Tcjt-31 differential scanning calorimeter can be used to measure the oxidation induction time of materials, the curing reaction temperature ａnd thermal effect of polymer materials, the phase transition temperature ａnd thermal effect of materials, the crystallization, melting temperature ａnd thermal effect of polymer materials, ａnd the glass transition temperature of polymer materials. The experimental objects are: solid, liquid, viscous samples, except gas. Put the sample ａnd reference material into the crucible respectively, ａnd then put them into the furnace for programmed heating to change the temperature of the sample ａnd reference material. If the heat capacities of the reference material ａnd the sample are the same, ａnd the sample has no thermal effect, the temperature difference between them is almost "zero", ａnd a smooth curve is obtained. With the increase of temperature, the sample has thermal effect, while the reference material has no thermal effect, there is a temperature difference between them, which shows as a peak in the DTA curve. The larger the temperature difference, the larger the peak, the more times the temperature difference changes, ａnd the more number of peaks. The peak upward is called exothermic peak, ａnd the peak downward is called endothermic peak.

1. New furnace structure, better resolution, resolution ａnd baseline stability;

2. The digital gas mass flowmeter can accurately control the purge gas flow, ａnd the data is directly recorded in the database;

3. The instrument can adopt two-way control (host control ａnd software control), with friendly interface ａnd easy operation.
