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-1000A：Select 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-1000B：Select 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.
