We have developed an educational model of power compensated differential scanning calorimeter with a few modifications for the science students of academic institutions. In order to demonstrate the instrumentation and analytical aspects involved in the system, all the building blocks are constructed using local industry and are explained in detail. A few deviations from the conventional model have been attempted without compromising the basic calorimetric concept. This is done with a due consideration for cost factor and also to keep the openness in the development. The paper discusses the calibration procedure of the modified system to arrive at the on-set temperature and enthalpy of the samples. We are able to measure the onset temperature within ±1.18 °C and the enthalpy values using this proto version with an error 5%.

我们已经开发了功率补偿差示扫描量热仪的教学模型，并对学术机构的理科学生进行了一些修改。为了演示系统中涉及的仪器和分析方面，所有构建块都是使用本地行业构建的，并进行了详细说明。在不损害基本量热概念的情况下，尝试了与常规模型的一些偏差。这样做时要充分考虑成本因素，并保持开发的开放性。本文讨论了修改后的系统的校准程序，以达到样品的设定温度和焓。我们能够使用此原型版本在±1.18°C的范围内测量起始温度和焓值，误差为5％。
