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 the grounding product is not conductive, it cannot be grounded even if it is plugged into the grounded outlet
Grounding Mat Test
Grounding Sheets Test
Grounding Wristband Test
Water Test
Distilled Water ( The light is not bright)
If the object being detected is pure and free of minerals, then it does not have conductivity, and this closed loop will not be electrified, so it will not light up
Mineral Water ( The light is bright)
If this water contains minerals, then it is conductive, and its closed loop will be electrified, forming an electrical circuit, and the light will turn on
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 (The higher the conductivity, the brighter the light)
