DC Low Resistance Tester Micro Ohmmeter with 0.01mΩ~30.00KΩ Accuracy ±0.1%FS




Introduction:
   
       It is mainly used to measure the wire resistance of cables, the contact resistance of switches, connectors, relays, the 

resistance of coils,  motors, transformer windings, as well as the resistance test of the linkage between the metal components 

of the equipment shells,  lightning straps, ground beams, constructions, cabinets, reinforcement bars, water pipes, windows, 

guardrails, radiators, assembly lines  and other objects.
