摘要：

We describe an automated calorimeter for measurement of specific heat in the temperature range 10 K > T > 0.5 K. It uses sample of moderate size (100-1000 mg), has a moderate precision and accuracy (2%-5%), is easy to operate and the measurements can be done quickly with He-4 economy. The accuracy of this calorimeter was checked by measurement of specific heat of copper and that of aluminium near its superconducting transition temperature.
