Review: Excellent conductivity pen - This pen works well to let you know that your mat is conducting as you would like for it to work. It is very easy, simply touch the double prongs directly to the mat and the top of the pen will light up. You may have to remove a cover off the double prong but after using the pen it is easy to slide the cover over the prong to put it away for the next time.
Review: They make your body feel - I love my grounding sheets. They are one of the best investments in the pen I have made lately thank you desertcart.

## 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.
