A static grounding verification system for applications requiring dual-channel grounding monitoring, designed to check two grounding lines simultaneously, confirm true grounding and improve site safety control.
Earthing Pro DU is designed for industrial applications where two grounding lines need to be monitored at the same time.
It not only checks whether the grounding clamps are connected, but also verifies whether each grounding path is truly effective, helping reduce safety risks caused by static buildup.
It is suitable for loading and transfer operations requiring dual-point grounding confirmation, dual-equipment grounding monitoring or a higher level of safety control.
In some loading and transfer operations, a single grounding channel is not enough to meet actual safety requirements.
When two pieces of equipment, two grounding points or two grounding loops must both be confirmed, a standard single-channel grounding system may not provide sufficient monitoring.
Earthing Pro DU checks two grounding lines at the same time, helping confirm that both grounding conditions are safe before operation begins and improving site control.
Connect the two grounding clamps to the target equipment or grounding points.
The system checks both connection statuses and verifies whether both grounding loops are effective.
Only when grounding conditions are safe can the operation continue.
If either grounding line becomes unsafe, the system triggers alarm or interlock action.
