket or tool kit. The pen includes three LR41 button cells, so it is ready for immediate use. When the two probes touch a conductive material, an internal circuit completes and a bright LED illuminates, indicating a successful grounding path. This simple visual cue lets users quickly assess grounding mats, sheets, or other accessories without connecting to a live outlet.

Usage
Ideal for electricians, DIY enthusiasts, and health‑wellness practitioners, the tester works in any environment where grounding safety matters. Place both probes on the surface of a grounding mat, sheet, or pad; if the LED lights, the item conducts electricity and can be safely used. The pen requires no external power source, making it perfect for on‑site inspections, home setups, or travel. It is also useful in laboratories for quick verification of conductive materials.
