    5. SELECTION GUIDE

      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.

      Battery power supply has small size thus easy to carry, suitable for indoor and open-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.

      One instrument has multiple applications, and has three measurement interfaces: interface of conductor resistivity/conductivity measurement, interface of wire/cable comprehensive parameter measurement and interface of wire/cable direct-current resistance measurement (TX-300B model).

      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.

    Brief description:

    TX-300A: Equipped with default 300mm measuring fixture, measuring the material whose diameter of line is between 0.1mm to 10mm, easy to carry, suitable for indoor and open-field use.

    TX-300A: Selecting 300mm measuring fixture or normal one meter measuring fixture, TX-300A compared to one more measuring project to measure resistance per kilometer

    TX-1000ASelect from all the one meter measuring fixtures, the measured material’s maximum diameter is 44mm. Compared with the 300series, 1000 series’ measurement range is wider, resolution is higher, and the measurement minimum is 0.01μΩ. Extra 1000A2/B/B1 model fixtures can be selected, and it can measure 1-44mm material.

    TX-1000BSelect from all the one meter measuring fixtures. Compared with the 1000A model, it has the same basic performance, removes the resistivity and conductivity from the measuring project but adds resistance per kilometer, be more suited to measure strand wire.
