HEC-108 Intelligent Metal Resistivity & Resistance and Conductivity Measuring Instrument

HEC-108 intelligent metal conductor resistivity meter is a high-resolution and high-precision desktop model based on HEC-108 series of intelligent resistivity meters. It can be used to measure the resistivity and conductivity of metal wires, bars and other materials, as well as the resistance and meter resistance of stranded wires and cables. It adopts current-voltage four-terminal measuring method, advanced electronic techniques, singlechip technique and automatic detection technology. Their performances completely accord with the technical requirements of GB/T3048.2 and GB/T3048.4. It is widely used in electric power, electric wire and cable industry, scientific research institutions, colleges and universities, and verification institutions at all levels.

• Measure the conductivity, resistivity, meter resistance and DC resistance of motor, transformer, etc. of the wire, pole and bar with the maximum diameter of 1-45mm.
• The resolution of the instrument is up to 10-8 Ω (0.01 μ Ω), which ensures the measurement accuracy of the resistance and conductivity of the metal conductor with the maximum diameter up to Ø 45mm (sectional area up to 1589mm2).
• Configure high-precision (± 0.1 ℃) temperature sensor or test fixture with high-precision conductor temperature sensor, greatly improving the accuracy of temperature automatic compensation in measurement.
• Combining advanced electronic, singlechip and automatic measurement techniques in one instrument, with superior automatic functions and simple operation.
• All measured numerical values can be obtained by just one press on the key without any calculation. The instrument is adequate for continuous, fast and accurate measurements.
• AC power supply design, suitable for field use.
• With large screen and font. Can display measured values and auxiliary parameters at the same time, including resistivity, conductivity, resistance, temperature, measuring current and temperature compensation coefficient.
• The functions of automatic constant current selection, automatic current reversal, automatic zero point correction and automatic temperature compensation are maintained for every measurement, to guarantee the accuracy of measured value.
• Special portable four-terminal measuring fixture is suitable for fast measurements of different materials and the wire/bar with different standards.
• The build-in data accumulator can record and save 1000 groups of measuring data and parameters. Connecting it to the host computer, the complete report can be generated.
• 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.
