## Description

Condutivity Testing Pen, Tester for Earthing, Continuity Tester for Grounding Mats, Sheets, Pads, Blankets, Pillow Cases. Use to Test Effectiveness of Earth Connected Products. 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. Conductivity is the basic function of grounding products, and if it cannot conduct electricity, it cannot be grounded.

Review: Thank you. The pen worked very well. Not at the beginning,, but with persistence it started to work. Disappointing results with my grounding mat, though. I have not felt any effects after using it for several weeks.
Review: I live in UK. I bought this pen to check my grounding fitted sheet it works really well and easy to use. It gave me reassurance that it is still working well

## Features

- Important Note: The test pen will light up if the test material is conductive, even if the grounded socket is not connected. It is used to test electrical conductivity
- 【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 wristband) 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.

## Questions & Answers

**Q: What does grounding product do?**
A: The grounding products can connect your body to the earth, transfer electrons and then balance your positive and negative charges, anti-static, reduce fatigue and anxiety, improve sleep wellness and health etc.

**Q: Is it safe to use grounding product?**
A: Yes, it is. The grounding sheet connect with the ground socket and then connect to the earth, so it is completely safe.

**Q: What are the common grounding products？**
A: There are many grounding products available, such as grounding mats, grounding sheets, grounding socks, grounding bracelets, pillowcases, blankets, etc.

**Q: How do you know if the grounding product is working/on when you are using it?**
A: We can measure whether the surface of the product and the grounding wire is conductive with a continuity tester or a conductivity test pen. If it is conductive, you can enjoy the benefits of grounding.

### ⭐⭐⭐⭐⭐ Review
*by J***R on 24 October 2024*

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.
