Measurement principle

Thermal pulse specific heat measurement is based on flat-top pulsed magnetic field technology.We use high efficiency heating source and heat conduction material, high sensitivity low temperature thermometer, and small specific heat measurement chip to achieve pulse field specific heat measurement. First, the sample is cooled to the lowest temperature to be measured. Then a small amount of heat ∆Q is applied to the sample by means of a pulse current during the flat-top magnetic field. The heat capacity of the sample can be calculated by measuring the temperature change ∆T of the sample rise with a thermometer.
