Low temperature specific heat capacity tester/Test method for specific heat capacity/Specific heat capacity analyzer

The instrument refers to GJB 330A-2000 solid material 60-273K specific heat capacity test method (60-373K adiabatic method) design and manufacture. All measurement and control are controlled by computer to reduce human error and improve testing accuracy. The automatic control, data acquisition and processing, display and print-out of the instrument are realized by computer interface operation.

The instrument adopts adiabatic method to test the specific heat capacity of solid (powdery, small piece or small piece) metal and non-metal materials at low temperature, widely used in production enterprises, quality inspection departments, universities and research institutes and other scientific research units.
