304 Stainless Steel Wall Mounted Static Grounding Alarm JDB-2

A wall-mounted static grounding alarm in a 304 stainless steel enclosure, built for tank truck loading racks, drum filling points and solvent transfer areas. The unit monitors the grounding loop continuously; when resistance rises above the set threshold or the clamp is pulled off, the LED and piezo buzzer alert the operator before product is moved.
