We describe a thermal relaxation calorimeter which has been developed to investigate the thermal property characteristics of bulk films as small as 1 mg over the range of temperatures from 4 K to 35 K. The calorimeter is designed to be attachable to various liquid helium dewars to provide minimum liquid helium consumption and faster thermal cycling while demonstrating high sensitivity and reproducibility. Details of the calorimeter and its performance are given. Preliminary thermal property results associated with the sapphire sample holder are provided to show reproducibility of the measurements.
