Allen Industries service technicians and engineers offer professional Vanguard SGT-200 safety ground tester repair and calibration service. In fact, we offer repair and calibration services for many models from many manufacturers of test equipment. The Vanguard SGT-200 Safety Ground Tester is a 200A DC micro-ohmmeter designed specifically to measure the resistance of protective in-service grounding and jumper cable assemblies. The Vanguard SGT-200 can measure the resistance of the grounding cables, clamps, and ferrules. The measured resistance values can be compared against the calculated values (using the ASTM 2249-03 standard) and a Pass/Fail result can be printed along with the measured resistance values. Once your Vanguard SGT-200 safety ground tester is received, our technicians will evaluate your instrument and will send you a formal estimate. Vanguard’s services are performed only AFTER approval. Standard and rush Vanguard SGT-200 safety ground tester repair and calibration services are also available.
