T-213H HANDHELD MICROOHM METER

The T-213H handheld Micro-ohm meter also known as transformer DC resistance tester, DC resistance fast tester and grounding continuity tester, adopts Microprocessor technology and four wire method for testing, which is safe, precise and reliable. It is mainly used to measure the resistance of transformer winding, winding resistance of transformer, conduction test of grounding down lead, conductor resistance of cable, switch, connector, contact resistance of relay, coil, motor, and connection electricity between metal components of equipment shell, lightning strip, ground beam, structure, cabinet, steel bar, water pipe, window, guardrail, radiator, assembly line and other objects Resistance test. It is widely used in telecommunication, electricity, meteorology, computer room, oil field, power distribution line, transmission line of iron tower, gas station, factory grounding grid, lightning rod, etc.
