1-Second Conductivity Verification (No Outlet Needed!) Instantly detect electrical conductivity on ANY grounding product (mats, sheets, wristbands, etc.) by placing both probes on the surface – LED lights up immediately if conductive. Crucially, this works WITHOUT needing the product plugged into a grounded outlet!
Key Safety Insight: What the Light REALLY Means The LED activates SOLELY from material conductivity – it will light up on conductive surfaces even if the product isn't connected to ground. This confirms material function, but remember: A lit light ≠ proof of grounding. True grounding requires both conductivity + earth connection.
How It Works & Grounding Validation When probes bridge conductive material, they complete the circuit and light the LED. Critical use: If the light doesn't activate, your product cannot conduct electricity – meaning it will fail at grounding even when plugged in.
Ready to Use + Hassle-Free Battery Access Includes 3x pre-installed LR41 batteries – start testing right out of the box! When depleted, simply unscrew the caps to replace (standard button cells, no tools required).
Effortless & Reliable Quality Control Slide probes across surfaces to check continuity (no gaps!). Ideal for manufacturers, retailers, or home users to verify product quality before use. Compact and durable for lifetime testing.
