✦ Synopsis

The construction of a fully automated adiabatic calorimeter for the temperature range 50-350 K is described. Appropriate operation of the calorimeter was tested by measuring the specific heat of a pure copper sample with a mass of 0.36 g. The measurements showed agreement within 4-1.5% of the standard literature values. Some results obtained for niobium hydride are also reported.

The equipment described was designed to control and stabilize temperature in the range of 1.5-350 K in a liquid helium type cryostat. The temperature sensor was a germanium resistor for the range 1.5-100 K and a platinum resistor above 60 K. The long-time temperature stability was 1 x 10 -4 K b -1 u
