Product Brief
XHDQ703 Single-jaw Earth Resistance Tester is a versatile device for earth and loop resistance measurement, widely used in power, meteorology, oilfield, construction and industrial electrical equipment. It enables non-destructive testing of looped earthing systems without disconnecting down-leads or using auxiliary electrodes. Ideal for detecting undetectable earth faults and working in unapproachable scenarios for traditional tools, the XHDQ series clamp-on tester delivers the integrated resistance value of earth electrodes and their connecting leads.
