Low Resistance Tester 0.001mOhm-300.0KOhm

         Digital DC low resistance meter, also known as micro-ohmmeter, ohmmeter, equipotential tester, uses microprocessor technology, four-wire method test, safe, precise and reliable. Mainly used to measure the cable resistance, contact resistance of switches, connectors, relays, resistances of coils, motors, transformer windings, and equipment enclosures, lightning protection belts, ground beams, structures, cabinets, steel bars, water pipes, windows, guardrails, heat dissipation Device, assembly line, and other objects between the metal components of the connection resistance test. Widely used in telecommunications, electric power, meteorology, machine rooms, oil fields, power distribution lines, transmission lines of iron towers, gas stations, factory grounding networks, lightning rods, etc.
