Suitable for the measurement method of the coefficient of thermal expansion (CTE) of the GB/T3074.4 graphite electrodes,
GB/T3074.4 graphite electrode coefficient of thermal expansion (CTE) measurement method
       1, the maximum temperature :0-1200 ℃,
    2, the heating rate :0-100 degrees / minutes adjustable temperature control of computer programs.
       3, a computer automatically calculate the coefficient of expansion, the expansion coefficient, the amount of linear expansion, acute and thermal expansion.
      Automatically calculate the compensation factor and automatic compensation can also be manually corrected (Online).
      5, automatically recording, storing, printing the number noted in print temperature - expansion coefficient curve.
                         The temperature spacing free to set minimum spacing of 1 ° C.
      6, the expansion value measurement range: ± 5mm.
      7, measuring the expansion of value-resolution 0.1-1um automatic calibration range.
      8, the sample range (2-15) x (2-15) × (20-150) mm
      9, imported linear bearing drive, expansion value excellent friction transmission, transmission accuracy and repeatability.
     10, system measurement error: ± 0.1-0.5%.
      11, the power supply voltage: 220V ± 10%, 2KW.
      12, the instrument is equipped with a standard computer interface, associated with a general-purpose computer, all test operations are computer interface, easy to operate, easy to learn and provides a full set of software.
