Netzsch DSC
(For Operation: ASTM E 1269-05, ASTM E 1356-08, ASTM D 3418-08, ASTM E 793-06; For Calibration: ASTM E 967-08, ASTM E 968-02)

TPRL, Inc. uses a Netzsch Differential Scanning Calorimeter for measuring specific heat at high temperatures (500°C to 1400°C.

The Netzsch DSC operates according to the heat flux principle. Using this method, a sample and a reference are subjected to a controlled temperature program (heating, cooling or isothermal). The actual measured properties are the temperature of the sample and the temperature difference between sample and reference. From the raw data signals, the heat flow difference between sample and reference can be determined. By comparing this heat flow rate with the rate measured during the heating of a known mass of sapphire, the specific heat is calculated. The experiments are performed under computer control and specific heat is calculated in Joules/(gm K) and BTU/(lb F) (which equals Cal/(gm C) ) at the related temperature intervals. The DSC's are periodically checked by running either NIST sapphire or alumium as a sample and the results are compared to the NIST values.
