ES3070 Handheld DC Resistance Tester 10A Transformer Resistance Tester DC Resistance Fast Tester Ground Continuity Tester

Description
ES3070 handheld DC resistance tester, also known as transformer DC resistance tester, DC resistance fast tester, ground continuity tester, adopts microprocessor technology, four-wire method for testing, safe, precise and reliable. It is mainly used to measure the resistance of transformer windings, transformer winding resistance, grounding down conductor continuity test, cable wire resistance, switches, connectors, contact resistance of relays, coils, motors, and equipment casings, thunder protection belts, and ground Connection resistance test between metal components of beams, structures, cabinets, steel bars, water pipes, windows, guardrails, radiators, assembly lines, etc. It is widely used in telecommunications, electric power, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding grids, avoid thunder rods, etc.
ES3070 handheld DC resistance tester consists of a host, monitoring software, test lines, communication lines, etc. The handheld and portable design of the host is convenient for on-site application, with charging function, no need to find electricity on site, full-color large-screen LCD display, easy to use, touch screen operation is convenient and easy to use, and the port is overloaded. Large-capacity storage of 500 sets of data, resistance measurement range:10.0uΩ-50.00KΩ, measurement accuracy:0.2%. The upper computer software has functions such as historical data reading, consulting, saving, and reporting.
