Grounding Continuity Tester for Grounded Products, Mats, Sheets, Pads, Wrist Bands, Blankets, Pillow Case. Universal. 15 Foot Cord Included. Use to Test Effectiveness of Earth Connected Products.

When testing my grounding mat with this I discover neither ground plug in one receptacle works!!!

This little tester takes the guess work out of the grounding product. Plug it into a grounding plug & press. If the light blinks, the tester is working. Then place it on your connected grounding mat & press the button again. If the mat is grounded, the light will come on&stay on till removing the tester off the grounding mat or pillow case or whatever grounding source you are using.

Muy fácil para medir , yo había comprado otros y eran muy difíciles de usar. Muy buena compra

The instructions leave a lot to be desired.

It works

Does indicate when it’s working.

I was excited to get the tester. However, it seems to be a button that flash a green light. Even when I unplugged it from the socket and pressed the button, the light still came on. I’m not sure it is testing anything.

Works and arrived quickly.

Im so glad I got a tester! It is super helpful for letting me know if outlets are grounded properly & if my grounding items are still in working order. I had a grounding pillow case that was no longer functional. So, that was good to know! But all my other grounding items are in good working order!

I have several grounding pads and a sheet and have gifted many as they really have helped take away the pain in my knees from sprains in the past. But i always wonder if some of them are working or not. This tester was so easy to work and gave me confidence they are really grounded. Thanks for making such a great product available!
