Abstract
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%.
