100A 200A Loop Contact Resistance Micro-Ohm Tester
The SXHL Loop Contact Resistance Micro-Ohm Tester is engineered for precise measurement of contact resistance in high and low voltage switchgear main contacts, as well as DC resistance in high and low voltage cable lines. Featuring constant current output options of 100A, 200A, or 500A with a maximum output voltage of 10V, this tester delivers 2-3 times higher voltage than conventional models, enabling the use of test leads with smaller cross-sectional areas.
