My mattress did not come with this particular tester, and I wanted to rule out any chance of a placebo effect. Placebo would have worked for me, but the tester is too easy to use, it is compact and the price was right. Review: Works - Worked great to test my sheets to see if they need replacing. I have mine plugged into the yard. The sheet snap and lines near the snap lit up but no lights on the majority of sheets. So I know it’s works, it’s just old. ## Features - Important Note: Only used for conductivity testing. The tester will light up if the test object is conductive, even if the grounding port is not connected. Be aware of this before purchase - 【Conductivity and Grounding Tester】The conductivity test pen can detect whether grounding products can conduct electricity and provide grounding. Place both probes on the product you wish to test (e.g. a grounding mat, sheet, pillowcase or socks) and if the material is conductive, the light will come on. Slide the tester over the surface of the grounding product to test for continuity - 【How It Works】When the two probes of the conductivity test pen are connected by conductive material, an electronic circuit is formed and the light will be on. So we can use it to test the grounding products if it can be grounded - 【Easy to Use】It takes only 1 second to know if the grounding product is conductive. The grounding product being tested does not need to be plugged into a grounded outlet. If it is not conductive, it cannot be grounded even when plugged into a grounded outlet - 【Button Cell Battery Included】The grounding tester comes with 3 LR41 batteries. The test pen is ready to use straight away. When the batteries are exhausted, simply remove the foot pad and top cap of the pen to replace them. - 【Attention to Safety】This test pen is not intended for use by children under the age of 8. It is only used to test the electrical conductivity of objects, and cannot be used as an electrical pen to touch live wires and equipment. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #17,185 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Ground Resistance Meters | | Customer Reviews | 4.2 out of 5 stars 315 Reviews | ## Images ![Conductivity Test Pen, Tester for Earthing, Continuity Tester for Grounding Mats, Sheets, Pads, Socks, Pillow Cases.

I have mine plugged into the yard. The sheet snap and lines near the snap lit up but no lights on the majority of sheets. So I know it’s works, it’s just old. ### ⭐ NOT GROUNDING SHEET TESTER *by D***. on February 9, 2026* This product is not a grounding sheet tester. it is a continuity tester amd the fact that this false advertizing is on here is horrible. This does NOT test if your grounding sheet is actually connected/grounded properly. Shame on you scanmers. ## Frequently Bought Together - Conductivity Test Pen, Grounding Tester, Continuity Tester for Grounding Mats, Sheets, Pads, Blankets, Pillow Cases.
