An innovative, truck-mounted Static Ground Verification System -- the Earth-Rite® MGV from Newson Gale -- enhances safety during transfer of flammable or combustible materials. Earth-Rite® MGV derives its power source from the vehicle battery and uses certified, intrinsically safe monitoring techniques to verify not only a good bond to a valid ground point, but more importantly confirmation that the ground point to which it is attached represents a satisfactorily low resistance to true earth. The unit is simple to install and operate and provides confirmation of positive bonding and grounding to the operator by way of a bright flashing green LED cluster. It also provides a pair of change over contacts (DPDT) for connection to additional safety devices (strobe lights, audible alarms) or for interlocking with the vacuum pump or control valve. The “business end” of the system employs a heavy duty stainless steel clamp with universal clamping jaw which can be connected to flat or rounded surfaces, including directly to ground rods.
