Newson Gale OhmGuard Hose Continuity Tester

The OhmGuard® Hose Continuity Tester, manufactured by Newson Gale, is designed to ensure that strings of assembled hoses have good electrical continuity with a grounded truck, which ensures that electrostatic charges cannot accumulate on metal components. The OhmGuard® operates on the principle of a “PASS or FAIL” test procedure. To operate the device, the driver will first ground the truck and then assemble the required number of hose sections to the truck. The driver will then connect the OhmGuard® clamp to the free coupling or nozzle of the last hose (see illustration). If the electrical resistance through the string of hoses to the grounded truck is “good”, a green LED mounted in the OhmGuard® clamp will pulse continuously informing the driver that the hoses are bonded to the truck and are safe to use. If there is a break in continuity, the LED will not pulse and the driver may carry out a quick visual inspection of the hoses to ensure parts like wire helixes have not suffered broken connections with components like end couplings. The driver may also elect to test each hose individually.
