Micro Ohm Meter Ohmmeter with USB Data Upload 0.001mΩ～300.0KΩ Resolution 1uΩ

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.
