Product Details

  • I、Equipment introduction

    This product is mainly used for viscosity measurement of high temperature liquid metal, molten salt, thermoelectric functional materials and other low viscosity and high temperature samples. The test method is vibrating cup method, and the maximum testing temperature is 1000 ℃. It has the advantages of full sealing, corrosion resistivity, high test accuracy and good stability.

    II、Main Technical Parameters

    The rotary viscometer can achieve the following indicators:

    1) Test range 1-20cp (mPas);

    2）＜5%;

    3) Repeatability ＜ 5%;

    4) Testing temperature range: RT-1000oC;

    5) The maximum heating rate is 20 ℃/min;

    6) Temperature accuracy: 1 ℃;

    7) Thermocouple: S type;

    8) Test atmosphere: noble gas.
