● It is used to measure the conductivity, resistivity, meter resistance of metal foil, metal strip and wire, and DC resistance of motor, transformer, etc.

● It integrates advanced electronic technology, single-chip technology and automatic detection technology, with strong automatic function and simple operation;

● only press the key once, all measured values can be obtained without any calculation, suitable for continuous, fast and accurate detection;

● battery powered design, small size, easy to carry, suitable for field and field use;

● large screen, large font, which can display resistivity, conductivity, resistance and other measured values and temperature at the same time, test current, temperature compensation coefficient and other auxiliary parameters, very intuitive;

● one machine is multi-purpose, with three kinds of measuring interfaces, i.e. conductor resistivity, conductivity measurement interface, and metal foil resistivity measurement interface;

● each measurement, with automatic selection of constant current, automatic current commutation, automatic zero correction, to overcome the error caused by the thermal voltage to line resistance, and ensure the accuracy of each measurement value;

● the instrument has its own environmental temperature sensor and a variety of material temperature coefficients for selection to complete the automatic temperature compensation;

● a series of calibration resistors can be selected and matched with relevant software to facilitate the automatic calibration of the instrument;

● The unique portable four terminal test fixture is suitable for rapid measurement of different materials and specifications of wire or bar;

● the built-in data memory can record and save 1000 sets of measurement data and parameters, and connect the upper computer to generate a complete report.
