Abstract As the standard of the absorbed dose, graphite calorimeter demands high recurrence rate. Analysis shows the performance of the graphite calorimeter system of NIM, the measurement of electric energy (power), the conversion relation between electric energy and radiation energy, and the measurement of the value of the absorbed dose reproduction. Related technical index was explained, meanwhile, it's stability was given. In order to test the measurement of the standard, specific heat capacity was measured. The measurement results was complared with BIMP's results, deviation is less than 0.1%.
