华测差热分析仪HCCR-3000
一、华测型号（HCCR-3000）
二、华测产品简介：
差热分析（DTA）是在程序控制温度下，测量物质和参比的温度差和温度关系的一种技术。当试样发生任何物理或化学变化时，所释放或吸收的热量使试样温度高于或低于参比物的温度，从而相应地在差热区线上可得到放热或吸热峰。差热曲线（DTA）是由差热分析得到的记录曲线。曲线的纵坐标为试样与参比物的温度差（△T），向上表示放热反应，向下表示吸热反应。差热分析也可以测定试样的热容变化，它在差热线上发映出基线的偏离。

HCCR-3000 China Measurement differential thermal analyzer
A model (HCCR-3000)
Two, product introduction:
Differential thermal analysis (DTA) is in the temperature control program, a technique for measuring material and reference temperature difference ratio and temperature relationship. When the specimen is any physical or chemical change, release or absorb heat so that the temperature is higher or lower than the reference temperature, accordingly in hot line is exothermic or endothermic peaks. The differential thermal curve (DTA) was recorded by the differential thermal analysis curve. The ordinate of the curve for sample and reference temperature difference (T), to express the exothermic reaction, down that endothermic reaction. Differential thermal analysis of heat capacity change can also be measured sample, it reveals the difference from baseline in hotline.
