1. Doppler flowmeter
2. Basic principle of differential scanning calorimeter (DSC) based on DSC principle
Differential scanning calorimeter is equipped with two sets of compensating heating wires under the sample and reference material containers. When a temperature difference Δ T occurs between the sample and the reference material due to thermal effects during the heating process, the current flowing into the compensating heating wire changes through a differential thermal amplification circuit and a differential thermal compensation amplifier. When the sample absorbs heat, the compensation amplifier immediately increases the current on one side of the sample; On the contrary, when the sample releases heat, the current on one side of the reference material increases until the heat on both sides is balanced and the temperature difference Δ T disappears. There are two types of DSC instruments: power compensation DSC and thermal flow DSC. DSC is a dynamic calorimetry technology, and the important calibration for DSC instruments is temperature calibration and calorimetry ca
